Therefore, the reception interrupt routine shown in the flowchart of FIG. 10 will be explained first.

Now, the parent ECRME receives an interrupt request transmitted from the central management unit CQ. ~ When MEn receives, its parent ECR
Old M. ~MEn first determines whether the received data is text or not, and if the determination result is not text, further determines whether or not it is a bowling signal POLL, according to the flowchart in FIG. If the determination result is the bowling signal POLL, the following processing is performed. ■ First data presence/absence determination flag DF
When I is set, that is, when there is response data in the first buffer memory 45, the data in the first buffer memory 45 is transmitted to the central management unit CQ.

■ The first data presence/absence determination flag DFI is reset, that is, there is no response data in the first buffer memory IJ45.

After transmitting the OT to the central control device ℃Q, if the sending end flag SFF is set, various line-related flags are reset.

In addition, in determining whether or not the received data is text, if it is text, an acknowledgment signal ACK is sent to the central management device CQ on the condition that there is no error in the received text, and then It is determined whether or not it is a command, and if the determination result is not a command, that is, if it is setting data, etc., the following processing is performed.

■ When the sequence is normal, after setting the number of blocks of the received data in the block counter BC,
The received data is transferred to the setting collection data storage area 50. ■ Not a normal sequence and a child ECRSE.

, ~SEnn, the abnormality detection flag DEF during transmission processing is set, and then various line-related flags are reset. ■ Not a normal sequence and a child ECRSE.

, ~ When data is not being transmitted to the SE skin, the first sequence error flag SEFI is set, and then various line-related flags are reset. In addition, in determining whether or not the received data is a command, if it is a command, then it is determined whether or not the sequence is normal as shown in FIG. 10b, and the determination result is normal. On the condition that it is not a sequence, proceed to the process of (1) or (2) above.

On the other hand, if the above judgment result is a normal sequence, the type of the next received command is determined, and the following processing is performed depending on the type of command. ■ If the register specification text command is '200', on condition that it is in the READY state, set the reception availability determination flag JKF, set the setting reception availability response data 'C' in the first buffer memory 45, and then A first data presence/absence determination flag DFI is set.

Incidentally, although not shown here, even if the state is not in the READY state but in the BUSY state, the setting reception failure response data 'A' is set in the first buffer memory 45.
■ If the setting check command is '302', the setting completion response data 'F' is set in the first buffer memory 45, and then the first
The data presence/absence determination flag DFI is set. In addition,

(2) If the setting business command is '305', then it is determined whether the business command reception flag GKF is set.

At this time, if the business command reception flag GKF is not set, the business command reception flag GKF is not set.
After setting KF and business response data 'E' in the first buffer memory 45, the first data presence/absence determination flag DFI is set. If the business command reception flag GKF is set, then it is determined whether or not the second data presence/absence determination flag DF2 is set, and the second data presence/absence determination flag DF2 is set.

(2) If the full inspection service command is '360', the process proceeds to the process of (2) to determine whether the service command reception flag GKF is set or not, and the process is performed according to the result of that determination.

■ The following processes are based on various business commands, but are omitted here.

Now, based on the processing in the reception interrupt routine of FIG. 10 explained above, next
M.E.

~MEn and child ECRSE. , to SEnn, and conversely, the case of collecting data from them will be explained along the flowcharts of FIGS. 9a and 9b. First, from the central management device CQ to the parent ECRME.

~MEn and child ECRSE. , ~ When setting data to SEnn, the central control unit CQ uses key operations on the keyboard 3 to input setting data such as department codes, plot codes, etc. and register designation text that specifies the terminal where the setting data is to be set. After setting to RAM6,
For example, if you press the "A" key, the register specification text command '200' will be sent to each parent ECRME. ~Sent to MEn. Then, the parent ECRME receives the register specification text command '200'. ~MEn transmits the acknowledgment signal ACK to the central management unit CQ according to the reception interrupt routine shown in the flowchart of FIG.
At the same time, on the condition that the processing in (2) is in the READY state, the reception permission determination flag JKF is set, and the set reception permission response data 'C' is set in the first buffer memory 45. Set the data presence/absence determination flag DFI. )I do. At this time, the above ■
Since the reception determination flag JKF is set by the process, the process in FIG. 9a proceeds from loop L to loop L2 and sets the first sequence error flag SEF.
The key capture processing subroutine is repeated to determine whether I and the business command reception flag GKF are set. On the other hand, when the acknowledgment signal ACK is received by the central management device CQ, the boring signal PO is sent from the central management device CQ.
LL is sent.

Then, the parent ECRME. When ~M old n receives the bowling signal POLL, since the first data presence/absence determination flag DFI is set, the above process (■) (setting reception set in the first buffer memory 45 Send response data 'C' to central management unit CQ.
)I do. When the setting reception ready response data 'C' is received by the central management device CQ, an acknowledgment signal ACK is transmitted from the central management device CQ. Then, the parent ECRME. ~M old n is its acknowledge signal ACK
When it receives, it performs the process (2) (resetting the first data presence/absence determination flag DFI and transmitting the end of transmission signal EOT). This ending
of transmission signal EOT is central control unit C
When received by Q, the register designation text set in the RAM 6 is transmitted from the central management device CQ. Then, the parent ECRME. ~MEn transmits the acknowledgment signal ACK to the central control unit CQ, and according to the process in (2) above, sets the number of blocks of the received register designation text in the block count BC, and sets the register designation text in the set collection data storage area. Transfer to 50. When this acknowledgment signal ACK is received by the central management device CQ, a setting check command '302 is transmitted from the central management device CQ. Then, the parent ECRME. ~MEn is the setting check command'
302, it sends an acknowledge signal ACK to the central management device CQ and processes the above (if the setting is done correctly, the response data 'F' is received, otherwise the response data 'G' is sent to the first After setting in the buffer memory 45, the first data presence/absence flag DFI is set. Thereafter, when the boring signal POLL transmitted from the central management device CQ is received, the process of (2) is performed, and when the acknowledge signal ACK is received, the process (2) is performed, and the transmission of the register designation text is completed. Subsequently, a department setting command '220' is transmitted from the central management device CQ, and setting data is transmitted in the same manner as described above.

That is, the parent ECRM old. ~M old n is first central management device C
When the department setting command 1220' from Q is received, the above process (■) is performed, and the received department setting command '2' is executed.
201 is set in the command register CR, and the next time a boring signal is received, the above process is performed. Next, when the acknowledge signal ACK is received, the above process is performed. Next, when the department setting data is received, the above process is performed. Perform the process described above, and then perform the process described above when the setting check command '302' is received, then perform the process described above when the boring signal POLL is received, and then perform the process described above when the acknowledge signal ACK is received. Perform the process ① above. That's it for parent ECRME. ~MEn's setting collection data storage area 5 is in a state where department setting data and register designation text are stored. After this, the central management unit CQ
A setting task command '305' is transmitted from the terminal.

Then, the parent ECRME. ~MEn, upon receiving the setting business command '308, sends an acknowledge signal ACK.
is returned to the central management unit CQ, and the process (2) above is performed. At this time, since the business command reception flag GKF is set by the process (2) above, the process in FIG. 9a proceeds from loop L to the next process. During this process, if an abnormality occurs, the first sequence error detection flag SEFI is set by the process (2), and the process returns to loop L again. On the other hand, when proceeding from loop L2 to the next process, first the register specification text stored in the setting collection data storage area 501 is converted to an inline address and written to the specified register table memory 48, and the specified After setting the number of registers in the terminal counter TC and setting the program to start the work, the child ECRSE is designated to transmit data from the designated register table memory 48. ,~SEnn or parent ECRM old. ~Search to see if MEn exists. Here, if there is an ECR designated for data transmission, its inline address is set in the address register AR, and then the timeout flag TOF, which is set when the transmission time set in the timer counter TOF has elapsed, is not set. After setting the program for starting work, the transmission start is turned on, provided that it is within the specified transmission time. Then, the child ECRSE whose department setting data stored in the setting collection data storage area 5 corresponds to the line address set in the address register AR. ，
- Transmission settings are made to SEnn. At this time, "Although not shown, each time the setting (or collection) work for child ECRSE.,~SEnn is completed, the terminal counter T
The data of C is counted down to '1', the setting collection completion flag SKF is set, and the setting (or collection) of the child ECRSE is completed. , ~SEnn, the task completion determination flag 48b corresponding to the line address is set. Also, during transmission during this period, if the BUSY state is reached, the second sequence error detection flag SEF2 is activated.
However, when there is no response, a third sequence error detection flag SEF3 is set. on the other hand,. 9th
The process in Figure a is that after turning on the transmission start mentioned above,
Proceeding to a loop, the subroutine of determining whether the setting collection completion flag SKF, the second sequence error detection flag SEF2, and the third sequence error detection flag SEF3 are set, and key capture processing are repeated.

Here, the child ECRSE corresponds to the line address set in the address register AR. , ~ When the setting work for SEnn is completed, the setting collection completion flag SKF is set, so the process in FIG.
Then proceed to the line control 1 routine. In the line control 1 routine, as shown in the flowchart of FIG. 9b, first the setting collection completion flag SKF is reset, and then it is determined whether the addition data discrimination flag KDF is set.

This addition data discrimination flag KDF is set when a business command such as inspection or settlement is received, but is not set when a business command such as setting is received for other business. Therefore, in this case, since the addition data discrimination flag KDF is not set because it is a setting service command, the error detection flag DEF during transmission processing is set after the addition data discrimination flag KDF is reset. Determine whether it is true or apricot. At this time, if there is an abnormality in the above processing, the transmission processing abnormality detection flag D is
Since EF is set, the process returns to step (2) of the monitor routine shown in FIG. It is determined whether the address of the specified register table memory 48 has reached the end. Then, on the condition that data transmission with all the ECRs has not been completed and that the address has not reached the end, the process returns to (2) in FIG. 9a and data transmission with the next ECR is performed. Note that if the above address has reached the end, the address is initialized and the timer counter WC is
As a result of the judgment, if there is activation, the transmission time is set directly in the timer counter WC, and if not, the transmission time is set in the timer counter WC according to the number of remaining units, and then the process returns to (2) in FIG. Also, the 9th
In loop L3 in the figure, when the second and third sequence error detection flags SEF2 and SEF3 are set,
That is, the child ECRSE. ,~BUSY during transmission with SEnn
state or no response state, the process advances to the line control routine shown in FIG. 9b, and a subroutine for addition processing is performed depending on the state of the addition data discrimination flag KDF. In this way, the child ECRSE is set in the designated register table memory 48.

, to SEnn are sequentially set. Then, when the data transmission with all the set ECRs is completed, or when the set transmission time has elapsed and the timeout flag TOF is set, the routine shifts to the data sending routine. In the data sending routine, according to the flowchart shown in FIG. 9c, the child ECRSE is first set by the task completion determination flag 48b of the designated register table memory 48.

, ~SEnn and parent ECRME. ~ Create information on whether the settings (or collection) for MEn have been completed to be sent to the central management device CQ, and send the created data to the second
After setting the data in the buffer memory 46 and subsequently setting the second data presence/absence determination flag DF2, it is determined whether or not it is the final data. If it is not the final data, it is set directly, or if it is the final data, the sending end flag SFF is set, and then the subroutine of the key capturing process is repeated until the second data presence/absence determination flag DF2 is reset.
During this period, when the bowling signal POLL is received from the central management device CQ, the sending data set in the second buffer memory 46 is transmitted to the central management device CQ by the process of (2) above, and when the acknowledgment signal ACK is received next, the above-mentioned ■ Perform the processing of '. Then, since the second data presence/absence determination flag DF2 is reset in accordance with the process of ``2'', it is next determined whether or not the abnormality detection flag DEF during transmission processing is set. At this time, if the abnormality detection flag DEF during transmission processing is set, the abnormality detection flag DEF during transmission processing is reset, and after resetting various flags, the process returns to ■ of the monitor routine, but the abnormality detection flag DEF during transmission processing is reset. If not set, the department setting command '220' stored in the command register CR is printed in the journal on the condition that the final data has been transmitted, and then the process returns to step (2) of the monitor routine. By the above operations, the parent ECRM
E.

~MEn and child ECRSE. , ~ When a registration operation is performed with various data set in SEnn, the parent ECRME. ~MEn and child ECRSE. ，〜
Various registered data are stored in the RAMs 26 and 56 of the SEnn. To register, first enter the price of the product using the layer number keys 31 and 61, then press the amount keys 38 and 68, then enter the department code to which the product belongs using the layer number keys 31 and 61, and then press the department key. 37
, press 67. Further, if the unit price of the Memo River product corresponding to each department key 32, 62 is preset, one product can be registered simply by pressing the department key 32, 62. Therefore, next, the parent ECRME is sent from the central management device CQ.

~MEn and child ECRSE. , ~ When collecting registered data stored in SEnn, the central management unit CQ stores in advance in RAM 6 register designation text that designates the terminal from which data is to be collected by key operations on the keyboard 3.
After setting, for example, if you press the "B" key, the register specification text will change to the parent ECRM old, similar to the setting task described above.
~MEn setting collection data storage area 501 is set. Furthermore, even during this period, the parent ECRM remained unchanged. ~M old n
Now, the registration work can be performed by the key import processing subroutine in loops L, , -. After this, the central management device CQ transmits a complete inspection work command '360'.

Then, the parent ECRME. When ~M old n receives the all inspection work command '360', it performs the process described above and sets the received all inspection work command '3601' in the command register CR, and then sends an acknowledge signal ACK.
is returned to the central management unit CQ. At this time, since the business command reception flag GKF is set by the process (2) above, the process in FIG. 9a proceeds from loop L2 to the next process. During this process, if an abnormality occurs, the first sequence error detection flag SEFI is set by the process (2), and the process returns to loop L. On the other hand, when proceeding from loop L to the next process, first the register specification text stored in the setting collection data storage area 50 is converted into an inline address and written to the specified register table memory 48, and the specified number of registers is After setting the terminal counter TC and setting the program to start business, the child ECRS designated for data transmission from the designated register table memory 48
E. -~SEnn or parent ECRME. ~Search whether there is MEn or Anzu. Here, the E
If there is a CR, its inline address is set in the address register AR, and transmission activation is turned on on the condition that the timeout flag TOF is not set, that is, within the set transmission time. Then, the all inspection work command set in the command register CR

~M Send to old n. On the other hand, parent ECRME.

~MEn is child ECRSE. , ~ The data sent from the SE skin is transferred to the setting collection data storage area 50, and the process proceeds to loop L3 shown in the flowchart of FIG. The subroutine of determining whether the flag SEF2 and the third sequence error detection flag SEF3 are set and key capture processing is repeated.
Therefore, the child ECRSE. , ~ even during transmission with SEnn. ~M old n is in a state where the registration obligation can be performed by the key import processing subroutine of loop L3. Here, the child ECRSE corresponds to the line address set in the address register AR. ,~SE
When the collection work from nn is completed, the setting collection completion flag SKF is set, so the process in FIG. 9a proceeds from the loop to the line control 1 routine.
In the line control 1 routine, as shown in the flowchart of FIG. 9b, first the setting collection completion flag SKF is
is reset, and then it is determined whether the addition data discrimination flag KDF is set.

In this case, since it is a full inspection service command, the addition data discrimination flag KDP is set, so after performing addition processing and transferring the result to the addition data storage area 49, the addition data discrimination flag KDF is reset. After processing, the abnormality detection flag DEF during transmission processing
Determine whether it is settomire or apricot. At this time, if there is an abnormality in the above process, the abnormality detection flag DEF during the transmission process has been set by the process (2) above, so the process returns to (2) of the monitor routine shown in FIG. 9a.
If not set, then it is determined whether data transmission with all ECRs set in the designated register table memory 48 has been completed and whether the address of the designated register table memory 48 has reached the end. And all E above
Provided that the data transmission with the CR has not been completed and that the address has not reached the end, the process returns to (2) in FIG. 9a and data transmission with the next ECR is performed. In this way, the child ECRSE is set in the designated register table memory 048. ,~As we collect the data stored in SEnn, those data become the parent ECRME. ~MEn is stored in the addition data storage area 48. Then, when data transmission with all set ECRs is completed, or when the set transmission time has elapsed, the timeout flag TO
When F is set, the inspection data stored in the addition data storage area 48 is transmitted to the central control unit CQ according to the data transmission routine shown in FIG. 9c. That is, in the data sending routine, the specified register table memory 4
8, the child ECRSE is activated by the task completion flag 48b. ，〜
Information on whether collection has been completed for SEnn and data stored in the addition data storage area 49 are created for sending to the central management device CQ, and the created data is set in the second buffer memory 46, Subsequently, after setting the second data presence/absence determination flag DF2, it is determined whether the data is the final data. If it is not the final data, the key capture processing subroutine is repeated directly, or after setting the sending end flag SFF if it is the final data, the key capture processing subroutine is repeated until the second data presence/absence determination flag DF2 is reset. Therefore, during this period as well, the parent ECRME. ~ME
At n, the registration work can be performed by the key capture process of the data sending routine. Also, during this time,
When the bowling signal POLL is received from the central control device CQ, the second buffer memory 46 is
Sends the transmission data set to the central control unit CQ,
Next, when the acknowledgment signal ACK is received, the above-mentioned process 2' is performed. Then, since the second data presence/absence determination flag DF2 is reset in accordance with the process of ``2'', it is next determined whether or not the abnormality detection flag DEF during transmission processing is set. At this time, if the abnormality detection flag DEF during transmission processing is set, the abnormality detection flag DEF during transmission processing is reset, and after resetting various flags, the process returns to ■ of the monitor routine, but the abnormality detection flag DEF during transmission processing is reset. If not set, on the condition that the final data has been transmitted, the entire inspection work command '360' stored in the command register CR is printed in the journal, and then the process returns to the monitor routine (2). By the way, as mentioned above, while the setting or collection work is being performed by activation from the central management device CQ, for example, the parent ECRME. ~When an abnormality such as a temporary power outage occurs in MEn, the transmission processing abnormality detection flag DEF
is set, so ■ in the monitor routine in Figure 9a is
The state has returned to . Now, suppose that a power outage occurs during inspection work and when the power is restored, a department setting command '220' is sent from the central management unit CQ, for example, to the parent ECRME. ~MEn is the received department setting command '220' and command register CR
It is determined whether the commands set before the power outage, that is, the all inspection work command '36, are the same. In this case, there is a mismatch between the two, and the total inspection task command '3' set in the command register CR is

When L is received, the total inspection work command request data '1' set in the first buffer memory 45 is transmitted. And this full inspection work command request data '1'
is received by the central management unit CQ, and the request data '1'
When a full inspection task command '360' corresponding to the above is sent from the central management device CQ, the parent ECRME. ~MEn
In this case, since the transmitted command and the command in the command register CR are the same, the power failure recovery processing flag TKF is set. Then, the parent ECRM old. ~ME
At step n, the power outage recovery processing flag TKF in loop L of FIG. I will do it. Therefore, even if an abnormality such as a power outage occurs during the transmission process, the data up to that point will be transmitted to the central control unit CQ, eliminating the time loss of starting the process from the beginning as in the past. can be eliminated. In particular, parent ECRM
E. . . . M old n returns command request data for starting from the current state to the central management device CQ, which has the advantage of eliminating time loss at the time of starting. The above is from the central management device CQ to the parent ECRM.
E. ~MEn and child ECRSE. ．． ~When setting data to SEnn, and conversely when collecting data from them, next is the parent ECRM old. ~In MEn, child ECRSE. , ~ When setting data, for example department data, to SEnn, conversely, the child ECRSE. , ~SEnn will be described. First, parent E
CRME.

~MEn to child ECRSE. , ~ When setting department data to SEnn, the parent ECRME. ~MEn, after register designation text designating the terminal for setting data is previously set in the designation register table memory 48 of the RAM 26 by key operations on the keyboard 23, the next key operation is performed. (1) After adding the layer number of the department code using the layer number key 31, press the department key 37. Then, after adding the layer number of the plot code using the calendar number key 31, press the department key 37.

After inputting this operation for each department, the substitute key 34 is finally pressed as the closing key. (b) After the operation in (1) above, press the setting/reading key 36.

Then, the parent ECRME.

〜M old n is the 11th
According to the flowchart shown in FIG. a, it is first determined whether there is activation from the central management device CQ. If there is an activation from the central control unit CQ, an error will occur, but if there is no activation, then the department data such as the department code and plot code inputted by the operation in (1) above are set and sent to the collection data storage area 50. After setting, the number of blocks of the setting data is set in the block counter BC. Thereafter, when the above operation m) is performed, it is first determined whether or not there is activation from the central management device CQ, according to the flowchart shown in FIG. 11b. If there is a start from the central control unit CQ, an error will occur, but if there is no, then set the department setting command '220' in the command register CR, set the business command reception flag GKF, and set the parent start flag MF. After setting, proceed to step 2 shown in Fig. 9. Therefore, since the subsequent processing is performed according to FIG. 9, the setting work is performed in the same manner as when starting from the central management device CQ. On the other hand, parent ECRME.

~MEn to child ECRSE. , ~ Parent ECRM old when collecting data stored in SEnn. ~ME
At n, the register specification text specifying the terminal from which data is to be collected is entered in advance by key operations on the keyboard 23.
After setting in the specified register table memory 48 of AM26, press Deposit/Cash Total 1136. Then, the parent ECRM old.
~MEn according to the flowchart shown in FIG.
First, it is determined whether or not there is activation from the central management device CQ. If there is a start from the central control unit CQ, an error will occur, but if there is no, then set the full inspection work command '360' in the command register CR, set the work command reception flag GKF, and set the parent start flag. After setting the MF, proceed to step 2 shown in FIG. Therefore, since the processing will be carried out according to this FIG. 9 from now on, the central management unit CQ
Inspection work is carried out in the same way as when starting up. Thus, the child ECRSE.

,~SE settings and inspections are performed from the central management device CQ as well as from the parent ECRME. ~MEn can also do this. By the way, for example, the child ECRSE is activated by the central management device CQ. , ~ Data collected from SE blood is the parent ECRME. ~ Suppose that an abnormality occurs in the central management unit CQ and data transmission is no longer possible at the stage when data is collected in MEn.If the data collection task is a settlement task, the child ECRSE. , ~SEnn has been cleared, making post-processing extremely troublesome. In such cases, the parent ECRME. -MEn, first input the program selection data by pressing the calendar number key 31, for example, the "8" key, and then press the deposit/account key 42. Then, the parent ECRME. ~MEn first determines whether or not there is activation from the central management device CQ, according to the flowchart shown in FIG. If there is a startup from the central management unit CQ, an error will occur, but if there is no startup, the next collection task will be 1.
It is also determined whether or not the process is completed. Here, if the collection task has been completed by even one printer, the collection data stored in the addition data storage area 50, that is, the settlement data, is printed out by the printer 28 on the condition that the task is a settlement task. Therefore, even if data transmission to the central management unit CQ becomes impossible during settlement data collection, the parent ECRME. - Settlement data collected in MEn to its parent ECRME. Since printing can be forcibly performed by key operation of ~MEn, post-processing in the event of an abnormality can be performed easily and in a short time. In addition, in the above explanation, the central management device CQ
The specified register table memory 481 is set by the register specifying text sent from the register specifying text or the register specifying text input from the keyboard 23.
S.E.

,~SE skin and pro-ECRME. Although the case where transmission work is performed for ~MEn has been described, for example, the child ECRSE is always set in the register table memory 47 when a certain function key is not pressed. ,~SE
Blood and parent ECRME. -Transmission services are now being carried out for MEn. Therefore, depending on whether or not the function key is operated, it is possible to easily select whether to target all ECRs or only a designated ECR. Also, parent ECRME. ~MEn is child ECRSE. , ~ During data transmission with SEnn,
The register number corresponding to the data in the address register AR, that is, the child ECRSE where data transmission is currently being performed.
, ~SEnn are transmitted to the central control unit CQ and displayed on its display 4. Therefore, the child ECRSE that is currently transmitting data from the display on this display 4 is out of operation. ,~SE skin can be confirmed.
According to the present invention, in addition to data transmission operations transmitted from the central management device, data transmission operation instructions based on keyboard operations of the parent ECR are stored in a command register, thereby controlling data transmission operations with each child ECR. For example, even if an abnormality occurs in the central management device and the transmission operations initiated from the central management device cannot be performed, all transmission operations can be executed through activation from each parent ECR. It does not interfere with transmission operations, and various data transmission operation commands can be stored in the command register based on the first operation on the keyboard, and various data transmission operations can be performed by starting the parent ECR. It is something that can be done.

Furthermore, each parent ECR stores data collected through data transmission operations with the child ECR in its data storage area.
When the parent ECR has collected data collected through transmission operations with child ECRs, the data collected through data transmission operations with child ECRs can be printed based on the second keyboard operation, and an error occurs in the central management unit. This has the advantage that post-processing can be easily performed even when data transmission cannot be performed.
