Description

Detailed Description of the Invention This invention provides a separate operator console control device between the operator console and a higher-level control device such as a computer, and controls input and output of the operator console to reduce the burden on the higher-level control device. As shown in the block diagram of the conventional system shown in FIG. The circuit 100B receives an interrupt signal to the bus BIJ& via the interrupt input circuit 1001, or receives an input signal to the path BIJ8 via the digital input circuit 1002, and also outputs an output address signal to BO2 for the output signal. When an output mode signal or data is given, the output control circuit 1005 decodes them and outputs flicker mode, t or continuous ON to the output control circuit 1012 via the digital output circuit 1006.
However, the input/output device, number of points, wiring, control method, etc. of the operator console had to be designed, manufactured, and tested according to the customer's specifications, so the input/output unit, WI ! There was a desire to standardize interconnection cables to reduce costs and improve reliability and maintainability.

The present invention was made to eliminate the above-mentioned drawbacks, and in order to standardize the following basic functional elements as requested by customers:
F operation ■) Lamp flicker operation ■) Selection of whether output to lamps and relays is controlled by software or hardware ■) Command input switch ON, OFF Exclusive selection operation of only one and corresponding lamp lighting 11) Q-Ray pulse-like ON output operation By combining these, we provide a control method that satisfies customer specifications.

The operation of the control device 31 is similar to that of the other control device 32. Since the operation is the same as that for 3 m, only the control device 31 will be described below.

The devices 9, 1G, 11, and 12 are connected to an input switch 13 and an output device rr114 provided on the operator console 2 by external lines.

Figure @3 is a partially enlarged view of RAM H. RAM 8 includes a switch input state data section 81. Rising state change data section 82
．． An output buffer 83 is provided.

The ROM 7 further stores the management task 08 as well as processing tasks for operator console control. The processing tasks are roughly classified as TK, , and TK, and the details will be described later.@Prior to the following explanation, the following promises are made. That is, 2
The 4 bits of hexadecimal information are combined into a hexadecimal number, and this is
...Represent it as 1, and write a number in hexadecimal notation in the part surrounded by '''.In this case, numbers less than 10 in decimal are also represented in hexadecimal as 0 to 9, but 5-10 The 16 fractions corresponding to the base numbers lO~15 are A and B.

C, D, B, F 0 will be expressed in full alphabet. Therefore, for example, X"lli" is decimal 31.
C3" represents decimal 195.

Next, the input switch 13 provided on the operator console 2
As for, ■ A group of specified bits is set as one group, and each bit included in this group is an independent input switch. ■ An input switch that exclusively selects only one bit among the n bits indicated by nd *. + -ic bit ru BiNA'RY C
There are coded input switches such as ODMD and DgCIMAL (BCD) information, and the input switches belonging to (1) and (2) are further divided into (2) input switches for operation instructions and (2) input switches for status information.

The signal given by the operation instruction input switch is also called a condition change human power signal, and in order to avoid complicating the architecture, the microcomputer uses a small number of blades, and the condition change signal is processed by software to generate the change signal. It is often substituted for. On the other hand, the status information is information that requires complicated processing depending on the operation instruction, and therefore cannot be processed by the control device 31, so it is transmitted to the higher-level control device 1 to request processing.

The encoding method given in (2) is also for status information, and the processing that requires complicated processing is requested to the control device 1.
If you just want to display the input information on the O\tada device 14 without processing it, you can use the well-known numeric keypad output device 1 directly.
Use o to exit.

The output device 14 is ■Numeric keypad output device 10. Coded information output using an on/off output device 11 and a code output device 13, for example, a display; (2) A single bit output string using an on/off output device 11. A display is known.

Next, information flow control between the control devices 1, 31 and the operator console 2 will be explained.

In Figure 2, the device connected to 0PCBUS 9゜1
0.11.12, etc. When the betting circuit is installed as a card unit in the locker of the control device 31, when the shelf slit structure is adopted, and when the card switching board setting structure is adopted depending on the card device position, the The method of accessing the corresponding card differs depending on the switching designation. The identification symbol for this is the physical machine number (PHDN), and the upper control device 1#
c* If there are a plurality of m operator console control devices to be installed, usually m control devices 31. - Various circuits built in each of 3m, namely devices 9, 10, 11, 1
Since the combinations of 2 are individually different, when the control device l accesses the PHDNs of these devices,
Since this increases the burden, an easy-to-use identification symbol is determined separately on the control device l side, and this is used for access. This identification symbol is called the input/output sequence number (LODN), and the input sequence number is divided into the information input sequence number (LODND) and the input sequence number of the status change switch and llCl switch (LODN8), and each output sequence number is designated as the LODNO. In order to convert to the physical machine number PHDN, the information input conversion table 715 shown in FIG. 5 (1), the state change manual conversion table 716 shown in FIG. It has already been mentioned that the information is stored in the control table 71 shown in FIG. When the control device 31 exchanges the identification symbols of input circuits and output circuits with the host control device 1, or accesses the input circuits and output circuits, the control device 31 only needs to access them using the input/output serial number LODN. The contents of the corresponding conversion tables 715, 716, and 717 are regarded as commands and are substantially executed. Conversion table 7
The contents of 15, 716, and 717 form a set of input and output instructions at three consecutive addresses. The first one is shown in Figure 5 (a
), #i (Fig.

In the enlarged view of the output conversion table 717 in FIG. 6, X"DA" is used as the output instruction code (OUTPUT).
D3", and the third check is the return instruction code (RIilT
) as X”C9’, and the second one in the middle is wIc.
Note that the physical machine number Pi-IDN is stored.

As an example of the relationship between a specific serial number and a physical machine number, 9- In Figure 5 (1), the physical machine number PHDN is X148 "~" 4

It can be seen that it is compatible with "IF".

Furthermore, a space is reserved for the locker of the control device 31 assuming the input/output scale of the maximum configuration. Even if the largest input/output circuit is not put into practical use according to customer specifications, changing the size of the table area will break standardization, so the area size is fixed and the area equivalent to unused input/output circuits is Dummy instructions and dummy data are stored in table addresses to prevent processing tasks from stopping or running out of control. Therefore, in the conversion table in Figure 5 (a), the information input serial number LOD
J U is placed at the first of three addresses corresponding to unused circuits, such as where ND is X “OF” and output serial number LODNO is X “2G” in the conversion table in Figure 6.
If you store X"C3" as the MP instruction code, and store appropriately determined jump destination numbers 10-10, JAD, . Even if you access it, the execution result will be the same as no operation, and abnormal operations can be prevented.Next, user task TK1. T
K.

of#! The operator console control device processing flow shown in FIG. 13 will be explained.

The priority of user task TK1 seen from 08 (not shown) is set higher than the priority of TK. It has already been mentioned that the fixed time timer 15 capable of timing out the time T is built into the control device 31. The timer 15 is activated, and when a predetermined time Ti elapses, it generates a signal and uses this signal as a transfer signal to the microprocessor 6, thereby requesting the OS stored in the ROM 7 to start the task TK1. Therefore, task TK.

If you close the relay in task TK and immediately start timer 15, after a certain period of time T1 has passed, task TK will be interrupted and 1 will be relayed to task 1. Since it opens, a pulse-like relay closing output is obtained as a result. ◎ Task TK will be explained. When the control device 31 starts operating, an initial task INI is started, which clears the output buffer, timer, etc., reads the state of the manual switch, and stores it in the switch input state data section 81. The role of this data reading will be described later, but it is because the same logic can be used to identify a change in status, regardless of whether the status change switch is normally open or normally closed. After this, the initial task INI calls task TK. Task TK is the starting address FiNT
First, read the strange power switch (88IN).
). Figure 12 is a breakdown diagram of the input and output. During switch input, the serial number LODN8 of the status change switch input is x"oo" to "OF" as shown in the figure.
It is recognized that HDNX@60"~16Fl#c corresponds. Then, when R8IN is executed for the first time immediately after the initial task INI is executed, the contents of the switch input state data section 81 at that time are zero, but the task TK is completed once. When executing R8IN for the second time or later, the data from the previous execution of R8IN is used as the switch input state data [81
The contents of the data section 81 are compared bit by bit with the newly sensed status switch input data, and the bit that was ``0'' last time changed to ``1'' this time (this bit is (referred to as variable bits) is set to "l", and other than that, "0" → "Q #, # l # → "1"
The bit group in which the unchanged bits of ``1#→``01'' are all set to 0 is ORed with the contents of the rising condition change data section, and stored again in the condition change data section 82 (8 TORN! , ) L,
Furthermore, the current state change switch data is updated to the new data section 81.
Store (STORE,). Therefore, if the rising state change data part 82 is 01010000, and the state data part 81 is 1101011100 previously and 1100100 this time.
If it is 1, the rising state change data is 1000 according to the above promise.
Since it becomes 001 and is not zero, the state change data section 82 contains 11.
Store 010001 (STOR), status data section 8
1 is now vs notator 110010011! Payment (51
TOBEt).

However, in this case, if the status data section 81 is 0101 last time
1100 and this time it is 01001000, the start-up state change data is ooooooooo 01
3- Therefore, the process jumps to point P, only stores the current data 01001000 in the status data section 81, and proceeds to point Q.

Now, when you turn on the status change manual switch, it is convenient to operate if the lamp lights up to make it easier to identify, so if the status change data is not zero at the start, perform @ BTORTA, and then turn on the indicator lamp corresponding to the status change switch. the hardware (
It is determined whether the process is to be performed by the control device 31 alone (independent of commands from the host control device 1) or by software (commands from the control device 1) (HAD). The enlarged view of the hardware/software lighting classification table 711 in FIG. 7 is for this purpose, and if the bit in the table is "l", the light is turned on by the hardware. Defines output to the specified device.

For example, in Fig. 7, the switch input serial number LODN8 is x
Since the content corresponding to "@oo" is X"ii'F", that is, all 8 bits are "1", this indicates that the light should be turned on by the hardware (proceed to H in Figure 13), so the control device l
In addition, LODN8 in Fig. 9 is x”o
Since the content corresponding to "o" is X114-201, 8-bit data is written to the output circuit with the output serial number LODNO of X"20@ using only the multifunction control device 31. This entry is X”2 as LODNO
This means that the command is executed (LOUT) by converting to a physical machine @ (PHDN) according to the contents of the output conversion table 717 in FIG. 6 using "0" as a key. Then, proceed to R.

In Figure 7, the content where LODN8 corresponds to
Therefore, what should be lit by software (No. 13)
(Proceed to point 8 in the figure), so a command from the control device 1 is required, but here the control device 31 does nothing and proceeds to point 8. Detailed processing is left to the upper control device 1, and display processing is performed when a display command is received from the control device 1 later.

At point 8, an interrupt signal is transmitted to the control device 1 (T
IRfi coral) Proceed to point Q. The 8-bit data in the rising state change data @82 and the state change switch input serial number LODN8 are referred to as necessary during the ROUT processing described later.

At point Q in FIG. 13, LODN8 shown in FIG. 5(b) senses the switches corresponding to X"IO" to 1171 (880 process in FIG. 13). This is flew
It can be seen from Figure 3112 that it is a switch. This switch information is made up of n bits as one block, of which only one bit is exclusively selected and has a meaning, and the base is designed such that an integer multiple of 8 can be selected. Figure 8 is n
ET Switch Input Input - Table Previous Blocks and LO
This shows the relationship with DN8. The LODN8 for the 0th bit is X"IO", and the LODN8 for the 1st bit, 2nd bit, etc. is X"l, respectively.
If it is defined as ``1'',
As X"IO@, the 1.2nd bit is '11' in the second block, that is, LODN8 as X"ll", X"
121, but the 3rd to 6th bits are “1” in the third block.
In other words, X"13" to 116" are LODN51,
In the fourth block, only the 7th bit is “1#”, that is, L
Since X"17" is included as ODN8, nc* is checked only for the 8 bits in the input sequence number X"IO" for the tuna 1 block, and for the tuna 2 block, X"
This shows that a total of 16 bits in the input sequence numbers ``11'' and ``12'' should be considered.
) as the corresponding PHDN:
Reading about 97″ - roar. I will omit explanations about other blocks.

The new IC1 switch information obtained in this way is compared with the nC and switch information read during the previous round of task TK, and if they are the same, or if the new nc+switch information is zero, the previous output state In order to maintain this, the process returns to point T without doing anything, and if it is different, the new information is checked flc1 and then outputted by the hardware according to the new information (not based on the command from the control device 1, but only by the control device 31).

This can be seen in Figure 7 as LODN8
~ “Hard and soft lighting identification for 17° Even if it is not specified, it is not necessary if it is specified that the hard lighting will always be lit, but it would be more convenient if it was specified.And LODN8 shown in Figure 9 The output is performed by hardware using the fact that the output serial numbers LODNO corresponding to X"IO' to 117I are X"30"-"37".

17- When the T point is reached, the presence or absence of a command from the control device 1 is checked, and if there is no command, the process proceeds directly to \RNT, and if there is, command identification processing (RJIN) and corpse processing (ROUT) are performed. The contents of the command are R11lAD and WRITIi.
There is. From the control bag [1 onwards, information is added in addition to commands, but as already mentioned, there are two types of input sequence numbers: switch input sequence number LODN8 and information input sequence number LODND. The latter is not based on the commands of the upper control device! This is due to the Karame Directive.
Both are number 5! Il! (1), Figure 5 (X'' as in bl)
The accesses to LODN8 and LODND are distinguished by different execution command codes such as "DB" and "Dm". Therefore, by reading the information input sequence number LODND, the information sent from the control device 1 is added. control bag [3
It is possible to diversify the functions on the first side.

Taking the relay output as an example for the ROUT process mentioned above,
There are two types of output: holding type and instantaneous (or pulsed) output.
The enlarged view of the instantaneous hold output distinction table 714 in Figure 10 of Volume 10 shows the output mode, and the contents of the address corresponding to LODNO is 18-X"4F" and "52" are "O".
O'', which indicates the holding output and also LODNO
But X"50", "51" IC Mukuro! The content of the address to be output is 1011, which means that if instantaneous output is specified, the output sequence number LODNO will be determined by the combination of command information and additional information sent from the control device 1. Check the output mode of the scissors output serial number, and if it is a holding output, only the relay output is performed, and if it is the instantaneous output, after the relay output is performed, start the T1 timer 15 for a fixed time and Ff respectively.
Proceed to NT.

In this case, specify a fixed time T, issue a command to start the timer 15, proceed to BNT, perform the prescribed procedure, and after the processing cycle, start the timer 15 again and compare it with the time To. If T+ < To, the relay output is opened when the set time has elapsed and the pulse operation is completed. On the other hand, T)
If T., the timer 15 will be started again before the set time elapses, and the timeout of the fixed timer 15 will be extended. In other words, the pulse duration becomes longer. As long as time postponement is repeated in this way, the timer 15 will not time out, no signal will be generated, and the task T
Since K does not start, the relay does not open and continues to be on.

For this reason, it is necessary to manage the time for each relay output bit so that the relay can be opened after an appropriate amount of time has passed, but this management is too complicated, so there is a method that allows the control device 1 to manage the timing of command generation. Good! Yes.

Next, a description will be given of a lamp lighting mode, that is, an output method in which continuous flicker ON mode pits are mixed at the same 8-bit location. This output also lights up the hardware,
This can be done by either software lighting, but here we will use software lighting, that is, WR from the control device l.
A case using an ITI command will be explained.

P the output device of LODNO x”001~IoP1
If it is shown in HDN, it is x “go” ~ @8F1, t LODN
It can be seen from Figure 6 and Figure 12 that if O represents the output device of , the output device with PHDN x"go" ~ "8F" is connected to the flicker output converter 22, and the PHDN
Connect the output device whose DN is X"oo@~"OF" to the on/off output converter 21, input the information via the address bus 24, data bus 25, and control path 23, and connect the two converters. The output is output (OUT) in a bit-wise OR connection.

According to the allocation that has been described so far, when the flicker output sequence number is expressed as Y, if X "10" is added to this, the on-off output sequence number 2 is obtained, and conversely, when the on-off output sequence number is expressed as 2. , by subtracting X "10" from this, the flicker output serial number Y can be obtained. Since flicker is considered to be a special case of continuous ON, if we take the bit-corresponding OR output of the flicker output converter 22 and the ON/OFF output converter 21, it is clear that the OR output has priority over the flicker output for each bit. If a flicker bit and a continuous ON bit coexist within the same location of an 8-bit configuration, *"c also performs the following processing to give priority to flicker.

In other words, to output data Dc to on/off output serial number 2 and output data DF to flicker output serial number Y (=Z+X@lO") while outputting data Dc in a superimposed manner, set data Dc to 1.
0110111, assuming DF is 11000100, output DF (11000100) to flicker serial number Y, create complement N (00111011) of Dv, Dc
(10110111) and DF, Dc'(
Complete by creating Qollooll) and outputting Da' to output sequence number 2.

While DF is being output to flicker output serial number Y, in order to give data Dc to on/off output serial number Z (=7-X"lG") and output both in a superimposed manner, first assume that data DF is 11000100 and data Dc is 10110111. Leave the serial number Y output as is and complete the process by following the procedure described above.

Output to the output serial number is performed by expanding the output to the physical machine number using the conversion table described above, and flicker,
Mode combinations such as continuous ON and OFF, duration 1
Illustrator and others are not skilled enough to tell you that it is sufficient to appropriately synthesize output commands into a standard 22-timer subroutine.

According to the present invention, a microprocessor, ROM, RAM, and transmission circuit are provided in the operator console control device provided between the operator console and the host control device.

An input circuit, an output circuit, and a fixed-time timer are provided, and a task is activated by taking the signal generated when the fixed-time timer times out as an interrupt request to the microprocessor, and a processing task with a lower priority than this task is prepared. The state change switch input data, rising state change data, output buffer, and control table are stored in the RAM, and this control table includes a hard and soft lighting identification table, rl
In addition to CI information tables, switch input tables, instantaneous and held output distinction tables, input conversion tables and output conversion tables that store commands to be executed by converting input/output serial numbers to physical machine numbers are also stored, allowing operator console control. The l device transmits input/output serial numbers and data to a higher-level control device such as a computer and an input/output circuit, and the higher-level control device transmits input/output serial numbers and data to an operator console control device to control input/output circuits. It is possible to create processing tasks in the operator console system @et without being aware of the physical machine number. Addition or deletion of input/output circuits can be handled by simply rewriting the conversion table, reducing design, manufacturing, and testing man-hour costs.
It is possible to create a highly maintainable system.
