To do this, a cathode ray tube display device, a printer, etc. are usually used.

[Problem that the invention seeks to solve]

However, standard keyboards, cathode ray tube displays, etc. are large and expensive, and can only be used by being fixedly installed in a certain location, and it is uneconomical to install them for each control device etc. installed in a distributed manner. In addition, in order to provide a relatively large amount of data to a control device, etc., a tape reader, cart reader, etc. must be provided separately, resulting in an overall high cost.

[Means for solving problems]

In order to solve the above-mentioned problem, the present invention is constructed by the following means.

That is, a memory card read/write circuit, a keyboard, a display section, a connection means that can be detachably connected to a data transmission path, and a connection means that is connected to the memory card according to the operation of the keyboard and the contents of the memory card via the read/write circuit. The device includes a data processing unit that transmits and receives data to and from a data transmission path and displays the received contents on a display unit, and a handheld housing that houses these parts as one unit.

[Effect]

Therefore, a large amount of data can be given to the memory card, the data can be freely changed by exchanging it, and data can be transmitted in response to keyboard operations and the contents of the memory card, giving commands to the desired device. and data settings, and the content of the received data can be displayed on the display unit.

Even if the data transmission speed with 11 to 1n etc. is different, the GW 7 relays the data mutually, and if the commands from the MCT 5 cannot be received due to a failure in the MCT 5 or the main data transmission line 6, the time G functions such as schedule control
W7 takes over and does not interfere with the control operations of BCT 1 + to 1n, etc.

Therefore, the BCTs 11 to 1n etc. perform local control based on the basic control data given from the MCT 5, and transmit this status to the MCT 5.
In CT 5, general control status settings, changes,

It executes the instructions and performs data processing operations while accessing necessary data to the RAM 92.

Therefore, depending on the operation of the KB55, the memory card 56
The contents of the memory card 56 are stored in the RAM 92, and the contents of the memory card 56 can be freely set or changed by operating the KB 55. These conditions are displayed on the DP 54.

Also, by operating the KB 55, the contents of the RAM 92 or memory card 56 are transmitted as transmission data, and a response thereto is received and displayed on the DP 54, so commands to each unit, data settings or changes, or , the contents of the memory card 56 can be transferred, these can be confirmed by the DP 54, and the data to be confirmed can be requested to be sent to a specific unit, and the received contents can be transferred to the RAM 92 or the memory card 56. In addition to being stored, the data can be displayed sequentially by the DP 54.

In addition, it is possible to freely receive and display data signals.
This makes it possible to monitor the status of data transmission and reception between each unit.

FIG. 4 is a flowchart of the processing operation by the CPU provided in the MCP91 of Ranko 8. If the ``key manual pusher? Judgment: N (NO)
In this case, drive DP 54 and select "Display key human power" 203
, and repeat steps 201 and subsequent steps.

Also, when step 202 is Y, if the content of step 201 is “Y of communication processing A, 9? J211, then I/
``Transmission processing'' 221 via F 96 and CN 59 is performed, and a corresponding ``reception processing'' 222 is performed, and the DP 54 is driven according to the received content to perform ``result display'' 223, and then step 201 "Key power is monitor?J231" is judged, and if this is N, it returns to step 201, whereas when step 231 is Y, it further checks the new "key power is monitor?J24x" and determines the N of this. As a premise, "timer processing" 242 is performed, and step 22 is performed at a fixed period determined by this.
Repeat the steps from 1 to 0. If step 241 becomes Y between 0 and 0, in response to this, "Display key human power" 251 as in step 203.
and returns to step 202.

Regarding the above, when step 211 is N, step 2
01 is ``L/G switching?J'' 261 is judged, and depending on this Y, data is sent and received only with the connected unit ``L'', or rGJ is sent and received in general via data transmission path 3 "L/G switching processing" 262 is performed to repeatedly select the
P 54 is activated to perform ``display processing results'' 263, and the process returns to step 201.

Note that initially it is in the rGJ state, and step 26
2, rLJ and rGJ are alternately selected, and the data transmission/reception status in steps 221 to 223 is determined accordingly.

Further, if step 261 is N, step 201 determines "Card RAW? J 271, and depending on this, reads the contents from the memory card 56 via CEW 95 or writes data to the same card 56.""Card R/W processing" 272 is performed, and "processing result display" 273 is performed in the same manner as step 263.

On the other hand, if step 271 is also N, step 201 determines "Other processing? J281", performs "other processing" 282 in accordance with Y of this, and displays "result display" 283 of this on DP54. However, if steps 261, 271, and 281 are all N, step 201 is an erroneous operation, and 9. DP54 is driven to display "error display of no applicable process" 291, and return to step 201. .

Therefore, in response to Y in step 271, the contents of the memory card 56 are stored in the RAM 92, and the KB 5
5, the contents of the memory card 56 can be freely set or changed, and the status of these settings is displayed on the DP 54.

Further, in step 211, Y, the contents of the RAM 92 or data corresponding to the operation of the KB 55 are transmitted, and a response thereto is received and displayed on the DP 54, while in step 241, N, these data are transmitted. The operation is repeated at a certain period, and this situation is DP
54, commands to each unit, data settings or changes, program settings by transferring the contents of the memory card 56, file creation, self-diagnosis commands, etc. can be given to each device, and By being able to check these conditions using the DP 54, it is possible to provide various data to each device without having to equip the HMMI 8 with a large capacity memory.

On the other hand, in response to Y in step 231, only the reception of the data signal on the data transmission line 3 and the display thereof are repeated one after another, so it is possible to monitor the status of data transmission and reception between each unit.

However, the configurations in Figures 3 and 1 can be arbitrarily selected depending on the situation, and in Figure 4, each step can be replaced with an equivalent one, or the order can be changed or , unnecessary steps can be omitted, and various modifications are possible, such as being able to connect to various data transmission paths in addition to the configuration shown in FIG. 2.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, operation and display can be performed with a simple and inexpensive configuration, and it is also possible to optionally provide a large amount of data to a control device etc. by using a memory card. In addition, since the entire device is small and lightweight, it is convenient to carry and provides remarkable effects in operating and displaying various control devices, data processing devices, etc.
