DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. This does not limit the invention. FIG. 1 is a block diagram of a composite exchange system showing an embodiment of the present invention.

Reference numeral 11 is a command board having a plurality of input keys and a plurality of display lamps, 12 is a control package (control device), 13a and 13b are interface packages (interface devices), 14a and 14b are various devices, and 20 is a command. A terminal board that relays the multi-core cable C11 that connects the base 11 and the control package 12 is a terminal board that relays the multi-core cable C12 that connects the control package 12 and the interface packages 13a and 13b.

The control package 12 is SCAN.
Processing unit 18, operating program processing unit 15, test program processing unit 17, SD processing unit 19, and switch 16
Is equipped with.

With respect to the composite exchange system having such a configuration, first, the normal operation will be described. The “operating mode” is set by the switch 16. Then, when the input key of the command board 11 is operated, the key information S1 corresponding to it is output. The key information S1 is so-called scan information (SCAN information) composed of a serial signal.

The key information S1 output from the command board 11 is signal-processed by the SCAN processing unit 18 and input to the operation program processing unit 15. The driving program processing unit 15 that receives the key information generates information corresponding to the key information based on the preset driving program and inputs the information to the SD processing unit 19.

The SD processing section 19 converts the information into so-called SD information (parallel information represented by 0V and 5V),
It is output as control information S2. The interface package 13a or 13b that has received the control information S2 from the SD processing unit 19 receives the various devices 14 based on the control information S2.
While controlling a or 14b, the response information (SCAN information) S3 corresponding to the control information S2 is returned to the SCAN processing unit 18 of the control package 12.

The response information S3 is signal-processed by the SCAN processing unit 18 and input to the operation program processing unit 15. The driving program processing unit that receives the response information generates information corresponding to the response information based on the preset driving program and inputs the information to the SD processing unit 19.

The SD processing section 19 converts the information into SD information and outputs it as lamp information S4. The command board 11 receiving the lamp information S4 from the SD processing unit 19 turns on the lamp corresponding to the lamp information S4.

Next, the test operation will be described. First, the switch 16 sets the “test mode”. Then, when the input key of the command board 11 is operated, the key information S1 corresponding to it is output.

The key information S1 output from the command board 11 is signal-processed by the SCAN processing unit 18 and input to the test program processing unit 17. The test program processing unit 17, which has received the key information, generates information corresponding to the key information based on the preset test program, and generates S
Input to the D processing unit 19.

The SD processing section 19 converts the information into SD information and outputs it as control information S2. SD processing unit 19
The interface package 13a or 13b that has received the control information S2 from the above returns the response information (SCAN information) S3 corresponding to the control information S2 to the SCAN processing unit 18 of the control package 12.

The response information S3 is signal-processed by the SCAN processing unit 18 and input to the test program processing unit 17.
The test program processing unit, which receives the response information, compares the key information and the response information with each other using a preset comparison table, generates information corresponding to the comparison result, and inputs the information to the SD processing unit 19.

The SD processing section 19 converts the information into SD information and outputs it as lamp information S4. Upon receiving the lamp information S4 from the SD processing unit 19, the command board 11 turns on the display lamp corresponding to the lamp information S4.

That is, the test program processing section 17 in the test mode compares the key information S2 with the response information S3 each time the input keys of the command stand 11 are sequentially operated, and the result of the comparison is indicated by the display lamp of the command stand 11. To display.

Therefore, the operator can easily know the quality of the connection between the control package 12 and the interface package 13a or 13b from the relationship between the input keys and the display of the display lamp.

[0028]

According to the present invention, the connection status between the control device and the interface device is displayed on the display lamp by the operation of the input key, so that the connection confirmation work can be performed only by the command board and is extremely simplified. .
