FIG. 12 is a flow chart for explaining the operation of the CATs 2a and 2b shown in FIG. Next, the operation of the CATs 2a and 2b will be described in detail with reference to FIGS.

First, the CPU 20 of the CAT 2 displays on the display 22 that the business key 31 should be operated, and waits until the business key 31 is operated. When the business key 31 is operated, the CPU 20 performs a process according to the key input, and particularly when the other key 315 is operated, subsequently, a message indicating that the classification code should be input is displayed, and the classification code is displayed. Will wait for input.

The operator operates the first host computer 3 from the first host computer 3 to the cluster controller 1
To request DLL to
For example, "90" is input, and then the set key is pressed. When the cluster controller 1 requests the cluster controller 1 to DLL the CAT 2, the numeric keypad 32 is used to input, for example, "91" and then the set key is pressed. Also, the CAT
2 is provided for, for example, a tenant,
The operator sends a DL to the second host computer 4.
To request L, the user inputs "92" from the ten-key pad 32 and then presses the set key.

When "90" is input, the CPU 20 causes the display 2
2 indicates that processing is in progress, and the terminal number data and keyboard 23 stored in the terminal information storage area 273 are displayed.
A DLL request message 60 for requesting the transmission of data from the first host computer 3 to the cluster controller 1 is created based on the data keyed in from and is transmitted to the cluster controller 1. Then, the CPU 20 waits until the processing result is transmitted from the cluster controller 1. In response to receiving the processing result message 50, the CPU 20 prints the processing result by the printer 21, displays it on the display 22, and returns to the initial state.

When "91" is input, the CPU 20 causes the display 2
Displaying that it is being processed in 2 and doing the same as above,
A DLL request message 60 for requesting transmission of data from the cluster controller 1 to the CAT 2a is created based on the terminal number data stored in the terminal information storage area 273 and the data keyed in from the keyboard 23.
Send to cluster controller 1. Then, CPU2
0 waits until the DLL message 70 is received from the cluster controller 1. In response to receiving the DLL message 70 from the cluster controller 1, the CPU 20 stores the content of the message in the RAM 27, subsequently prints the processing result by the printer 21, displays it by the display 22, and returns to the initial state. .

When "92" is input, the CPU 20 displays the fact that processing is in progress on the display 22 as in the above description, and the terminal number data stored in the terminal information storage area 273 and the key input from the keyboard 23 are performed. A DLL request message 60 for requesting the transmission of data from the second host computer 4 to the CAT 2b is created based on this data and is transmitted to the cluster controller 1. Then, the CPU 20
Stands by until a DLL message similar to the DLL message 70 is transmitted from the cluster controller 1. In response to receiving the DLL message from the cluster controller 1, the CPU 20 stores the DLL data in the RAM 27, prints the processing result by the printer 21, displays it on the display 22, and returns to the initial state.

FIG. 13 is a flow chart for explaining the operation of the cluster controller of the embodiment of the present invention. Next, the operation of the embodiment of the present invention will be described in detail with reference to FIGS.

The CPU 10 of the cluster controller 1 is CAT 2a, 2
b, waiting until receiving a message from the first host computer 3 or the second host computer 4,
In response to receiving a telegram from the first or second host computer 3 or 4 via the upper transmission unit 14, the received telegram is associated with the corresponding C via the lower transmission unit 15.
Although it transmits to AT2a, 2b, when the electronic message from CAT2a or 2b is received, it is judged whether the transaction classification code contained in the received electronic message is "5" which shows the other key 315. When the CPU 10 determines that the transaction classification code is not "5", it sends the message from the CAT 2a or 2b to the corresponding first host computer 3 or second host computer 4. On the other hand, if it is determined that the transaction classification code is "5", then the classification code is "90" or "91".
2 "is determined.

Here, if the classification code is "90", the CPU
10 transmits the DLL request message 60 transmitted from the CAT 2a to the first host computer 3. Next, CP
U10 is a DLL message 7 from the first host computer 3.
It waits until 0 is received, and when the DLL electronic message 70 is received, its contents are transferred to the RAM 12 and stored. Then, the processing result is transmitted to the CAT 2a, and the state is returned to the initial state.

When the classification code is “91”, the CPU 10 makes R
DLL message 7 based on the data stored in AM12
0 is generated, and the CAT2a is transmitted via the lower transmission unit 15.
To the initial state.

When the classification code is “92”, the CPU 10 C
The DLL message 60 from the AT 2b is transmitted to the second host computer 4 as it is. Subsequently, the CPU 10 uses the second
The host computer 4 waits until the DLL message is transmitted, and when the message similar to the DLL message 70 is transmitted from the second host computer 4, the message is transmitted to the CAT 2b as it is, and the initial state is set. Return.
