FIG. 1 shows a functional block diagram of an embodiment of the present invention. In FIG. 1, 1 is an application unit, 2 is a transfer control unit, 3 is a data link control unit, 4 is a man-machine interface, 5 is a system generation file, 6 is a sequence file, and 7 is a data file containing test data. ..

The application unit 1 activates the secondary station, that is, establishes a data link between the simulated terminal and the communication control device, edits data, and performs man-machine interface control. The transfer control unit 2 is composed of a transfer control program, controls the communication protocol between terminals, and controls a plurality of SAs (Statio
n Address Station address) is controlled individually. Here, SA is a unique address in the line and has a one-to-one correspondence with the terminal simulated by the man-machine interface. The data link control unit accesses the line according to the transmission control procedure and connects to a communication control device (communication control device) not shown. The connection of the devices that realize these functions is shown in the block diagram of FIG. In FIG. 2, reference numeral 21 is a computer, which is an application unit 1 and a transfer control unit 2 in FIG.
Also, the data link control unit 3 is realized. Reference numeral 22 is a personal computer representing the man-machine interface 4 in FIG. 1, and 23 is a line printer.

FIG. 3 shows an example of a network configuration to which the present invention is applied. 41 is a communication control device, 42 is a communication control device 4
It is a simulated terminal viewed from 1, and has the functions of the application unit 1, the transfer control unit 2 and the data link control unit 3 of FIG. Reference numeral 43 is a loop outlet, which connects the loop line from the communication control device 41 and the simulated terminal 42. Reference numeral 44 is a console realized by the personal computer in FIG. 2, and 45 is a line printer. The communication control device 41 and the simulation terminal 42 are connected and operate as follows.

The operation of this simulator will be described with reference to the flow chart of the application section processing in FIG. When started, the application unit 1 reads the system-generated file (SG file) 5 specified by the system information (step P1), and registers the SA and the number of SAs described therein in the transfer control unit 2. , The resources are secured (step P2), and the SA number of data links are set (step P3). It is judged whether or not it is completed (step P4). When it is completed, a startup message is output to the console constituting the man-machine interface 4 (step P5), the operator is notified and the input command is waited (step P6). .. If it is determined in step P4 that the processing has not been completed (NG), the startup NG message is output, the processing up to this point is invalidated, and the subsequent processing is rejected (step P7). In Step P6, the operator inputs a command from the console to simulate and operate as a terminal to which an arbitrary SA is assigned. At this time, the input command includes a network join command distinguished as a terminal of a different SA by the communication control device 41 in FIG. 3, and this is stored by the communication control device 41. The application unit 1 in FIG. 1 analyzes the command input for each SA (step P8), reads and executes the sequence file 6 and the data file 7 of the terminal to be simulated, and sends a transmission request to the transfer control unit 2. (Step P9). In FIG. 1, the transfer control unit 2
Performs protocol processing of the transmission request from the application section 1 and sends it to the data link control section 3. The data link control unit 3 controls the data transmission to the communication control device 41 in FIG. 3 through the line according to the transmission control procedure and controls the data reception from the communication control device 41 to transfer the confirmation notification report to the transfer control unit 2 Send to. The transfer control unit 2 performs protocol processing of this signal and sends it to the application unit 1. The application unit 1 notifies the man-machine interface 4 of the transmitted data or reads necessary data and executes the data. When the simulation is completed for one terminal, the process returns to step P6 of FIG. 4, commands for other terminals are input from the console, and thereafter, the transfer control section 2 and the data link control section 3 are similarly executed by executing steps 8 to P9. Also, a predetermined operation of the communication control device 41 can be performed, and a plurality of terminals, that is, the number of SAs can be simulated by one simulation device, and the communication control device 41 can be tested. When the simulation is performed for the number of SAs, the processing of the application unit 1 in FIG. 4 ends.

In the above description, the application section 1
The repetitive sequence etc. read by can be made into a file, and the operation can be simplified by inputting the sequence file from the console. Further, if the SA is different, even if there is a sequence being executed, it is possible to change and specify the execution number of the sequence and specify the sequential file to execute.
This enables simultaneous data communication of a plurality of terminals.
Further, since the test data file and the like can be easily changed, it is possible to flexibly deal with any system.

[0012] Normally, the data link control unit has the station address (SA) of the secondary station, that is, the terminal fixed (stored) as one station.
Stores a predetermined number of SAs for a plurality of terminals and can interface with a host (application unit) so that a plurality of SAs specified by the host (application unit) can be recognized.
