Also, when the transmission / reception data amount greatly differs depending on the transmission / reception units 31-1 to 31-n, a configuration is known in which the transmission / reception control unit 34 controls the allocation of the area of the memory 32 in accordance with the transmission / reception data amount. ing.

In the transmission frame format of the CDT system, for example, one cycle is made up of two frames, one frame is made up of 32 words, and one word is made up of 44 bits. The 22 bits including the flag, parity check, data, etc. are inverted and transmitted in a 44-bit configuration. On the receiving side, the 22 bits in the first half and the 22 bits in the latter half of one word are inversely collated in bit correspondence. In addition, the transmission error is detected by using the parity check bit.

The transmission data area MA and the reception data area MB store the transmission data and the reception data by the areas corresponding to the line number or the transmission / reception unit number. Since the CDT system has a fixed frame length, the data area corresponding to the line (corresponding to the transmission / reception unit) can be set as a fixed length.

The response setting area MC is, for example, 2
It consists of a response effective length part having a word structure, a command type part having a three word structure, a transmission / reception type part having a one word structure, a display / setting part, a completion information part, and a reserve part. The command setting area MD of the memory 22 is different in that the completion information part of the response setting area MC is the setting value part. The command setting area MD and the response setting area MC may have a configuration of items corresponding to the configuration of the transmission / reception device 16.

When the accessory device 20 is connected to the transmission / reception device 16 by the connection cable 18 and a command, test data and the like are input from the keyboard 26, the processor 21 controls it to set it in the command setting area MD of the memory 22.
The command type section of this command setting area MD is set with the type of test or monitoring, the area designation of the memory 12 of the transmission / reception device 16, and the like, and the transmission / reception type section monitors transmission data or reception data. The transmission / reception type is set, the display / setting unit is set with information on whether to set test data or the like or the data to be monitored is displayed, and the setting value unit is set with test data or the like. The reserve section is an area provided to allow the function of the accessory device 20 to be expanded. Further, the effective length of the command is set in the command effective length section.

After all the settings in the command setting area MD are completed, the execution key of the keyboard 26 is pressed, for example. As a result, the processor 21 causes the command setting area M
The contents of D are read and transferred from the input / output interface unit 23 to the transmission / reception device 16 via the connection cable 18.

The transmitting / receiving device 16 analyzes the contents received from the command setting area MD via the input / output interface unit 15, and when performing a transmission test with a test command, the transmission / reception unit number or line number for which the test data is designated. The data is set in the transmission data area MA of the corresponding memory 12, the transmission control to the opposite device is performed, the return data or the response information is received from the opposite device, and the result is set in the response setting area MC. When performing a reception test with a test command, the test data is set in the reception data area MB of the memory 12 corresponding to the specified transmission / reception unit number or line number, and the reception processing result by the processor 14 is set in the response setting area MC.

Is read. The read data is transferred to the auxiliary device 20, or the result of the read is determined and set in the response setting area MC, and the normal end or abnormal end is set in the completion information section.

The setting contents of the response setting area MC are controlled by the processor 14 and the input / output interface unit 15 is used.
Is transferred to the auxiliary device 20. The processor 14 of the accessory device 20 determines the content of the response setting area MC, and displays the result on the display device 27 or prints it out by a printer (not shown).

FIGS. 4 and 5 are flowcharts of the embodiment of the present invention. On the side of the accessory device 10, data is input from the keyboard 26 (1), and a command according to the input contents is created. (2). That is, in the command setting area MD shown in FIG. 3, the command valid length section, the command type section, the transmission / reception type section, the display / setting section, and the set value section are set. Then, the command setting area M is controlled by the processor 21 according to the pressing of the execution key or the like.
The command read from D is transmitted from the input / output interface unit 23 to the transmission / reception device 16 (3).

Along with this command transmission, a transmission timer is started (4), and when a response cannot be received even if a preset time has elapsed, in order to time out and process,
It is determined whether it is time-out (5). If it is not a time-out, it is judged whether or not the response is received (6), and if the response set in the response setting area MC of the transmission / reception device 16 is received, the received data is analyzed (7), and the content is normal. (8),
If it is normal, the data is displayed on the display device 27 (9). In the case of an abnormality, the abnormal termination is displayed on the display device 27 (11). When the time is out, the result is displayed on the display device 27 (10).

On the transmitter / receiver 16 side, it is judged whether or not a command has been received (21). If a command has been received, that command is analyzed (22), and that command is stored in the memory 1
It is determined whether or not the data of No. 2 is read (23), and if the data is read, the data is read from the memory 12 (2
6). For example, in the case of a command for monitoring transmission data, the transmission data is read from the transmission data area MA of the memory 12 corresponding to the transmission / reception unit designated by the command. In this case, the start address of the transmission data area MA of the memory 12 is calculated based on the line number or the transmission / reception unit number, and the transmission data is read.

If the data is not read, it is determined whether the data is set (24). If the data is set, the data is written in the memory 12 (25). For example, in the case of a test command, the test data to be transmitted is written in the area corresponding to the designated line number or transmission / reception unit number of the transmission data area MA of the memory 12. If the data is not set, it is determined whether the setting is canceled (27). If the setting is canceled, the setting of the memory 12 is canceled (28).

Then, the processor 14 determines whether or not the process is normally terminated.
Is judged (29), if it is normal end, a response is sent as normal end (30), and if it is not normal end,
A response is transmitted as an abnormal end (31). That is,
In the response setting area MC shown in FIG. 3, a response valid length portion, a command type portion indicating a test command or a monitoring command, a transmission / reception type portion indicating transmission data or reception data, or a case of displaying on the display device 27, or A display / setting section indicating whether the test data is set, a completion information section indicating normal end or abnormal end, and the like are set, and transferred to the auxiliary device 20 under the control of the processor 14.

Therefore, by connecting the input / output interface unit 23 of the accessory device 20 and the input / output interface unit 15 of the transmitter / receiver 16 with the connection cable 18, and inputting a command or test data from the keyboard 26 or the like. , Testing and monitoring can be performed corresponding to the transmission / reception units 11-1 to 11-n. That is, since it is not necessary to change the connection of the auxiliary device 20 and the normality of the transmission data and the reception data can be confirmed by reading the contents of the memory 12, the lines 17-1 to 17-n can be confirmed. It is possible to monitor without setting the transmission speed.
