Commands and Responses



Read output states and data from all sensor amplifiers (MS command)

Command

Response

Error response

 Read with external input to the DRQ terminal (DRQ read)

You can send an input signal (by short-circuiting DRQ (terminal number 6) and SG (terminal number

1, 4, or 5)) from an external device such as a PLC instead of sending a command.

Commands and Responses

Writing

External devices such as PLC's use the following communication commands to write data to

DL-RS1A.

Attempting to write data with "read-only" attribute results in a communication error and an

error response (error number: 22).

■ Write to the specified sensor amplifier (SW command)

Command

Response
