Commands and Responses

 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.

Response

Error response

*1 The data length is different depending on the data being read. (Up to 10 characters)

*2 SK-1000: ±**.*** (reading range is -99.999 to +99.999)

*3 Data length: 2 characters

On the SK-1000 Series, the judgment output (HI/LO/GO output) and the alarm output ON/OFF

are displayed with 2-digit number (ASCII characters). Convert the 2-digit number (ASCII

characters) read to a binary number and check the ON/OF status of each bit to check the

judgment output status.

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).
