E5@K Digital Controller Write Protocol - Omron CQM1H-SCB41 Operation Manual

E5@K Digital Controller Write Protocol

The E5@K Digital Controller Write Protocol writes and controls various settings in remote mode for the Control-
ler connected to the Serial Communications Board via RS-232C or RS-485 cable.
Note Negative values cannot be written. All values must be set as unsigned BCD.
Structure of the Protocol
The following table shows the structure of the E5@K Digital Controller Write Protocol.

Note Ladder Interface Settings
YES: User settings are required for the 2nd or 3rd operands of PMCR.
NO: Send word allocation:
Receive word allocation: Set a dummy word (e.g., DM 0000) address for the 3rd operand (D).
