K Es100@ Digital Controller Protocol - Omron SYSMAC CS1W-SCB41-V1 Operation Manual

The ES100@ Digital Controller Protocol controls in remote mode and reads various settings from the Controller
connected to the Serial Communications Unit/Board via RS-232C or RS-422A/485 cable.
Note Negative values cannot be written. All values must be set as unsigned BCD.
