E5@J Temperature Controller Protocol - Omron CQM1H-SCB41 Operation Manual

E5@J Temperature Controller Protocol

The E5@J Temperature Controller Protocol performs various settings and controls in remote mode for the Tem-
perature Controller connected to the Serial Communications Board via RS-232C or RS-422A/485 cable.
Note Negative values cannot be written. All values must be set as unsigned BCD.
