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 Unit/Board via RS-232C or RS-422A/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#J Temperature Controller Protocol.
