Appendix F

E5ZE Temperature Controller Write Protocol

The E5ZE Temperature Controller Write Protocol writes and controls various settings in remote mode for the Tem- perature Controller connected via a RS-232C or RS-422A/485 cable from the PC via the Serial Communications Board.

Note 1. Negative values cannot be written. All values must be set as unsigned BCD.

2. All sequences in this appendix operate on memory bank 0 and cannot be used for other memory banks.

Note Ladder Interface Settings
YES:	User settings are required for the 2nd or 3rd operands of PMCR.
NO:	Send word allocation:	Set the constant 0000 for the 2nd operand (S).
	Receive word allocation:	Set a dummy word (e.g., DM0000) address for the 3rd operand (D).
