E5ZE Temperature Controller Read Protocol

The E5ZE Temperature Controller Read Protocol reads and controls various parameters in remote mode for the

Temperature Controller connected to the Serial Communications Board via RS-232C or RS-422A/485 cable.

Note 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., DM 0000) address for the 3rd operand (D).
