Appendix J
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.
Note 1. The hexadecimal equivalents of sequences numbers are given in parentheses.
2. Ladder Interface Settings
YES: User settings are required for the 3rd or 4th operands of PMCR.
NO: Send word allocation: Set the constant 0000 for the 3rd operand (S).
Receive word allocation: Set the constant 0000 for the 4th operand (D).
