Appendix G
E5@K Digital Controller Write Protocol
The E5@K Digital Controller Write Protocol writes and controls various settings in remote mode for the Control-
ler connected to the Serial Communications Unit/Board via RS-232C or RS-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@K Digital Controller Write 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.
