Communications Sequence - Omron E5 D Series Connection Manual

9.2. Communications Sequence

The following describes the communications sequence that is used for the PMCR instruction
in this program.
9.2.1. Communications Sequence Number
A communications sequence that is registered in the SCU is identified by a communications
sequence number. The Destination Device executes the command corresponding to the
communications sequence number that is specified in the program for executing the PMCR
instruction.
The protocol data used in this guide includes the following communications sequence.
No. Command name
618 Properties Read
9.2.2. PMCR Instruction Operand Settings
