ExplicitMessage
An Explicit message is a point-to-point, request/response-type communication.
Communication using Explicit messages are only supported for PCCC.
SystemConfigurationonPLC
Use the configuration tool to code an Explicit message as an MSG instruction in the
control logic. In the MSG instruction, set all the information including a target device,
target register, and read/write. Download the created control logic to a PLC and execute
it.
On the recorder the data count to be accessed per MSG instruction should be 100 or less.
