9 Parameter data transfer (explicit messages)
An "explicit message" is a logical instruction in the PLC program used for messaging. It can be used
to read or write to either a parameter setting or the data of an assembly object.
For all Allen-Bradley devices of the CompactLogix, ControlLogix and SoftLogix series, the MSG
instruction provides the application possibilities described in this chapter. For other PLC types,
please consult the programming documentation for the corresponding PLC.
Note!
When you use several MSG BLOCKs per adapter, you can work resource-friendly by
sequential triggering and hold available enough communication reserves in the
EtherNet/IP module for further possible clients.
Application note
An example of parameter data transfer (read/write parameters) in a "AC Drive Profile"
application can be found in the download area (Application Knowledge Base) at
