Enter Message Logic To send or receive data from an EtherNet/IP communication module via a
message, you must program a MSG instruction in the local controller’s logic. If
the target module is configured in the I/O Configuration folder of the controller,
browse to select the module or manually type the message path in the MSG
instruction.
Add the EtherNet/IP Communication Module to the Local Controller’s
I/O Configuration
To use the Browse button to select the target device of a MSG instruction, add
that remote device to the I/O Configuration folder of the local controller.
Within the I/O Configuration folder, organize the local and remote devices into
a hierarchy of tree/branch, parent/child.
