A Message instruction can be used to check the Ethernet link status of a 1756-ENBT or other ControlLogix family Ethernet module port to determine if there is a good Ethernet link.

This example shows how to send a CIP Generic Message to Class 0xF6 Instance 1 Attribute 2.

The applicable page from the EtherNet/IP Specification (www.odva.org) is included in the ZIP file. The program file was greated with RSLogix 5000 v15.
