Modbus TCP/IP communication with controllogix redundancy

2 posts in this topic

I'm using Controllogix L61 redundancy system as a slave with DCS using ethernet tcp/ip socket programming. The communication between master and slave will fail after a switchover. Kindly give solution for this.

Thanks and regards,

Rasu

I very strongly recommend against this approach.   Rockwell does not support the socket programming interface on redundant controllers and any Rockwell integrator, support office, or engineering team should recommend against this approach.    This cannot be made easy, or reliable, or cost-effective.

Get a gateway device that is treated like an I/O device (like the Real Time Automation 460ESMC).
