I Have 2 Compact Logix L35E's communicating over ethernet. The only reason the two communicate are for Truck and Railcar Loading Messaging for pumps. But on the one controller I have 4 Cooling tower Fans that are on the PLC, and every time the communication goes it knocks all the cooling fans down. I've basically thrown everything I can think of at. I've Changed the controller, I've changed the power Supply, Checked the Patch Cable for the PLC to the Network Switch. Had our IT department check all the network switch ports for anything unusual and there is nothing. I'm monitoring the communication with a Get System Value so I know that its a communication issue causing it. Anybody have any oddballs to throw at it?
