Hi All,

We have a 4X Rx3i PLCs that use Ethernet Global Data (EGD) to talk to each other.

At the moment we a facing EDG communication fault being generated and it trips the entire pumps

What the likely causes of EDG faults:

We have replaced PLC Ethernet Interface Modules-no fix
We have tested the fiber optic cable-the readings show its OK

Also,can someone explain what PLC heartbeat is?
