We've been getting this fault intermittently on a 1756-ENBT module. PLC needs to be powered down to reset it. The ENBT module revision is 4.8.
There is no PLC to PLC communication on the Ethernet but there are 3 SCADA systems reading/updating approx 200 tags each on the processor at 200ms update time. We have a system next to it that is running with no problems. The second system is identical except that the ENBT module is revision 4.3.
Any ideas.
