Hi Everyone,
I am currently trying to communicate ControlLogix PLCs via EtherNet/IP with Delta V DCS. There is a VIM2 card configured for EtherNet/IP devices.
As per Mynah's knowledge base, VIM2 supports Class 1 (I/O) connection with ControlLogix PLCs as well. The VIM communicates with ControlLogix devices using the generic 1756-ENBT format. Each ENBT corresponds to a VIM dataset. This functionality is available in simplex VIM architecture only.
I was able to get success along the way.
I have configured 3 PLCs with DCS. They were never connected to the DCS at the same time together as the plant was shut down for maintenance. Now on startup, once all 3 PLCs came online I started getting communication errors with DCS.
During troubleshooting, I observed that when either one of the 3 configured ControlLogix PLCs is connected with the DCS, it works seamlessly. and just when any other PLC is connected alongside, both of them lose communication. Further troubleshooting is being carried out. The communication gets back up only when I have removed all but one and unplug/replug the cable.
PS: I double-checked the network for duplicate IP addresses but didn't find one.
Am I missing something? I do not have much experience with the Delta V DCS.
Thanks,
