Before, I created a premision set in the FactoryTalk Administrations Console. I use Studio 5000 V31.00.00. Please, give me any advices. ------------------------------ ...

RE: Redundant ControlLogix without IP swapping

Thanks, it was very useful information for me. The EN2T module is connected to a ModbusTCP gateway​, converts Modbus to EtherNet/IP. I think ,in my case, the solution is to use the ModbusTCP server sample code. As I understand, it uses CIP Class 3 connections (correct me if I'm wrong).

Hi @fuzzy logic!​​ Thanks for reply! Sorry, I didn't write in my post: i changed IP address only for EN2T module in slot 2, it didn't work. And as you mentioned earlier my EN2T module is not used for I/O or Produced/Consumed connections. In RMCT, on primary chassis, there was error message for EN2T ...

​Hi all! I have a redundant controllogix 1756-L71 (Rev 31.052) with an EN2T card in slot 2 for Ethernet / IP, EN2TR in slot 3 for remote I / O. My redundant system uses IP swapping, but I need to use it without IP swapping. To do this, I changed the IP address in the secondary rack (changed from AAA.BBB.CCC.DDD ...

Thanks for reply! If I understand correctly, you suggest that, I have to connect the EN2TR cards, I/O AENTR and DLR switches (instead switch#1 and 2) in one ring. But in this case, problem still remains, because FTE connections (left and right side in my topology) will be interconnected in this ...

Yes, you are right, It is MOXA-5105. I described the topology as below. The problem is in Link#1. Our DCS system uses FTE and it doesn't work in the ring ##HL38

Summary: Redundancy system in FTE network We need integrate CLX redundancy rack in FTE network for ModbusTCP data exchange with DCS. Each rack has EN2T card and connects to MOXA 5150 gateways, which converts Ethernet/IP to ModbusTCP. The problem is follow: for normal operation, a connection between ...
