Hello everyone, I need your help to know how to set a path or routing with node-red-contrib-cip-ethernet-ip-enhanced for communicated with Controllogix PLC. I have a PLC destiny in a controlnet lan and a PLC bright by ethernet/ip but I dont know how set the path and I dont know where, because I dont see any file to write it.

Do you mean that you do not know where to configure the IP address of the PLC in the node? I haven't used that node but it is described in the [readme](https://flows.nodered.org/node/@sumit_shinde_84/node-red-contrib-cip-ethernet-ip-enhanced).

No, I have several PLC comunicated by controlnet and I need to read some tags from one of them. Only one PLC have a ethernet conection and already read tags from it, but I want to read tags from other one. In Studio 5000 the path is the next one: ETH\_ELECT\192.6.10.66\Backplane\14\A\10\Backplane\0

Where:  
ETH\_ELECT is the ethernet adapter's name in RSLinx.  
192.6.10.66 is the PLC IP (bridge).  
14 is the slot position of controlnet card in the backplane of the PLC bridge.  
10 is the slot position of the controlnet card in the backplane of the PLC Remote.

OK, I don't know how to do that, but possibly it is to do with

- **Connection Mode** : Choose the appropriate mode for your PLC:
  - **Standard (Unconnected)** - Default mode, works with all PLCs
  - **Connected Messaging (No Routing)** - For PLCs that connect directly without backplane routing
  - **Connected Messaging (With Routing)** - For chassis-based PLCs that need routing but benefit from connected sessions

You probably need someone who knows more about these systems than I do.

Yes, it should be in this option. In other programs like IBA PDA or Ignition is similar, but there a file where you can write the path, but with this node of node-red I can't.

Thank you.

You might be best to ask on the node's github page.
