EtherNet/IP, 2 kinds of connections
Dear Sir/Madam,

I have never used netFIELD as an EtherNet/IP adapter, but I'd like to ask you the following configuration, please.

Is it possible to perform the following communication?
- netFIELD Connect, PLC1 and PLC2 are connected on the same network.
- Create a Node-RED container and perform I/O implicit communication between netFIELD Connect and PLC1.
- netFIELD Connect listens (wiretaps) to I/O implicit communication data from PLC1 to PLC2.

Because I want to exchange data between netFIELD and PLC1, and gather data from PLC1 to netFIELD at the same time.

Thank you very much for your advice.
Best regards,
Well Tad, I can give you just the same information as I have given in thread https://forum.hilscher.com/thread-733-post-3187.html yesterday already.

The netX51 industrial ethernet controller itself can support your requirements if configured well and a corresponding Linux application is running on the host. Hilscher is only providing C soure code for the standard use cases of a single implicit connection to a single PLC here https://github.com/HilscherAutomation/ne...g-examples which works on both the netPI RTE 3 and netFIELD Connect since there are both supporting the same netX51. There is no example how to program your requirement.

So you have to take the programming manual from here https://kb.hilscher.com/pages/viewpage.a...d=25863152 in the correct version and start programming your own C coded netX51 host program and then extend it for example by an MQTT client from here https://github.com/eclipse/paho.mqtt.c to publish your acquired netX51 data as topics with the MQTT client function to an MQTT broker container and then you have it immediately in a standard Node-RED container using an MQTT client Node-RED node and subscribe to your topics.
