Hi

I'm trying to get some values from a SINUMERIK 840D sl using the node-red-contrib-s7 on the IOT2040. Does anybody already done this successfully?
The part referring to Node-red, I imagine I will not have problems, but I have doubts about how to establish a profinet connection between these devices.

node-red-contrib-s7 uses the s7 protocol

From a web search:

The S7 protocol is designed for transfering data into SCADA systems via Ethernet. The PROFINET protocol is used for communication between PLCs and IO modules . The S7 protocol can be used for communication via PROFINET connector in the PLC device or in add-on communication modules

Thanks for trying to help me, but I know it's possible to establish communication, I just don't know how to do it.
