Hey guys,

I am having issues to connect my Raspberry-pi 3 Model V2.1 with my PLC-S7 1215C DC/DC/DC.  
I'm running a Node-Red program on the Raspberry that worked perfectly when operated from my laptop.  
The connection between Node-Red and the PLC happened instantly and there were no Errors.

Now I have put the Node-Red program on my Raspberry, made the Ethernet connection with my PLC but I'm inable to accomplish connection between these 2 components for unknown reason.

The Ethernet ports are working, the cable is good  
I've disabled all kinds of Firewall

Any form of help will be taken with pleasure

Thanks in Advance

Jeroen E.
