Therefore I already installed the recent Node-RED Release 1.2.6 and Node.js V8.16.0 (can't update, why). Version of node-red-contrib-s7 is also the newest one (3.0.0) Now to the connected Hardware: My Iot2000 Gateway ist connected to my Computer via X1P1 Port, static IP: 192.168.200.1 Port X2 is connected to my router (dchp). -> until here everything works fine. I'm able to start putty and node-red in my browser. But when I try to connect to my PLC (only connect to my computer via IP 192.168.200.3 at Port X2), nodered throws an error: "Error: connect EHOSTUNREACH 192.168.200.3:102". My question is: Did I forget something in connection settings or am I using incorrect IP-addresses or what is the problem here? PS: I also tried to install nodered on my PC and it worked fine. So I don't know where the problem is, but I guess it es something with the connection... An yes, I found some documents about my connection, but nowhere it is exactly described how to connect the hardware within IPs. Thanks a lot. Best regards

Usually there is no NodeJS8 support by our processor. And you cannot work with node-red-contrib-s7 version 3.x.x, it only supports NodeJS 10. Here is a reference how to install an older version. The version 3 of the node will crash once it is connected to the PLC, but you are not that far... I don't get your network completely. What IP addresses does your PC have? And is one interface of the PC connected to the IOT and another interface of your PC connected to your PLC? You need to connect your PLC to the X1 interface of the IOT as well, otherwise it is not possible to get a connection from IOT to PLC. If you want the IOT to communicate with the PC and the PLC via X1 (192.168.200.1) you need a switch. EDIT: It would be helpful if you could create a small drawing how your network currently looks Best regards!
