S7 Node on IBM Cloud


Im working on IBM cloud, doing my first app in nodered there and i couldnt find solution to some issue.
I have a S7 Siemens PLC, so i need to read some parameters from S7.

When i run my code via local, in my laptop, s7 node gets online, and the code run but with the same code in IBM app, it get offline. i guess is something about my ip i start in 192.168.x.x

I cant do this on IBM nodered app? the node is not configurated to do this? or just is imposible to conect the plc directly to internet then to app in IBM?

Thanks :slight_smile:

Hi @EstebanGV

A 192.168.x.x ip address suggests your PLC is running on your local network. A Node-RED instance running in the IBM Cloud (or any cloud) cannot see into your local network - it has no way of reaching your device.

The only way to do it would be to make your PLC accessible to the public internet and that then opens you up to all sorts of security concerns as to who is able to access it and how.
