Dear Haril,

I am trying to build connection between IOT 2000 and S7-1200 using Node-Red S7 communication documentation but unable to do so. I want to read and write the data. Can you guide through, how did you do it. First of all, I am confused with the physical connection between PLC, IOT 2000 and PC. Secondly, unable to get gauge reading as described in Node-Red S7 communication documentation.

Hi, I just recently started on IOT2020 and Node-Red. I have established simple connection of IOT2020 to S7-1200 using the Node-Red S7 communication documentation. I can do a simple READ and WRITE of data. But what I want to do is to send a list of data such that S7-1200 is able to read it, in either string or JSON. Is there a way to do it?

etc. I want to send information like QTY: 2, NAME: John, Register Number: 10... all this kind of data in a bunch. 

And will S7-1200 be able to split the information and receive it individually?

Best Regards,
HarilSHari
