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,

Thank you very much for your examples! Gives me the progress I required :)

By any chance, is there also a way to store strings in an orderly manner such that I will be able to give the output depending on a input from the S7-1200? Like for example, a string is sent every single time there is an input from the sensor. Could this list/order be kept at the S7-1200 or the Node-Red side? 

Thank you very much for your help.

Best Regards,
