Hi guys,

i'm in search for most basic example for reading and writing json file in plc 1511. Here is the code example, and what i must do is reading specific strings from file and saveing to the PLC, for example: PAA00000, 900000101.SNTTEST... and so on. After that, making my own json file with identical structure. The file I need to read and write is on a PC that is connected to the PLC via ethernet.

Perhaps you can find suitable blocks to accomplish your task here:

There may be other open source libraries available (like Siemens' library site: https://support.industry.siemens.com/cs/document/109738702
