Hi, Would like to know if it's possible to read/write value on GDS from the linux using C# or python app ?

    Yes, you can use the REST interface to read from and write to GDS variables. Those GDS variables in turn can be linked to Axioline I/O points, giving indirect access to Axioline I/O.

    Hope this helps.

    Thanks a lot I will take a look, but I was hopping if it's possible to use modbus instead of rest to expose those variable ?

    Yes, this is also possible. The Modbus/TCP library can be used to create a PLCnext Engineer project that maps GDS variables, including Axioline I/O if required, to/from Modbus registers in a Modbus/TCP server. When that PLCnext Engineer project is running on the PLC, then you can use a Modbus/TCP client, implemented in any language, to read from & write to those registers.
