Read/Write JSON Objects in PLC

[Luschuerz]

Hi,

I would like to send or read a JSON Object from the Datalayer using PLC. Is this possible to do? 

Is there a Documentation on how to execute Methods on the Datalayer? E.g. Jog Axis not through the Motion callable but through the Datalayer motion/axs/Axis_1/cmd/...

Thank you
