  1. Hi,

    There's no yet support for a nested STRUCT over JSON, if the structure is not too complex, you can try maybe (never tried) to build an ASCII buffer having the entire JSON and publish as a RAW type.

    Need to try that.

    Message composer feature might make your life easier, building the structure once and setting the values of the tags to get the buffer that will have the exact JSON structure..

  2. Hi Fernando,

    Please explain your task clearly, I will try to provide you with the right answers.

    I believe that that is to add the slaves to the protocol, and it means that you can't select a device which IP has not been added to the configuration FB first?

    I can communicate without problems, but using the same socket for many devices requires closing the connection and connecting to the other IP before sending/receiving.

     

  3. Hi Hoops,

    Before STO arrived to the market as embedded drive safety functionality, engineers implemented safety using safety contactor at the way I described previously.

    As I wrote, in order to avoid any damage, if your motor stopped and MC_Power is off, no current towards the motor and the contactor can cut safely the motor power loop.

    Also, even cutting during operation is fine and the motor will freely run until stopped, and that's fine for emergency.

    If you really need Safe Speed 1 or Safe Speed 2 safety functionality, you should use drives that provide that safety functionality.
