      Hello everybody,

      I have configured Modbus IP type data source with "Use multiple write commands only" check active, I can use the function FC15 Write Multiple Coils and FC16 Write Multiple Register, but I cannot write several outputs/ registers at the same time in the same request. According to the Modbus protocol it should be possible to do it.

      I use a meta data and change at the same time the outputs/registers but then the communication driver separates FC15 / FC16 in several requests.

      Is there a way using these types of functions in which several outputs or registers are written in a single Modbus request in mango? I am doing something wrong?

      Thanks in advance!
