It is yes to all, but in my frustration last evening I tried som more variations, and now I have a sequense for the communication that functions. Not so saticfied with it, because I thougt I hade controll if each Modbus block was finished before next Modbus block was trigged. In the smal examples with Modbus RTU thei are using a manual trigg of an Modbus block, and the trigger bit is RSET on the end of the Modbus block.
