All roads lead to Rome. Looking around for some time to get tips or find a better setup for WagoAppPlcModbus_MasterSerial than what I’m using.

For the SerialMaster there is an Solution called Multiquery. You can find it the Lib WagoAppPlcModbus → Advanced Modbus Master → fbMbMasterMultiquery. In the Applicationnote a2022006 you can find the description for this functionblocks.

the result of using multiquery might looks like this:

no problem, you can find the project here:
