Hi! What are the best practices for querying multiple Modbus devices? Single PRG or maybe multiple PRG (so basically multiple thread) per each Modbus device.
In my current implementation I'm using single PRG and I'm utilizing FbMbMasterMultiQuerySerial and WagoAppPlcModbus.FbDigitalTwinMbSlaveDevice in eCockpit with PFC200. I've the timer with 2 seconds delay there and it was working fine for single device. But now I have three Modbus devices and for two of them I need to run 2/3 queries to get data from all registers. I noticed that the delays for getting the data from the Modbus devices is much bigger right now.
