I got a problem with modbus rtu over tcp protocal to read some energy device.
A 485 to tcp servert port was used. I had tried with modbus poll to read those addresses，everything goes well.
However with ignition modbus rtu over tcp module, the bellowing warnning was continuously loged.
ReadHoldingRegistersRequest 19Jun2020 21:19:40 Request failed. FailureType==TIMEOUT TimeoutDaemon 19Jun2020 21:19:40 ScheduledRequest[com.inductiveautomation.xopc.drivers.modbus2.requests.ReadHoldingRegistersRequest@2085e362] request with key “937” failed due to timeout.
I add those nodes 1 by 1 for test, when the number for nodes is 1 or 2, everything is ok, but when the number bigger than 3, the warnning occurs.
It seems something was wrong with that modbus rtu over tcp module.
Does anyone else meet the same probelm ?
