Hi,

1.Modbus send command should be adapt between slave and master. If one of side does not accept FC3 command but another side insist this query in this case we can observe packet error.
2. If you do not use some variables on slave side, when master packet is bigger than this side, you can observe this error. You have to control variables map of slave side. I recommend slave should be bigger than master query.
