Support Questions / Mitsubishi FX5 via ModbusTCPCOM
« on: February 09, 2018, 10:50:02 AM »
Hey guys,
got some problems using a Mitsubishi FX5 with ModbusTCP.
For my test I'm using just 1 AnalogDisplayValue.
In general it is working. I checked Standard-register from documentation D0 (MODBUS-address 40001). No problem.
But for my project I need to use extension registers R.
In the documenttation I found address mapping R0 - R32767 (MODBUS address 2140h - A13Fh)
So in my opinion correct address for R0 should be: 40000 + 8512 + 1
But with this address I always get MODBUS error 03: Illegal data value
I'm not sure what the problem is. Can anyone help me?
