UniLogic Modbus TCP error


Recommended Posts


the modbus communication gives -> error 3 = illegal data value.....

I see you want data of adress 1....

Sometimes the adresses of the modbus registers starts at 0, instead of 1... This is depending of the manufacturer of your modbus device.....

I should try using adress 0 and see what happens....

Maybe the length of the received bytes isn't what you expect ?
