Hi, According to the Modbus spec there technically is no Register 0 or coil 0 ... however many vendors don't implement their protocol-stack correcly according to this spec. If you read Coil 1, all addresses are sent over the wire as x-1 ... so 1 becomes 0 ... please try if simply adding 1 to all your addresses gives you the results you're looking for.
