A16 Modbus and Coil

[Arek]

I have a problem when controlling via modbus. When coil No.1 is activated, coil No.9 is activated on board. When starting coil No. 9, coil No.1 is activated on board. The coils work interchangeably. 1->9, 2->10, 3->11....8->16 and 9->1, 10->2, 11->3....16->8. The same situation occurs with input.

what's wrong?

you can download KCS firmware, test whether you can control every output correctly.
then enable RS485 modbus protocol. what's your command for turn ON output1?

In KCS firmware everything works fine. This problem occurs only after reading via Modbus. I use Open ModScan software.

you can test with modbus-pull tool.
