Extension xS40 don't work

  • Hi,

    I have Neuron M303 and xS40 and anything on xS40 don't work. I have directly connected DI from M303 to DO from xS40, but it is always off. (DO from M303 work fine)

    I have the modules connected via Modbus RS485.

    I tried set DO on xS40 in Mervis to true, but it still off.

    Can I read online the status of DI or DO in Mervis? Or with some tool? Or if the Modbus work?

    Thank You
