Dear colleagues, could you help please.

I have Prosoft Modbus module MVI69-MCM for CompactLogix PLC. With this module I need to communicate with modbus slave device (Modbus ASCII, 57600 baud, 8 bit, 1 stop bit, non-parity).

Address register of parameter that I need read from device is 30202.
Command configuration in ProSoft Configuration Builder is in snapshot #1.

But in logix all inputs values are 0. Except MCM.DATA.ReadData[100] = 2, that describes error. When I physically disconnect device MCM.DATA.ReadData[100] = -11
Port statisitcs are in snapshot 2.
What I'm doing wrong?
Thanks
