I tried communication of Triconex with RTK P725 annunciator.
However as per manual the address for RTK is 2016, i sent the comm cards back to RTK to change the starting address from 40500 which is the DINT R/W range for triconex MBWRITE blocks. however when i connect the PLC with 725 it is giving error of invalid response from slave. Its not giving time out which means the wiring is correct.
Can some bdy help please.

Try check what you get as response. You can use the Modbus Tester from www.modbus.pl to see the data send/receive over modbus.
