Modicon TSX Microscan to AB Micrologix communication

Hi,

We are trying to interface Allen Bradley Micrologix1100 with Modicon TSX Microscan through Modbus.

Micrologix is Master and Modicon is configured as slave PLC.

This connection is to Modicon's D+ And D- terminals.

All communication parameters are matched with both the PLCs.
But communication is not getting established.

We see blinking of the LED on Modicon communication card but no dat is received from Modicon.

Can anybody help to resovle the issue?

Try to troubleshoot with something like Modscan software.

I don't know how it's done in this Modicon but I seen in another Modicons following: if Modbus request tries to access not allocated %M or %MW communication fails. Check your 0x, 1x etc. allocation.
