Compactlogix to Modicon Comms using Red Lion DSPLE

[ballack]

Hey guys,
I am trying to make an Allen Bradley Compactlogix and a Modicon Quantum talk to each other using a Red Lion Data Station.

So far I've set a communication protocol for the AB processor using the L5K driver and it works fine, I can read data from that PLC.

For the Modicon PLC I set a Modbus TCP/IP Master driver but I haven't been able to read any data from it, let alone pass data to another PLC.

I don't know if you require some kind of special setup for the Modbus driver?
I created a tag with the " IsDeviceOnline(x) " trick and it doesn't get anything from that PLC.

Help please?

Can you ping the plc?
Is the Quantum on the same subnet as the redlion?

Yes, I can ping it, it is in the same subnet and everything, but I don't know if there is anything special to configure.
