Hi I need help, I have installed the EDS for the 5069 Compact Logix controller into network configurator 
but I don't have options to link it by clicking and dragging one on top of the other to link tags between, 
if anyone has a guide or knows how to do it can you please post it thanks.

You cannot.  AB Logix family processors do not have support for adapter mode.  They must be the scanner in any exchange.  You will need to create tag sets in the CJ1W-EIP21 and manually give them connection point (assembly) numbers, then use the AB generic ethernet module.

The typical way to establish an implicit connection between a CJ and a Compact Logix is to have the CL PLC control the communications. You can use the Generic Ethernet Device profile in Studio and assign instance numbers to the CJ network variables using network configurator.

Just a bit of a gotcha when doing this - Make your input assembly on the CJ side 4 bytes larger than what you ask for with the CL PLC. This is to accommodate the run-idle header.

Example:

CJ input assembly size in Network Configurator: 104 bytes

Generic Ethernet Device assembly size in Studio: 100 bytes

This is only for the CJ input, not the CJ output.
