Tie the ControlLogix into pc and send to the IA system via OPC over
ethernet.
We used the RS Linx OPC server & the IA OPC client running in an AW70x.
Note: Invensys has just released an OPC server

Subject: RE: PLC Question
Glen,
I don't think there is a real good answer, but I've seen it done. I have
copied some old information I found below for reference (from Foxboro tech).
There are several options depending on the amount of data and type of
communications. From the Foxboro perspective, the easiest way would be to
communicate to the ControlLogix as a PLC-5. This would require a little bit
of configuration on the Rockwell side. I hope this is helpful.
Regards,
Jason

A-B ControlLogix PLC's
Many Foxboro customers are purchasing the new Allen Bradley ControLogix PLC
and asking how would we interface it to I/A Series. The ControLogix product
is designed around their new ControlNet data highway and uses an object
oriented data naming structure. Fortunately, Allen Bradley also supports
Ethernet and DH+ with PLC5 data table structure so that all of our
traditional interfaces can be used. When a data object (up to 40 characters
in length) is created, a pull-down menu is available to assign the data
object to a PLC5 data table. In addition, Allen Bradley will be introducing
a fault-tolerant ControLogix configuration with two processors and shared
I/O. As a result, we can interface via the following methods:
1. AB Integrator 30 to AB 1770-KF2 or 1779-KFL DH+ module in single or
redundant ControLogix configuration.
2. AW51 or AW70 with Ethernet interface, FoxBlocks and AB Interchange or
RSLinx software.
3. AW70 with DH+ interface, FoxBlocks and AB RSLinx software.
4. Micro I/A with AB Ethernet interface.
5. AW70 with FoxBlocks and DDE I/O Gate through a serial or Ethernet
interface which addresses data in the native ControLogic naming structure.
6. AW51 or AW70 through an Ethernet interface with a third party OPC
software which addresses data in the native ControLogic naming structure.

I for one would be interested in some more detailed information.
I have asked Foxboro about this for a couple of years now with
no results.
