Honeywell controlbus coms to AB plc

[joecontrol]

I am looking for any info on AB PLC integrated to honywell 7800 series flame saftey via controlbus comms. I am looking to use Flex I/O or a controllogix plc and it would be great to just talk to the flame relays.

I've only used Modbus RTU on the 7800, not Controlbus, but some Controlbus info is explained on the spec sheet for the model QS7850A General Purpose Interface ControlBus Module

http://customer.honeywell.com/techlit/pdf/PackedLit/65-0171.pdf

in part:
The protocol definition and device information is available to any company that wants to create a system to communicate
with the Q7700 Network Interface Unit or any device
connected to it. This information is contained on a single IBM format 1.44 Mbyte floppy disk, part number 206610A.
Except for a read me file, the contents of this disk are compressed in a zip file.

The disk contains:
- The protocol specification
- Device and point description files for the control devices, calls to a library of access routines (both the program and the access routines are included in C language source form)
- Instructions and a ROM image file to convert any QSxxx
card into a ?Testcard? device that implements all of the data
- A PC program to test and demonstrate the GPI Card and
its protocols. (An RS-232 to RS-485 adapter will be needed
to connect the PC RS-232 port to the GPI Card RS-485
port.)
- A PC program to demonstrate the GPI Card binary to
ASCII conversion of reply messages.
