Bailey Infi 90 DCS - Rockwell gateway ?

has anyone known of a gateway to bridge between a Bailey Infi 90 DCS and a Rockwell Control Logix 1756-L83 CPU successfully?

i believe there is a product called a GPI (General Purpose interface) or HGS (Harmony Gateway Solution) to bridge the 2 devices via some kind of point table in the device?

My Bailey Infi 90 DCS has the following if it helps

- 2 Only BRC300 CPU's in redundant pair mode
- 3 Only CIU01's ( Infi-net to Serial for EWS and Scada servers)
- NPM's etc

i want to set up a bridge to communicate between and existing DCS and 3 or more New Rockwell 1756CPU's.
i am located in Australia and hoping someone in USA has known if this has been done successfully.

any info on protocols etc is handy.

Oh forgot to Mention ABB are now the Vendor of Bailey DCS and are still supporting it.

Anyone know?
I have a quote for the device its $35,000
I am hesitant to place order without research

I did a bunch of research into similar stuff before, so take it with a huge grain of salt.

As far as I know, there's no direct bridge you can get, the best you can do and this is probably what they are selling you is a modbus bridge to Infin 90 then modbus over to Ethernet/IP.

I also know people have used Rovisys OPC to 90 then Kepware OPC to AB then bridge the two.

Many thanks Harryting

Yes your correct it specifies modbus tcp
