Bailey dcs upgrade
(OP)
We have a bailey system running close to 7000 tags on site. We intend to replace it as it has close to 12 years worth of support.Anyone out there has gone through the same process?? I have two ideas in mind:
1. Change to clgx plc
2. Install an ABB interface to the current system.....preferably an 800xA system
3. DeltaV system
Any ideas out there??

RE: Bailey dcs upgrade
On a 7000 point system, I recommend going for quotes and investigating each of their offerings. Limit the DCS/PLC vendors to 3, possibly 4, to make your review easier for you.
Costs on a 7000 point system can differ up to 40%, so it's worth taking a look at multiple vendors. You also need to have intimate conversations with each vendor to understand their systems offerings and capabilities. A 10-20% cheaper vendor may not have all of the tools that fit your plant and personnel. For a 20year investment, this 10-20% up front savings may cost you more in the long run.
Using US$1000 per I/O point when designing a new system.... Add the vendors costs and your internall engineering, and it will come out to be about $1000/point. So, for 7000 points, it'll be US$6-8MM.
A 20-40% difference in cost between vendors is money you can't afford to give up without a comparative bid!

Add Foxboro's I-A system, Emerson's Ovation, Honeywell's product (name escapes me - sorry) and perhaps Siemens PCS to your list of possibles.

If we learn from our mistakes I'm getting a great education!

PLCs are not out of the question and many have good offerings. In North America, it seems Rockwell (Allen-Bradley) has captured a large portion of the market. Don't know the players in S. Africa.

First off I will state that I do work for ABB in the US. I hope you or other users will not take this as a sales pitch. I'd hate for you or any other user to replace your system for the wrong reasons. Support timeframe is no longer an issue for your Bailey system. Have you heard that ABB as of November 2010 announced that the Bailey system will be supported indefinitely? Additionally in April, ABB announced new products and development activities at all levels for the Bailey system under the name Symphony Plus. There is a path forward for all levels of your system. Hope this has not offended. Good luck with whatever you choose to do!
