Regarding DCS bidding
Thread Content
Dear teachers: What should be taken into consideration when bidding for DCS systems? Thank you
There are so many things to consider when bidding for DCS systems: controllers, IO cards, communication cards, networks, servers, operator stations, safety barriers, relays, power supplies, switches, and so on.
The last edit to this post was made by Hardmen on 2010-9-25 at 11:29. The most important thing when bidding for a DCS system is to find one that suits your project； There are many manufacturers of DCS systems, but each has its own areas of expertise; some have extensive experience in the chemical industry ； Some power plants have a great deal of experience ； There are sizes that vary ； The prices also vary greatly ； International brands are widely used and have mature technology, but they are expensive ； Insufficient service support ； Domestic manufacturers started late, but they suit the national conditions and offer excellent service ； So, consider your own needs ；
Find a few suitable ones for technical exchanges, and then make a decision

Okay, hehe, I’m quite interested in your new system that has achieved SIL3 certification. Could you send me some materials?
Let me put it this way: In my opinion, imported products certainly have better performance than domestic ones, but they are more expensive. Domestic products may have certain shortcomings in some aspects, yet they offer better service. If the control requirements can be met, it’s better to choose domestic products – is that a way of supporting local industries?
I’m sorry, we are still applying for it and the process isn’t complete yet. This system is XDC800, and it is currently in widespread use. The data is too large; you can download the relevant samples from our website. Thank you for your support. If that still doesn’t work, please send me an email and I’ll think of another solution.
There are technical specifications and commercial terms, which represent a comprehensive consideration; you should specify the performance indicators that are of concern to you, taking into account the strength of your maintenance capabilities.
