(OP)
I have been blessed with my newest project to design a system. There are several controls in my new process all having rs-232 connections approximately 9 of them.Mainly temperature flow and pressure. I am looking for a low cost, reliable, easily operational SCADA system (I am guessing) for data aquisition and control. Any help on where to start would be appreciated. Books, websites, or your experiance etc
Thanks
Thanks

i would recommend contacting the manufactures of the controls you are thinking of using. you will probally find they also offer a system which you could put together yourself (with tech support)
it worked for me, my first scada, using plc's i kept them all the same and also used the same manufacturer for a system to set up my self. using tech support and manuals i got there
good luck

RE: beginner SCADA
free labor would always be welcome but the main point i am making is that some companies do offer great tech support to get you started and up and running(what better way is there to sell a product)
with the support and some homework you can set up a simple system which sounds like thryll is aimimg for

Plenty of case study and u can download the 20 days trial version for free. Also got fake I/O server where u can actually simulate the whole process without even connection to the machines. Other SCADA software would be Wonderware.
Good Luck

I have ever needed plus it's fast, highly connectable, very scalable, good entry cost, and my first job with it took 5 hours from installation to deployment which is hard to match with the others I've dealt with. You can get a LITE style version at www.automationdirect.com under software products.

Hope this helps a little.

Chemical engineers are the highest paid in the profession. If you would like to do electrical as a hobbie that would be ok.
Anyway just contact your local scada dealer he will design the system for you but beware it may come out bad or will not work.
The electrical business is just like the chemical business. You need mentoring.

EIA/TIA-232 interfaces require some protocol. Modicon published Modbus in about 1980 as an open protocol. Most PLC and DCS suppliers have EIA 232 interfaces but there are some catches in the interface. IMHO, EIA 232 interfaces are becoming obsolete as Ethernet is much easier. Among the EIA 232 interfaces programming for the bits can run from 0-15, 1-16, 16-1, 15-0, etc. You will spend some money on the interface and some time implementing the first interface. Each interface may be different unless the equipment is very similar.
Your SCADA application may be much easier using 4-20 mA than EIA 232 unless there is a lot of data to be collected in each interface. Also, Fieldbus could make 4-20 mA obsolete over this decade.
Good luck.

RE: beginner SCADA
I was going to ask if anyone new of any web site that would give me some info on field bus applications
but with the responce that thryll got from xnuke I don,t think Ill bother.
what is this the closed shop union ?

I'm a well experencied plc-programmer but I know really nothing about all that ethernet-stuff. I guess I will have something to learn (and try out) the next years.
So, thryll, you're not alone...

what exactly IS/ARE the type of controller(s) you have to connect to ?
If you provide this info, you will get much better advice !
What MAKE(s) ?
What TYPE(s) ?
