Tubular - Might not be enough but I'll check it out. I need 8 thermocouple inputs, some analog inputs, a few outputs to control hydraulics, and a way to control a few frequency drives.
I am going to be away from my computer so I won't be able to do much research today.

I found a local siemens dealer and gave them a call. The salesman called me back, and I tried to explain what we wanted to do. Upon hearing that I had not previously programmed siemens plc's, he was done with us small fry. Sorry, dMajo, I tried. If you were the salesman perhaps we could get somewhere with Siemens.
I helped a friend of mine at the sawmill today. He has a woodmizer. It uses a directlogic205 as sold by automation direct. They have had no problems with it.
I keep seriously considering the prop yet. If I follow what you are saying I could use the anybus to connect to the IO.
I don't have a clear concept of how the pid loops would be set with the directlogic software. They have a block of memory set aside for misc that the cpu accesses using some preprogrammed pid formula.
I am dragging up this thread for a few more questions. I have been doing more research here. After looking around I have come to the conclusion that I really would like PLC software that includes structured text.(After realizing what it is.) If Timothy or Dmajo reads this, or any one else with some info on this I would appreciate some comments.
What kind of price range can I expect to pay for software that is capable of doing such?
Try RabbitSemiconductor - they have a PLC kit with hardware that does Ladder Logic and Structured Text and all the other industrial programing languages.
Have a look at Hiquel (www.hiquel.com) PLC's.
I work for an industrial automation importer/distributor who sells HIquel in NZ and do some programming of these PLC's myself.
They are programmed entirely in power point (you just run a simple macro and it sets everything up) using drag and drop flow chart symbols so anyone who can read a flow chart can program one [noparse]:)[/noparse]
They are inexpensive (a basic PLC goes for ~$700NZD, <$350USD) and if you can find a basic touchscreen with serial interface, there are drag and drop serial objects you can use.
Hope this sort of 'plug' is allowed on the forums, if not feel free to remove it [noparse]:)[/noparse]
I need to use an HMI with ethernet capabilities. If I stay in the mainstream with the plc, I can use a variety of hmi's because the protocols are all set up for me. For example the C-more hmi is compatible with AB, siemens and others, but don't list abb and some of the smaller companies.
This thread probably belongs in the sandbox. My apologies.

I called automation direct today and talked to someone that was quite helpful. They have a terminator field io setup. They have different communication modules that connect to the IO. Ethernet, modbus/rtu, modbus/tcp/ip,profibus, and devicenet. Here is one module that we would be using - web5.automationdirect.com/adc/Shopping/Catalog/Field_I-z-O/Terminator_I-z-O_Analog_Modules/T1F-14THM

What AB stuff do you like working with Timothy?
Link:
http://www.rabbit.com/products/Embedded_PLC_App_Kit/
Price: $599.00
Caveat: I've haven't used it, my main experience was with Gould-Modicon PLC's.
FWIW
