A simple control system that will switch on and off some valves (10) and report some data all from a Touch screen LCD display.
System will not have to think just convert analog into pressure etc.
Valves will be manual from the screen not as part of algorythms.
The System will have the following i/o:
44 Digital Inputs
22 Digital Outputs
15 Analog Inputs
1 LCD(TFT) display with touch screen for User interface. ( Hazardous area Classification for Europe Zone 1)
All digital inputs are feedback from (Open & Close) of the solenoids connect to the digital ouputs.

Analogs report some pressure etc.
The question is it cost effective and justified to put this onto a PLC with a seperate PC running an HMI or just add i/o card to the PC.
Second question if it is done by the Cards in the PC method can it still be connectedc to a SCADA package like IFIX or WonderWare.
