For anyone who is following all this, I have been doing a cost comparison for the system I initially described in post #1 (12 Digital Inputs, 12 Relay Outputs, 2 Analog Inputs (1 @ 0-10VDC & 1 @ 4-20mA), 1 Analog Output (0-10VDC) and 2 quad. encoder inputs). Using the info I have received from the responses here, this is what I have come up with so far:
I am seriously considering 3 possible solutions:
1) A DL06 main PLC with a DL05 remote and Koyo's 6" Color Touchscreen
2) A DL06 main PLC with a DL05 remote and Maple Systems' 6" STN Touchscreen.
3) The Unitronics V280 with the Snap-In I/O module (includes Touchscreen and PLC)
While I have level the playing field as much as possible, I am aware that I am not making a truly direct comparision between the touchscreens in 2) and 3). However, each of the two touchscreens offer a feature that the other doesn't; the Koyo offers 256 colors but does not offer pop-up screens and the Maple is offers only four shades of blue but does have pop-ups. These seem like reasonable offsets to me.
I will have to purchase programming software and required cables for any system I purchase so this is included in my consideration. I have included these costs separately.

3) Unitronics - Total Comparative Price = ?
I have only just requested a quote from them so I have no numbers to share yet.
Just thought you might like to see the breakout so far.
