I am very, very new to PLCs. I only have experience with Picos, but I knew enough to save this from the dumpster. Apparently, everything on it is functional. It has 4 processors, 7 DHRIO, and 4 redundancy modules. Can anybody give me a rough ball park of what a reasonable asking price for this thing would be? I have had a couple of people express interest in it, but I lack the knowledge to determine what it is worth.
