one month later I have finally recieved a quote on programming software Edops2. The cost is a little on the high side 480 pounds stirling, that translates into $1166 Canadian for me, ouch! also required is a communications card "o43" that plugs into the plc rack at a cost of 351 pounds stirling, $853 Canadian ouch again! Manuals for the processors are $115 Canadian each. This looks like a very expensive aproach to looking at the program. I don't know what other option I have.
