i started like you on the AB stuff..but back then we were using top of the line SLC100's !!! Fancy stuff!! I then lost touch of the PLC world for a while. About 6 years later i went for a showing of a plant. (I am a contractor and we were trying to get in the door..). I talked to them about my...

Scotty if you have a laptop around that you can dump and install windows 3.1 or win 95 then just go for the modsoft program. It will work from the serial port in those versions withoput much agro...I assume you will not be using modbus plus if it is a stand alone unit..If you are then you need...
