I have been using an S7-300 station and have come across a Scorbot-ER III. I have been trying to find out how to wire things to the connectors for the stations external interface sockets. The search has been going on for days, and I haven't found anything closely related. Can anyone help me with finding the guide? If it is on a web site, please post it, or if it is in one of the books that came with it, let me know which one.
