I'm not sure if this the right place to post this. I work for a company that runs rslogix 5000 for a few plc's. I dont know anything about plc's nor do i know rslogix. I do get into the program to make some changes at times but just minor. I have an issue now when i start up the program and open the ACD file the window is blank, no ladder logic. If i log out as operator and log in as an engineer then it shows up. In the past it has always shown up when logged in as an operator. Any ideas what is wrong? problem we are having is that all tech support has left, so kind of in a bind.
