Hi Folks, I haven't programmed a PLC since back when the SLC503's first came out and I have forgotten a LOT! We used APS software back then. Here is my present problem.I need to program a Micrologix 1500 with the RSLogix 500 software.It is being used ONLY to monitor a sewage lift pump station and communicate by modem back to a county SCADA system (report by exception). There are about a dozen discrete inputs and one analog input for level.What I would like to ask are there some "housekeeping lines of programming" that I should include in the beginning of the program? Things that should be initally set like in case of power outage or reinitalizing data registers (for instance setting them to zero).I hope the question is clear. thanks a lot for your help. BTW Phil's book was a great review. I wish he would write a sequel dealing with analog and communication.Thanks, Bruce
