Hello, I am new to PLC's, and am currently taking a PLC cource as a part of my degree. The course is taught using Logixpro. I am building a scale model of a trafficlight at home using a LG PLC (gm7U). I have it built and have programmed timers to cycle the lights. Didnt see sequencers as an option on GMWIN. I have added a set of timers to handle the crosswalk premption. It comes back into the normal light clcle at whereever the cylce is ( the crosswalk doesnt stop the normal cycle, just locks out one light so the walk timer run it), then gives it back to the normal cycle. The problem is it may revert back with 1/2 sec of green time left, then yellow...ect... which looks kind of strange. the documentation i found for GMWIN is not great. any sugestions or guidance would be appreciated.
Thanks.
Thanks.
