I have been using PLC's very many years, I understand what they can do, but new to programming PLC's. I am working on programming an OMRON ZEN PLC for a very simple operation press start button run output 0 for 15 seconds then output 1 for 30 seconds and alternating until the stop button is pressed I have attached my attempt but I have something wrong, I would appreciate help in getting it right. I think once I see it correct I will have a better grasp of how to do this. Thanks
