I am new to programming in ladder logic and am trying to write a simple program wherein outputs Y65 and Y66 follow the sequence:
- Y65 turns on for 30 seconds.
- Y65 turns off.
- Y66 turns on for 30 seconds.
- Y66 turns off.
I am using timers and internal bits to achieve this but I am having a few issues: 1) Y65 remains on for the entire time and Y66 turns on and off immediately. I have attached snapshots of my program. X1 and X2 are physical hardwired inputs; C1, C2, C3 and C4 are internal bits; Y65 and Y66 are outputs. Any help would be appreciated.
