I need help on writing a ladder program to recognize a first scan on power on to start a timer:
I am using VersaPro to write the ladder program and this is what i need to accomplish:
During the first 30 seconds after power-on, flash the light on for 1 second and off for 0.5 seconds repeatedly. After 30 seconds, have the light go steady on for 10 seconds and then go off. If switch is cycled on then off, the program should restart as if a first scan.
Please help me as I am so confuse on ladder logic programing...
I understand the problem but i dont understand how to translate it to ladder logic program.
Thanks in advance
