Are you not able to understand how the timer works???
Drawing ecample is there in the site itslef https://www.plcs.net/chapters/time16.htm
check out the second figure they have shown an example
Where 0001 is an input contact (it can be any digital input or any contact of other relay which enrgizes the timer T000 (same as u energize the relay)
In second rung there is T000 contact becomes close after the delay of 100 units (can be seconds) from the time the timer was energized which in turns energizes output O500
Hence you get On delay time
See this animation https://www.plcs.net/chapters/timeran.htm
note that plcs come with variety of system bits. some of them are clocks
that can be used just like you did in a original post. those clock bits have
fixed timing (like 0.1sec, 0.2sec, 0.5sec, 1 sec, etc.). to make custom clock you will need timers. now what is the duty cycle of the clock you want? 50%?
you could try somethign like this using single timer:
Code above will work on any plc, attached examples are for AB and Mitsubishi. note that AB example generates 0.5Hz clock.
you can change this by entering different value in preset. you can change base as well. i rarely have need for 1 sec. base so i decided to use it in this example
Hi, i am also looking to turn on a light bulb once i activate an enable input the buld will light for 2 secs then go off for 2 secs then turn back on and repeat the cycle as long as the enable input is active. any ideas?

It might be wise to start a fresh thread. This thread dealt with a PLC (Programmable Logic Controller) using ladder logic in the drawings. Do you have the same? What voltage and current is your lamp? How you do what you want to do is a function of what you have.
