All programming of a PLC, obeys a logic of operation of the control system. A timer can do a function in one system and can do a totally different one in another.
You must learn how each of the commands works, so you can read a ladder and build yours, knowing the logic.
There are techniques to make the scanning and execution of the program faster.
