Schneider PLC Counter plus Timer

[JPalas]

Hi there

So I’ve been trying to complete a program to a Schneider PLC in Ladder but having some a serious problem that can't seem to solve.
I’m trying to add a timer, this needs to add a block of time every time a contact is activated (coin validator). Tried so use a counter and a pulse timer, but doesn’t add time to it.
Could someone give me any idea?

Thank you so much

Hi @JPalas ,

I am not 100% sure what you are doing but if you want to count time you could use the system bit %S6 + Rise trigger to count the time in seconds of an event that is happening (in my example how many seconds a motor is activated) you will need to add a operation block that adds 1 to a %MW or %MD variable:

If you want to count minutes then an additional comparison must be done to reset the second and add 1 to a variable that stores the minutes.

Let us know if you need any further information.

Hi

Thank you for the answer.

I can see now that my post wasn't clear.

I am programing a m221 for a self service car wash, everytime someone inserts a coin in a coin validator (contact) I need it to add a block of time to a timer to prolong the user service time. 

I can easily add the timer but need to add time (66seg blocks).

Thank you
