[Counter with timer function]

Hi,

 

I'm looking for some help with the following:

My client is looking for a alarm in a existing program in U90 ladder.

He wants to have a alarm when a curtain input has been active for example 5 times within a curtain time for example 24 hours.

So I need a combination with a timer and counter to set a output alarm. For the amount of times I want to use a Variable to let the operator change it.

Can somebody advise me how to solve this or has a example for this.

Thanks Wim Zwart

Hi, I'm a first time user of the U90 also, I need to use a puls pause also, also with the reverse mode in it. only diferent is that i need a puls pause on one direction untill I reach a end switch, after that I need to activate the other running direction on the motor untill second end switch and than go to first step again. Can some body advise me on this please.

Thanks again for the help.

I'm thinking that great minds think alike. Yesterday afternoon I thought of the same process that you suggested on the integer management. Then to control the outputs based on the integer value.

I took a few additional nets to complete my "Timer Loop" than you but in the end we both use the same concept.

Now that I am able to run these timer functions I think the rest of my first Unitronics OPLC project will fall right into place.

Thanks again for the help I greatly appreciate it

Hi Michael, Can you help me out I'm a first time user also and I need to make a ladder with timer functions also, your timer functions are working well I only need to work with end switches as well. This means I will have a puls and pauze on motor right untill I reach the end swich for motor right. After that I need to activate motor left on a puls pause untill this reach end switch for motor left. Can you advise me on this please. Wim
