Sysmac TON Reset

[MrT]

Hi All, 

 

Please can you assist.

I am trying to create a "delay" to slow down the rate that an action takes place.

I place a TON function black, but once run once it does not reset.

I need to know what function I need to put in the following rung or at the end of the rung to reset the TON function again.

Basically want to check a condition every 5 seconds.

 

Any ideas?

 

Many thanks

The TON resets automatically when the input becomes false.

How I accomplish what you are looking to do is as follows:

Hi, Thank you for your kind response.

 

Your solutions makes sense, however, it doesn't see to be carrying through for me.

Where am i going wrong?

The ton_3.q bit is only true for a single cycle so you won't see rung 14 progressing, I recommend paralleling a test bit on rung 14 so you can see what is happening. You could also latch a test bit at the end of the rung to see if the rung power is making it through when needed.

This is how i made a timer so re-triggers every second.

Oops. Just realized Photovoltaic already provided a better solution with one less tag.

Thank you to you all for being so kind as to share your knowledge and ideas to assist me. 

With a combination of your inputs, no pun intended, i have solved my puzzle. 

I used 2 timers to create a Filpflop, the second resetting the inverted input on TON.I of the first timer and visa versa

Works like a charm. 

Thanks for the help
