HI
this is me Zach from Amman Jordan
my ques. is there any alternative function for traditional cascading timers for single out
many thanks to you all

Hello Plastic;

What software are you using for your project, version and Service Packs? Which CPU?

What timer instructions are you using?

In which case do you need to cascade them, and why?

Could ypou provide a screenshot of your present code?

Hope this helps,

Daniel Chartier

I am not clear what you want to do.

Why are you cascading timers?  What process problem are you trying to solve that requires timers cascaded?

You can use tags that increment or count up 1 per leading edge trigger according to internal clock bits.  After the count reaches predetermined values, you compare a single counter against all values you might want to detect. 

No cascading, and the count comparison values are always synchronized, unlike timers which start whenever a scan happens to trigger the timer to start.

HI
thanks for help I do appreciate

I am working on TIA v13 . cpu 1215c v4.0
i can do programing for any timer and there related bits , address ,tags .....etcs  but i need a single function that can do timing in intervals for a single output [that can be combined in a certain FB or FC
so
i have project that needs to switch on an output  for  5s then off 5s then on 5s then off 5s . which is used for pressurizing and releasing intervals
i can do it easly in classic way but i need one FB or FC that copies the parameters to a output

thanks again

Inside an FB, you can create local timers as required to perform the on / off timing task.

You can pass a parameter for the preset time, or set it with a local constant tag.

Does that help?

thanks sir
i have tried lot of functions like shift register with counters , mux , demux , sel , functions wasn't helpful

the idea i want to use one single TON with single combined in a FUNCTION for controlling only 1 single output time interval for ON and OFF

THANKS

Hello Plastic;

I would suggest using a clock memory bit @1Hz (unfortunately, clock bits do not go up to 0.2 Hz, which would give you a single pulse every 5 sec.).See the screenshot below.

To obtain a single trigger at every 5 sec for your project, you need to adapt to the single pulse per sec. that you can get with the 1 Hz clock bit:

1 Hz clock bit --> Positive edge detection --> counter (setpoint to 5)--> reset counter and use trigger when counter reaches 5.

Every 5 sec. you will get a trigger signal from the counter that you can use any way you want in your program.

Hope this helps,

Daniel Chartier

thanks

Daniel Chartier

the output should be ON for 5s and off for 5s  THEN ---- ON 5s and off 5s and passing para. using one single TONtimer

Daniel Chartier

thanks for ur suggestion but u can not pass parameters , FIXED values only , but may be 5s ON 1s OFF or 4s ON 0.3s OFF
thanks again
