rudolfzikmund Posts: 6 Rating: (0)	Hello, i have the problem with timers in the loop FOR. My program reads array of char and compares char by char with other chars from DB. And if is the char for example 0 timer starts and its output is true, and in this moment I need to let the timer works and after the timer has done I need to do next round with the loop FOR. In this moment loop FOR reads first char, timer starts but loop FOR has done and timer is still working with the first char. I really do not know how to do it. I do it in the SCL. I tried to do it by time interruption, but I am no sure if I understand correctly how to do it. Thank you for help

I think the best way is to provide your code here fot better understanding Your code is in SCL, so you can easily use this: [code]Here you can write the code [/code]

Please check the answer fromWilliam B.You should not use timers inside LOOP, I do not think it is good solution. I case of true comparison just set some flag and outside of the LOOP start the timer (eventually skip from the LOOP if you want to ...). Regards.

But during this(when timer works) loop FOR will be in the end right? You will skip from the LOOP, start the timer. Second call of these part of code - you will enter the LOOP again - it is up to you how do you want to do it. If you want to go the LOOP again or after timer is gone etc... Regards.

Mean while please find attached a sample program with timer and loop. Here I have used a IF else statement along with counter. In the similar way you can also implement it using FOR loop as well. My application was to keep open n no. of valves sequentially for a specified timer. Attachment C:\Users\in213755\Desktop\Timer_loop.zip (608 Downloads)

I expect, that after timer will be finished db1.actFlag= false and program will do next round. Instead the program change stats db1.actFlag= true but freeze.
