hello,

i m working on project using tia portal v13  with 1200 cpu ,im having problems with timers in the fb (TON timers ),the thing is when i call the fb countaining the timer several of times it doesnt work (i used the multiinstance but still the same problem) can any one help me please

What timers are you using? 

If you're using S_ODT, S_OFFDT etc timers - each timer has to have its unique number 

it's a TON timer retard a la montee so it a ;on delay timer

Hi,

is it the behaviour described in the follwoing FAQ?

Why is the Online status of the timer not updated in STEP 7 (TIA Portal)?

Regards,

Towome

Hi,

Your FB5 block should also have a different instance data block for each block call.
