I want to use SFC43 in OB1 -How do this?

Hello friends 

In machine, has a CPU 314-2DP that is watchdog problem. The scan cycle time is greater than 150 ms, but i not can change scan cycle time in CPU properties because i not have drive e/s software and simotion for download hardware after changes.

I include in OB1, SFC43 for my CPU not change to stop.

My doubt, where i include sfc 43 in ob1 for cpu not stop per watchdog?

Obrigado...../Gracias...../Thanks.....

 Hello,

 In OB1 you can before scan time (look below), but pay attention to safety when you will do it , if you're so high cycle time I do not know if it will be the solution , however, before you go online to the CPU in OB1 to see if it's OK , but always think of the safety of persons

Please have a look:

Hi,

look in the Sysem and Standard Function Manual.

Here are some informations about SFC43 / Controlling Program Execution (Chapter 4).
