Ive now achived to place my block into the ob10"Day of interupts". This is the and block on the attachment. 

How the "Day of interupts" should work for me, is give a positive edge (blinking pink line) to clean 1 block x4.

I would presciate any helpfull answers. this nut is really driving me mad!! =)

best regards

Hello,

To enble executing OB10, you have to activate it in HW configuration and make the rule that the OB will be executed based on (When you want the OB 10 to be executed? Every minute, hour, once a day,...etc) and also the starting date and time for execution. Do not forget to adjust time and date of your CPU and also you have to mark the check mark "active"

Hope this helps.

The problem is when the the time is reaced for the ob10 daily interupt nothings happens....

Hardware config is ok.

clock adjustment is ok.

what else can be wrong ?

I only need a positive edge into my block from the and block. 

So if I am not wrong, you need a pulse on certain marker  to be high once per day (during time of day HW interrupt ) "OB10". Am I right?

And then this bit should be reset. And your problem now is that this bit is always high. Am I right?

So there are more than one solution assuming that the bit is "M15.0".

Well i made myself a memory called M10.5 and stored it in the symbol table as " interupt memory".

Futher on in ob10 i have the following sentence: 

and in the 

ob1 i have the 

In the CFC diagram i just make a connection to the memory "Interupt Memory" (attachment pink line)

It still Doesnt work ????? clock and interupt are check and uploded to the plc.

I've finaly come to end to my problem with my ob10. I guess the 24 Hours clock on my computer and the 12 hours clock on the cpu confused me..

Anyway i really want to understand how the we can make this with the run mode in cfc chart.

Ive added a SR flip flop and want that to send out a signal when the ob10 time of interupt occurs (ex 10.00)

The SR flipflop are added in the ob10 Run mode in cfc chart. But nothings happens when the time of interupt occours.

Anyway when i go into the ob10 and see it online there is something that is set "true".

Can anybody help me understand whats is set "true" ?

Oystein.

I would be gald if someone gave me an example =)
