how to distinguish cycle time

Hi,

E.g. the Safety part are called from a individual OB.
You can have a general load distribution vision whit help of some code. 

There are examples avaliable in 

For S7-1200/S7-1500, how do you measure the runtime of the complete program, subprograms or specific organization blocks?

Hi,

as default, that means with "automatic calculation" enabled, the load will never be greater as 50% of the CPU's port capacity (that means will never be greater as 50Mpbs).

The  S7-1500;s web page shows the communication load for other communications (TCP, S7, etc.)

Hi,

in this case, you can place timers and count how many time takes the OB execution / how many time takes to a OB will be called again.

TIP: the PROFINET load doesn't affect the OB's execution time.

Use the RUNTIME instruction.  There are forum topics as well as Portal F1-Help and Siemens sample project showing how to use every instruction and the code required to use it.

Good morning everyone, in a CPU 1215F, in which Profinet and profisafe data exchange is used, how can I know how much the cycle time load is for each part?

In practice I can only see the total cycle time, but not that relating to the profisafe part and that to the profinet part.Is there a way to know?

Thanks for any reply
