An example for calculating the local cycle times is given here for clarifica-
tion.
There are three programmable controllers, each with a CP 541 and intercon-
nected via SINEC L2.
The message traffic between the two failsafe programmable controllers is
safety-related. Four bytes for data security are present per safety-related mes-
sage.
