Response times Safety Integrated Basic Functions

The Basic Functions are executed in the monitoring clock cycle (p9780). PROFIsafe
telegrams are evaluated in the PROFIsafe scan cycle, which corresponds to twice the
monitoring clock cycle (PROFIsafe scan cycle = 2 × r9780).
Controlling Basic Functions via terminals on the Control Unit and Motor/Power Module
The following table lists the response times from the control via terminals until the response
actually occurs.

Controlling Basic Functions via Profisafe
The following table lists the response times from receiving the PROFIsafe telegram on the
Control Unit up to initiating the response.
