Safety Response Time

For the safety response time, take into account the execution times of the
local bus and fieldbus, as well as the cycle time of the safe PLC!
To determine the safety response time, always take the execution times of the
local bus, fieldbus, sensors and actuators and the cycle time of the safe PLC into
account when calculating the safety response time.
3.6.9.1

Safety Response Time of the Digital Inputs

The safety response time of the digital inputs specifies the time between when a
signal change occurs at the digital input and the PROFIsafe telegram at the local
bus is sent. It is part of the overall response time of a safety application.
3.6.9.1.1 Safety Response Time of the Digital Inputs for Single-Channel
Applications
In case of single-channel use, the safety response time depends not only on the
test pulse duration and the input filter time of the input channel in question, but
also on the input filter time of the other input channels. The dependency is
illustrated in the following table:
