Safe Response Time of Digital Power Outputs
For the safety response time, take into account the execution times of the
local bus, fieldbus and cycle time of the safe PLC!
To prevent personal and property damage, take into account the execution times
of the local bus, fieldbus and cycle time of the safe PLC in calculating the safety
response time.
The safe response time of the digital power outputs indicates the time from an
incoming PROFIsafe telegram to the local bus to the signal change on the digital
power output. It is part of the overall response time of a safety application.
The safe response time of the digital power outputs depends on the protective
circuit used and the test pulse length configured. You can set the Test pulse
parameter in stages using the WAGO parameterization tool. For more
information, read the section "Parameterization of the F I/O module with the
WAGO Parameterization Tool".
The following table lists the safe response times for the digital power outputs
based on the test pulse length and the protective circuit used.
