6.7.3 Programming Safety Functions with Siemens TIA Portal
Refer to the Siemens documentation for more information on distributed safety. Refer to the following documentation for informa-
tion on how to use safety inputs and outputs for passivation and reintegration.
• Industrial Software SIMATIC Safety - Configuring and Programming. Programming and Operating Manual.
• Fail-safe Controllers SIMATIC Safety Integrated. Emergency Stop with Acknowledgment in Category 4 according to EN 954-1.
•
Fail-safe Controllers SIMATIC Safety Integrated. Passivation and Reintegration of F-I/O considering as example the ET 200S.
6.8 Reset Function
When the safety function is activated, reset the safety option. Depending on the configuration, the following sources can reset the
safety option:
• The [Reset] key on the LCP or the drive's digital input.
• The reset signal via the safe fieldbus.
Parameter 42-24 Restart Behavior determines whether the safety option restarts automatically, or waits for a manual reset after the
safety function was activated:
• Manual reset behavior - when the safety function is activated, the safety option requires a reset from a reset source before it can
run again.
• Automatic reset behavior - when the safety function is activated, the safety option can run again when the condition that trig-
gered the safety function ceases. This behavior is only valid for the digital input where this reset behavior is defined. For in-
stance, if there is an external error, a manual reset from the reset source is required regardless of the setting in Parameter 42-24
Restart Behavior.
For more information, read the description of parameter 42-31 Reset Source.
