Response times that use measured value
Measured values are calculated and updated by the module to the F-CPU at the rate specified
by the configured "Update time". Safety reaction times that use measured values in your
safety program (for example, SLS) are therefore dependent on the configured update time.
Refer to Measured value determination (Page 16) to calculate measure values.

Internal cycle time of the fail-safe module
Internal diagnostic repetition rate
One Fault Delay Time: Maximum response time for the fail-safe module to report a
channel as passivated
Maximum transition time of the signal monitoring error output
Worst Case Delay Time: Maximum response time from a signal transition at the
fail-safe module's counter input to the reliable availability of the safety message frame
available for the fail-safe CPU request
