Safety Integrated Functions
8.7 Commissioning
● Signal source forced dormant error detection (p10007)
● F-DO dynamization test cycle (p10003)
Note
For enabled Extended Functions, you cannot use F-DIs which are not used for Extended
Functions, for other functions. Although you can connect the F-DIs, Safety Integrated returns
a discrepancy error message as soon as they are activated. This is because these F-DIs are
monitored for discrepancy even when no Safety functions are assigned to them.

Selection of an input terminal for the start of the test stop: The test stop is initiated by a
0/1 signal from the input terminal and can only be performed when the drive is not in
commissioning mode.
Failsafe I/O must be tested at defined intervals in order to validate their failsafe state (test
stop or forced dormant error detection). Control Unit 305 has a function block for this
purpose. When selected via a BICO source, it executes this forced dormant error
detection (e.g. switching the sensor power supply). Each selection triggers a timer in
order to monitor the test cycle. A message is set on expiration of the monitored time.
