The F-DIs must be registered for the test stop using p10041.
Note
F-DI not operational during the test
The F-DI states are frozen for the duration of the test!
• Ensure that the states of the F-DIs are not evaluated during the test.
The associated F-DOs must be registered for the test stop using p10046.
Note
F-DOs during the time period of the test stop
F-DOs, which are not registered for evaluation using p10046, are set to "0" for the duration
of the test stop ("failsafe values").
Maximum test stop time period is: T
• Testing F-DIs: T
(X = 20 ms or r10015 or p10017 - the greatest time value of the 3 values determines the
waiting time X)
• Test of the F-DOs: T
(Y = p10001 or r10015 or p10017 - the longest time of the 3 values determines the wait
time Y)
The Safety Integrated Functions of the TM54F are executed in the sampling time displayed
in r10015. This sampling time corresponds to the lowest value of the communication
sampling time entered in p10000[0..5].
Note
Manual dynamization required for specific F-DIs or F-DOs
It is possible that this test stop function cannot be used for certain F-DIs or F-DOs because
of the devices that are connected.
• Ensure dynamic operation of the affected F-DIs/F-DOs by other means, e.g. switch
operation or triggering certain machine functions.
● The test stop should be executed at a suitable point in time. This is the reason that it must
be initiated by the application or carried out at POWER ON. This functionality is
implemented using parameter p10007, which can be wired via BICO either to an input
terminal on the drive unit (CU), or to a bit of any arbitrary PZD.
