Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
The F-DIs must be registered for the test stop by means of p10041.
Not e
F-DI not operational during the t est
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 corresponding F-DOs must be registered for the test stop by means of p10046.
Not e
F-DOs during t he period of t he t est stop
F-DOs which are not registered for evaluation by means of p10046 are set to "0" for the
duration of the test stop ("fail-safe values").
Maximum test stop period: 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 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].
Not e
Manual dynamization required for s pecific F-DIs or F-DOs
It may not be possible to use this test stop function 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 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.
