Carrying out a test stop:

Proceed as follows to parameterize the test stop:

1. Determine the appropriate test stop mode for the circuits used in your application (see

diagrams in the following sections).

2. Set the test stop mode which is to be used via parameter p10047.

3. Use parameter p10046 to define whether the digital output F-DO 0 is to be tested.

4. Set the debounce time for the digital inputs using parameter p10017.

5. Use parameter p10001 to set the time within which the digital output signals to the

corresponding digital inputs or DIAG inputs must be recognized.

6. Use parameter p10003 to set the interval within which a test stop should be carried out.

After this time interval has expired, you will be notified via message A01774 that a test

stop must be performed for the F-DI/DO.

7. Set the signal source which triggers the start of the test stop using parameter p10007.

This can be, for example, a control signal or switch via a BICO switchable signal.

While the test stop is being carried out, the message A01772 (test stop failsafe inputs /

outputs active) appears. The messages A01772 and A01774 only disappear again after the

test stop has been performed. If an error is found during the test stop, fault F01773 is output.

Using the test sequence specified for each test stop mode, you can see which error has

occurred from the fault value of the test step.

Duration of test stop

You can calculate the duration of the test stop by using this formula:

Test stop

= 3 · p10000 + 2 · (3 ms + p10017) + 8 · p10000 + 6 · (p10001 + p10017)
