selection of alarms to be logged can be reduced to those alarms that are relevant for the
specific test step.
Internal trace function to record signal characteristics
The SinuCom NC internal trace function is started when the data trace is started and the
signals, relevant for the specific test step, recorded. The trace is either automatically ended
or the user ends it for some tests (external stops, Emergency Stop).
Specific NC machine data must be set in order that the trace function can be used. This
prepares the appropriate resources for the function. The values to be set should be taken from
the SINUMERIK SinuCom NC start-up tool.
Basic operating information and instructions
● The operator is prompted, step-by-step when carrying out a test. The following limitations/
constraints must be observed, especially for those tests that use the internal trace function:
– If a traversing direction has been selected, then this must also be taken into account for
– A procedure is initiated to activate the trace function using the button <start data
– If the trace has to be manually terminated, then this step should, if at all possible, be
● For each test step, the operator must decide as to whether the test was successfully carried
out. He should make this decision based on traced and determined data and test situations
that have been carried out and documented. This can be confirmed after the test has been
carried out by selecting the appropriate results.
● The test list, provided and supported by SinuCom NC includes the basic test steps to be
carried out. Depending on the machine configuration, several tests may not be necessary
for the particular machine. This can be selected in the basic screen of the test step. Further,
there are test cases, that are required for the machine but are not (or still not) included
within the scope of the test list, e.g. measuring the braking travel when a light barrier is
obstructed, or similar. These tests should still be manually performed.
● When generating the acceptance certificate, for documentation purposes, data is
automatically retrieved from some machine data (SI limit values, checksums, hardware
information).
Further, the results of the tests that were carried out are incorporated in the document. The
report is structured the same as the document that was previously manually created. Some
sections, such as for example, the machine overview, function table of the configured safety
functions etc., that are not standardized, are still manually incorporated in the document at
a later date.

the subsequent task. The reason for this is that the trigger condition for the automatic
data acquisition and evaluation is based on this direction data.

appropriate feedback has been received in a message box.
made directly after the last expected signal change that is relevant for the trace. This
ensures that the relevant area is optimally displayed in the subsequent trace display.
