2 Machine information
2.3 Test series on the machine
2.3.3 Prolog and epilog program for a measurement
Description of functions
To prepare the control making it suitable for the test, an NC program that has been
specially adapted to the machine by the machine manufacturer or end user is exe-
cuted at the beginning of the test. This means that machine settings can be specifi-
cally changed so that the test can be performed (example: Disabling transforma-
tions and couplings, resetting pre-set G codes).
Suitable programming of the prolog and epilog program can influence how the test
is performed. When a test series is carried out, individual measurement series can
only be hidden under the tested conditions (e.g. due to a risk of collision).
The prolog and epilog program is reloaded into the control with name
"N_EPS_PROLOGEPILOG_SPF" every time a test is run. The NC program editor
of the operator panel (=HMI-Advanced) can be used to modify this program.
After the test has been performed, the ePS system automatically checks whether
the prolog/epilog program has been changed and, if required by the machine op-
erator, stores it permanently.
