2.3.5 Commissioning measurements
Description of functions
The prolog and epilog program must be edited in order to perform measurements.
If measurements are performed on a machine for the first time, or if the prolog and
epilog program has been deleted, then a preconfigured prolog and epilog program
takes effect, which prevents the further execution of the NC programs as the NC
program code runs in an endless loop. This part of the preconfigured prolog and
epilog program must be deleted. A program code adapted to the requirements of
the machine must be used for the prolog or epilog.

2.3.6 Release protocol between PLC and ePS system
Description of functions
Communication is performed between the ePS system and the PLC for the
execution of a test. The ePS system signals that a test will be executed with axis
movements. The PLC can then put the machine in a suitable state and signals to
the ePS system that the test can begin.
The protocol allows test series that are to be carried out with a maintenance
schedule to be executed in a fully automatic manner while being monitored by the
PLC.
More details are given in /R1/.
