2 Machine Information
2.3 Test series on the machine
2.3.6 Release protocol between PLC and ePS system
Function description
Communication is performed between the ePS system and the PLC for the execu-
tion of a test. The ePS system signals that a test will be executed with axis move-
ments. 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 sche-
dule to be executed in a fully automatic manner while being monitored by the PLC.
More details are given in /R1/.
2.3.7 Contour test
Function description
A dry run is possible to ensure measurements can safely be performed on the ma-
chine. The machine operator has the option of executing a dry run with reduced ve-
locity before beginning the test run configured to a specific type. This allows the
operator to test for safety path motions (contour monitoring) of the machine axes to
avoid collisions, etc.
