3.4 Fault services
3.4.1 Control monitors – List view
Description of functions
Events occurring directly in the control, or even as a result of evaluations of control
values or a machine operator's activities, can be evaluated by control monitors.
As a result, machine statuses can be acquired in order to draw general conclusions
about errors (e.g. alarms), current machine states (e.g. about accuracy determined
by circularity test), or use of resources; to collect production data (e.g. workpiece
counters); to obtain statistical data; and to analyze individual events on a
temporary basis.
The machine operator can use a control monitor to determine which signals he/she
is interested in and, therefore, which automatic tasks he/she wishes to trigger.
When the ePS system detects such an event, it can automatically trigger actions
which, in turn, trigger specific operating sequences or provide diagnostics data for
further analysis.

Note
By creating one or more control monitors, the machine operator defines the signal
or combination of signals from a machine, and predefined states on the ePS
server, that cause particular data to be generated or actions to be triggered.
