Description of the trigger function
In terms of triggers, a distinction can be drawn between machine triggers and ser-
ver triggers:

Machine triggers respond in the form of queries for signals from the control.

Server triggers are queries for values that have already been detected on the
server and do not depend on the communication between the machine and
the server.
Any action can be executed with any trigger, regardless of whether it is of a ma-
chine or server type. Fault help requests submitted to the ePS Network Services
Internet PC and maintenance jobs that are due to be executed constitute an excep-
tion in this respect: These are monitored on the ePS Network Services server
rather than being machine-triggered.
Initiating the trigger
A trigger can be assigned a label, which determines its behavior at the central start
date for maintenance.
See Section: Editing the master data of a machine

If a label has been set and a start date, which has not yet been reached,
has been configured in the master data of the machine, the trigger will not
be initiated.

If the date has been reached or is in the past, the trigger will be initiated
according to the conditions set for it.

If a start date has not been configured, or the label has not been set, the
trigger will be initiated according to the conditions set for it.
The label for an entire trigger relates to each individual condition linked in the trig-
ger. As a result, "OFF" indicates that no trigger conditions have been linked to the
start date, while "ON" indicates that all trigger conditions have been linked to the
start date. A "faded ON" indicates that at least one trigger condition is linked to the
start date.
Machine trigger
All actions that are available in the control monitor are initiated with a machine trig-
ger. Machine triggers are initiated on the basis of either control variables or events
that take place on the control PC.
