Field Content

Remaining
performance
Shows the number (only in the case of
bytes) of PLC variables that can still be
used in triggers and as a condition. De-
pending on the size of the variable, it may
be that 2 counts for one variable.
DISPLAY

settings
Since the PLC data blocks are required for
the "PLC variable" trigger, it is possible to
branch directly to the "PLC settings" menu
from here.
ACTION
Each trigger can be assigned a label, which determines its behavior at the central
starting date for maintenance (see also: Sub-section 6.1.3 "Machines"
Æ
Master
data, and general description of triggers):
•
If a label has been set and a starting date, which has not yet been reached,
has been configured in the master data, 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 starting date has not been configured, or the label has not been set, the
trigger will be initiated according to the conditions set for it.
"Icons" tab
The absolute address can be edited under "Icons".
Field Content

Icons
Displays the list of ANDed comparison
operations in the trigger (in relation to the
absolute addresses). These can be
selected individually for editing purposes.
TAB
Edit absolute
address
Data type
The system does not support plausibility for
the absolute addresses, their data types, or
the possible comparison operations.
Notice:
Subsequent correction of the absolute ad-
dress data type is not possible. The vari-
able must be deleted in its entirety, along
with its comparison operation, and a new
variable created.
INPUT
DISPLAY
Force absolute
address
To make it necessary for the trigger logic
operations and comparison operations to
be manipulated by deleting entries that
have already been made (for testing pur-
poses) each individual address can be
forced, i.e. the address does not participate
in the AND logic operation of the trigger.
