Parameters
12.2 Description of parameters
Limit monitoring
Enable the monitoring of the limit for a freely definable measured value here. Limit violations
are counted and the count values stored retentively.
Measured value ID for limit
Enter the ID of a measured value that you want to use for limit monitoring.
Limit gate via DQ
Enable the gate via DQ here. When the gate is enabled, the limit monitoring is only started
when the corresponding bit of the associated output user data is set to "1".
Hardware interrupt for limit
Enable the hardware interrupt here. The hardware interrupt is triggered if a high or low limit
is violated. Without activation of a hardware interrupt, a limit violation is only displayed in the
user data and in DS 150.
Limit
Enter the limit here that is to trigger a limit violation when exceeded or fallen below. Limit
violations are displayed in the user data and in DS 150.
Type of limit
Select here, whether it is an high or low limit. Depending on this selection, the limit violation
or hardware interrupt is triggered when a value exceeds (high limit) or falls below (low limit)
the limit.
Hysteresis for limit monitoring
Enter the hysteresis for limit in percent here. The percentage refers to the numerical value of
the limit when the limit violation occurs. A message is only canceled if the measured value is
outside the limit and its hysteresis range. As long as the measured value is in the hysteresis
range, no new message is output.
Delay time for limit monitoring
Here you can select the delay time for limit violation. The delay refers to the time that must
elapse before an occurrence of a limit violation is reported. Faults can be filtered out by
selection of the delay time. The deceleration time is also taken into consideration during
outgoing of the limit violation.
Number of measured values for user data mapping
Specify the number of measured values/variables that you want to use for the user-specific
user data mapping.
Measured variable
Select the measured variable (with the measured value ID) that you want to use for the user-
specific user data mapping.
