Configuring the event counter
Requirement
You have configured the following values in limit monitoring:
● Upper limit
● Lower limit
● Hysteresis
Configuring limit monitoring (Page 154)
Procedure
1. In the "Limit" text box, enter the number of underrun and overrun events that must be
reached in order to trigger the action for underrun and overrun respectively.
2. From the "Action" drop-down list, select whether process value alarms or warnings
(maintenance demanded and maintenance required) are triggered.
– If you set the action to "Disabled", no new process value alarms or warnings for the set
limit values are triggered, although the counter remains in operation.
All process value alarms and warnings that were triggered before the action was set to
Disabled remain pending until the event counter is reset.
3. Click on "Transfer".
Result
The configured diagnostics are triggered after the specified number of limit violations has been
reached (e.g. Maintenance required).
Process value alarms and warnings are displayed as symbols for the status in the "Diagnostics
> Device state" dialog in the engineering system and on the device screen.
These process value alarms and warnings must be acknowledged.
