## General

#### Process variable

Name of the selected process variable

#### Active

Activate/deactivate individual process variables or the process variable group.

#### Range limit shortfall

Notification of range limit shortfalls

#### Range limit exceeding

Notification of range limit exceedings

#### Value monitoring

Cross-check of the current value against a fixed value. The standard comparative operators (=, <>, <, >, <=, >=) are available for this comparison.

Note

For the operators = and <>, the 'Current value' field can be left blank, so then the cross-check is made against 'NoValid' (no value available).

#### Use predecessor value

The predecessor value is used instead of the current value.

Note

By using this option, you can prevent values that have not yet been fully calculated (current interval value of a not yet completed interval) from triggering a notification.

#### Notification

An individual message text can be created for each trigger condition. Various placeholders are available for this:

* $ShortName - Identification of the process variable
* $LongName - Name of the process variable
* $Val - Value of PV at time of check
* $ValLim - The comparative value for monitoring
* $UpperLim - Upper limit value (for the selected analysis level)
* $LowerLim - Lower limit value (for the selected analysis level)
* $TimeStamp - timestamp of the value for which the notification was first triggered.

#### New entry

Selection of process variables to be monitored.

#### Delete entry

The selected process variable is deleted.
