Time delay (in seconds) for the evaluation of process alarm. Process alarm is raised, if a cause of raising the alarm is valid at least within this period.
Note: the time delay is applied only to status alarms - transition alarms occur immediately when the value is changed.

Start value is saved in a text form. During the system start, the Server assigns values to individual objects according to the start value definition. In case of the successful conversion of a start value (text) to the required type, a value of the eval tag will be valid. If the conversion is not successful, then this value will be invalid. It is possible to save a start value that cannot be converted to the required type. The button Start value checkout (Image RemovedImage Added) checks the start value and, in case of unsuccessful conversion, reports it.

The parameter can be defined for the evaluation method On change. It allows restricting the evaluation of a given expression so that the expression will be evaluated once within the defined time. It is used especially in cases when the values of the objects defined in the expression are often changed and immediate calculation of the expression is not required.

Note: entering a negative value sets the maximum density of evaluation in milliseconds. For example, the value -150 means a maximum of one evaluation per 150 milliseconds.
