Configuration of the alarm server

In addition to the pure monitoring of alarm statuses, the alarm server offers the following additional functions:

• Alarm history

  It manages an alarm history in the form of a database. All alarm status changes that occur can be saved in it. The decision as to which alarms are to be saved is made using the Save parameter in the alarm class definitions.

• Online alarm line printing

  It enables online alarm line printing, i.e. all alarm status changes that occur are sent directly to a connected printer in the form of print control characters via a parallel port on the server computer. The decision as to which alarms are to be printed is made using the Print parameter in the alarm class definitions.

The configuration of the alarm server essentially enables the following project-wide settings:

• Configuration of the alarm history

• Configuration of the runtime behaviour

The configuration is visible via the project explorer node AlarmsWConfiguration on the property pages.

• Components of the Alarms system module

• Alarm states
