Alarm Server Definitions

Refer to the default server port numbers under Configure Servers.

Note: The Alarm server reuses the Alarm Properties port. As a result alarm properties are now published for configured alarm servers.

To configure an Alarm Server:

  1. In the Project Editor, choose Servers | Alarm Servers.
  2. In the Alarm Servers dialog box, complete the properties:
    Option Description

    Cluster Name

    The name of the cluster to which this Alarm Server will belong. If there is only one cluster defined in the project, you can leave this field blank. The Alarm Server will default to the defined cluster

    Server Name

    The name of the server. The name needs to be unique to the project and any included projects, and not contain spaces.


    The mode for this server, either Primary or Standby. If this property is left blank, the default value will be Primary. The Primary and Standby servers need to run on different computers, and only one Primary and one Standby can be defined per cluster.

    Network Addresses

    The network address(es) of the server being configured. To specify dual network connections to the server, use a comma delimited list. See Network Redundancy.


    The port this server will listen on. You can leave this field blank if you are running only one Alarm Server on the machine, in which case the default port number will be used.


    Any useful comment. This property is optional and is not used at runtime.

    Extended forms fields

    The following fields are implemented with extended forms (press F2).

    Note: Servers listen on legacy ports only if the INI parameter [LAN] EarliestLegacyVersion has been enabled.

    Option Description

    Legacy Port

    Allows legacy connections to the server

  3. Click the Add button to append a new record, or Replace if you have modified a record.
