The settings you specify in the Redundancy tab for the primary HMI server are saved with
the application, and are the same for both the primary and the secondary server. No further
setup is required on the computer hosting the secondary server.

For more information setting up redundant HMI servers, see Chapter 14, Setting up
FactoryTalk system availability.

Replicating changes to the secondary HMI server

In a non-redundant FactoryTalk View SE network distributed application, you can modify
tag properties and alarm conditions (after issuing AlarmAcceptEdits) at run time, and
have those changes take effect at connected clients, without restarting the clients.

In an application containing redundant HMI servers, you can replicate HMI application
component changes made at the primary server to the secondary server. For details, see
page 14-17.

Selecting startup and shutdown components

In the Components tab of the HMI Server Properties dialog box, select the check box for
each of the items you want to run when the HMI server starts or stops, including:

Which components will run when the HMI server starts up.

Which macros will run when the HMI server shuts down.

Which macros will run when the system switches to the secondary HMI server, or
back to the primary HMI server.

Where required, specify the name of the component. For details about options in the
Components tab, click Help.

For information about macros, see Chapter 24, Adding logic and control.

Running a macro when the HMI server becomes active

The macro that runs when an HMI server becomes active is called the On active macro.
An HMI server can become active if another HMI server fails, or if it is the active server
at startup time.

Any FactoryTalk View macro can be used as the On active macro. If you have not set up a
secondary server in the Redundancy tab, the option to run an On active macro is not
available.

The order of items in the Components tab is not the order in which the items will run when the
HMI server starts up. If components must run in a particular order, create a macro to start the
components, and then select the macro to run when the HMI server starts.
