For information about setting up redundancy for an HMI server, see page 14-15. For
information about other server states, see “Monitoring the status of application servers”
on page 14-2.
When an HMI server is ready to be active or standby
Application servers become active or standby only when they are ready, that is, when they
are capable of accepting and processing requests from connected clients.
An HMI server is considered to be ready when:
 The server is able to provide project components, such as graphic displays and
macros.
 The server is able to receive and run commands.
 HMI tag and HMI tag alarm services are started and completely initialized.
 All alarmed HMI tags are on scan and ready to detect alarms.
 HMI tag alarm state synchronization is finished. For more information, see
“Synchronize time clocks on redundant computers” on page 14-29.
For information about when other application servers (RSLinx Enterprise data servers, for
example) are ready to be active or standby, see the product documentation, or see Help.
Specifying On Active and On Standby macros
In the primary HMI server’s Properties dialog box, in the Components tab, you can select
to run macros when the primary server becomes active or standby.
For example, you might specify an On Active macro that contains commands to run a
certain event component and data log model, when the server becomes active.
Then, you might use the On standby macro to stop those components, when the server
becomes standby.
