Security Area for Enhanced Failover
If iFIX security is enabled, you are encouraged to use a security area to restrict manual SCADA node role switching to specific users. One security area is supported for Enhanced Failover. This security area can be assigned to authorize users of your Enhanced Failover configurations through the System Configuration Utility (SCU). The Enhanced Failover security area can be set on either or both the primary and secondary nodes; however, it is recommended to use the same security area on both nodes in your Enhanced Failover configuration. With the security area configured, you can prevent unauthorized manual SCADA node role changes that are performed locally or remotely. For example, you can prevent specific users from enabling Maintenance Mode.
The Enhanced Failover security area is checked when enabling and disabling Maintenance Mode from the SCADASync tag and when manually switching SCADA roles from the NSD tag.
To assign a security
area for Enhanced Failover:
- In the SCU of the primary or secondary node, on the Configure drop-down menu, click SCADA. The SCADA Configuration dialog box appears.
- In the Enhanced Failover Security Area field, enter the security area name.
- Click OK.

For more information on the SCADA Configuration dialog box and configuring a node with the SCU, refer to the Setting up the Environment e-book.
