Monitor I/O Server Failover Status

You can configure the IBCli application to automatically switch to a different (backup) I/O Server or DAServer, if it loses connectivity to the server defined by the Access parameter. You do this within the Environment Editor by providing the Backup Node, Backup App, and Backup Topic parameters. Status information about which I/O Server IBCli is connected to (primary or backup) is made available to the InTouch HMI through system tags. Each running instance of IBCli will expose four tags available for use by the InTouch HMI. These tags cannot be used internally by AVEVA Batch Management, they can only be used by clients. The following table describes these tags, where XXXXX is the IBCli instance name.
For more information on how to use these tags in the InTouch HMI, see "InTouch Batch Tag Browsing and Referencing.".
