Series 90 TCP/IP Triplex Enabler used with Server Redundancy

The Series 90 TCP/IP Triplex enabler is among the communication interfaces that are supported in CIMPLICITY Server Redundant configurations. The enabler on the standby node will heartbeat all communication paths of the configured devices. If a problem is detected, an alarm will be generated to indicate the communication path in error.

On the Primary Server, alarms indicating individual communication path errors are NOT generated automatically. Diagnostic points that indicate the status of the individual paths can be configured to have an Alarm condition. Since diagnostic points do not reflect the status of the communication paths on the Standby Server, the enabler on the standby node generates alarms to reflect status.
