Held

The Held bit is an optional status value that can be generated and used within the control system to keep track of the status of a particular unit. Generally, the Held status bit is enabled only after the unit Hold bit has been received from AVEVA Batch Management System. When the Held status control relay is enabled, none of the remaining unit status bits should be set.

This status bit is used only within the control system program and is not monitored by the batch control system.
