Define Equipment Status (Equipment Status Tab)

Use the Equipment Status tab to define, edit, and delete process model statuses for units and segments. Equipment Status names must be unique. If you attempt to enter a duplicate name, a message indicates that the equipment status already exists. Deleting an equipment status item can affect other portions of your process model.

Equipment statuses represent the various states that a unit or segment can possess at any point during the process. You must define one default status. The default status defines the initial state that the AVEVA Batch Management System assumes for all of the units and segments. All status changes are recorded in the History database.

A system tag is automatically generated for each unit or segment that you define in the process model. The equipment statuses define the possible values of this system tag. The statuses are used by the AVEVA Batch Management System when it evaluates the availability of a unit or connection.

The availability of a unit is determined by the current status. If the status is set to available, the AVEVA Batch Management System can allocate the unit. If the status is not available, the unit cannot be allocated.

The availability of a connection is determined by the current status of all of the segments that comprise the connection. If a connection does not contain one or more segments, the connection is always available.
