Cycle manager enables you to model a process by breaking the process down into stages. You can use expressions to determine when each stage of the process is active.
Some of the benefits of cycle definition include:
-
Capture of Downtime events for each stage.
-
Capture of Downtime events for stage overruns and assign specific causes and classifications.
-
Enables AVEVA Production Management to change the active stage based upon configured conditions.
-
Enables operators to change the active stage.
Example of using Cycle Manager
A company runs a "glassline" that packages an instant coffee product, 24 hours a day, 7 days a week. (The "glassline" is the general name of the production line that puts instant coffee powder into glass jars.) When scheduling operations, the company tries to minimize the number of line stoppages due to cleaning or setup changes (refitting machinery to facilitate a change in glass size).
The changeover/cleaning stoppage generally includes the following stages:
-
The production line stops when last order is finished.
-
Operators clean the bin-tipping area through to the filler (remove traces of the last powder product).
-
Various teams begin changing the conveyor guard sizes, filler heads, capper heads, label types, and packaging at the end of the production line.
-
The production line runs slow to check that the changeover is successful.
-
Resume full production.
Each stage in the process of a product changeover takes only a certain amount of time. During this changeover, AVEVA™ Production Management could capture the finished maintenance activities.
Key concepts
Cycle manager comprises three concepts: cycle managers, cycle definitions, and cycle stages.
-
Cycle manager defines the relationship between multiple cycle definitions (Operating and Cleaning) and a piece of equipment (Packing Machine). When you define cycle manager, you create cycle stages for each stage in the associated cycle definitions.
-
Cycle definition is a process cycle (for example, operating or cleaning) and the stages it encompasses (for example, isolate, tag, blind, online, and offline).
-
Cycle stage is a specific instance of a stage in a cycle for a piece of equipment. You can define rules for when it becomes active (operator-initiated or system-initiated) and for how long the expected duration of the stage is.
