PackTags provide a uniform set of naming conventions for data elements used within the procedural elements of the base state model. They are named data elements used for open architecture and interoperable data exchange in automated machinery.
The library provides the PackTags, as defined in ANSI/ISA TR88.00.02-2022.
The variables are grouped into three types:
|
PackTags type |
Description |
In the PackML Library |
|---|---|---|
|
command |
These variables mainly represent the control interface. By using these tags, operation modes can be selected, state transitions can be forced, and recipes as well as formats can be transmitted. |
ST_Command |
|
status |
These variables contain status information (such as which operation mode is active, which state is active, and so on). |
ST_Status |
|
administration |
These variables contain important OEE data (for example, downtime, reasons for downtime, and so on). Furthermore production information. |
ST_Administration |
The individual variables from the three types (command, status, administration) can be provided on the controller within the structures.
