PackML

PackML stands for Packaging Machine Language. The Packaging Machine Language is a machine-to-machine communication standard defined by the Organization for Machine Automation and Control (OMAC). It is used in machine control systems, including the packaging industry. The standardized programming language simplifies the control and maintenance of machines and facilitates the integration of all devices into an automated manufacturing system. It optimizes production processes and reduces downtime.

PackML gives packaging machines a consistent look and feel for the operator. It simplifies integration and makes the software easier to expand and diagnose. The ISA standard TR88.00.02 defines a state machine, some modes and naming conventions for variables within the standard. This allows a uniform interface to be implemented externally, the so-called PackTags.

The state machine defines 17 states in which the machine can be and thus controls its sequence. Within the state machine, clearly defined structures must be adhered to when writing the machine code.

The Mode Manager manages the operating states of the machine. These can be, for example, automatic, manual, maintenance or cleaning. It is also possible to define various manufacturer-specific operating modes. The Mode Manager checks whether a change between the operating modes is possible - or even permitted - depending on the current status of the machine.

The PackTags are the interface to the outside world. The relevant machine data is stored in them and can be used for horizontal integration (e.g. with other machines) or for vertical integration with higher-level systems (e.g. MES or ERP). They include admin, state, and directive tags. Machine information such as the current speed, status, operating mode and much more can be read out. Extensive alarm management is also included.
