PackML, or the Packaging Machine Language, is a set of industry standards created for use in industrial automation. Primarily, the PackML standard is used for packaging applications, but can be applied to machines in any industry, including pharmaceuticals, or food and beverage manufacturing. PackML was designed to bring a standardized ‘look and feel’ to machines, which would offer cross-industry consistency and make it easier for operators to quickly learn and work on PackML compliant machines, as well as quickly integrate whole lines of machines.
The basic requirements of PackML machines are: standard defined machine states and operational flow, Overall Equipment Effectiveness (OEE) data, Root Cause Analysis (RCA) data, and flexible recipe schemes and common SCADA or MES inputs.
PackML was developed by the ISA (International Society of Automation) S88 Committee in the 1980s. ISA S88 Part 1, Batch Control Models and Terminology, first presents suggestions for a hierarchical model with modular software design.
Later, the ISA began developing industry standards for Batch Control markets, with a focus on increasing efficiency through standard controls and procedures. ISA-S88 Part 5 (Make2Pack) was released for the Batch Control industry. By the 2000s OMAC (Organization for Machine Automation and Control) was working on a competing standard that employed the same basic concepts of Make2Pack for the Machine Controls industry, specifically for packaging machines. These standards were developed separately until 2008, when an ISA technical report, ISA TR88.00.02-2008, sought to merge them. Machine and Unit States: An Implementation Example of ISA-88 formed the basic platform for the Packaging Standard that would be known as PackML.
The focus of PackML was rapid integration of a line of machines that might all be using a different Fieldbus, SCADA and MES. Later in development, PackTags were introduced to provide a uniform set of naming conventions for data elements. PackTags are used for machine-to-machine communications, and were designed to incorporate OEE data.
During PackML development, PackTags were included in the guideline documents. The 2008 version (v3), contains both PackML and PackTags, which were harmonized with the ISA-88 standard terms and definitions to produce the technical report ISA-TR88.00.02-2008 Machine and Unit States: An Implementation Example of ISA-88.
