Research Triangle Park, NC (12 May 2005)- OMAC - The Open Modular Architecture Controls Users’ Group- announced recently the release and distribution of the PackSoft Application Library (PackAL). “This standard will give users more transparency in machine programming, debugging and maintenance and allow the user to move toward standardized ways of exchanging information in between machine module controls,” explained Gerd Hoppe, CTO North America, Beckhoff Automation.
The document, now ready for implementation and testing, is distributed as a Technical Paper and includes: graphical timing diagrams describing the performance of function blocks, function block control inputs and naming conventions for easier programming and handling, and the addition of the PackML State Machine Function Block as an interface standard to State Machine implementations. Additional topics covered include best practices on implementation of applications, generic function blocks for machine to machine communications, a compliance declaration section, and the new PackAL logo.
The work of PackSoft will continue to further develop the document, and the group intends to issue a future version with improvements, user feedback, and alignments with future PLCopen standards currently in draft status.
About OMAC
OMAC–The Open Modular Architecture Controls Users’ Group ( www.omac.org ) is an affiliate organization of ISA- The Instrumentation, Systems and Automation Society- and works to collectively derive common solutions for both technical and non-technical issues in the development, implementation, and commercialization of open, modular architecture control (OMAC) technologies, and to facilitate the accelerated development and convergence of industry and government developed OMAC technology guidelines to one set that satisfies common use requirements. OMAC has about 500 member representatives from end-user companies, OEM's, and technology providers and integrator companies. OMAC currently operates three Work Groups: Packaging Machinery, Manufacturing Infrastructure, and Machine Tool.
