The OMAC Users Group was formed in 1994 as an organization for companies to work together and:

* Collectively derive common solutions for both technical and non-technical issues in the development, implementation, and commercialization of open, modular architecture control (OMAC) technologies.
* Promote OMAC development among control technology providers and OMAC adoption among end users, OEMs, and system integrators.
* Act as a repository for OMAC requirements and operating experience from users, software developers, hardware builders and OEMs in manufacturing applications.
* Facilitate the accelerated development and convergence of industry- and government-developed technology guidelines to one set that satisfies common use requirements.
* Collaborate with users groups around the world in pursuit of common international technology guidelines.

We currently operate three Working Groups: Packaging Machinery, Manufacturing Infrastructure, and Machine Tool. These groups lead the way in producing consensus guidelines to improve flexibility, improve capability, and reduce system integration costs. We also seek to improve the automation industry’s capabilities by defining the educational and training needs of our community.

OMAC has about 500 member representatives from end-user companies, OEM's, and technology providers and integrator companies. These members include companies with vested interest in developing and implementing open control technologies for manufacturing applications.
