PLCopen is now a registered trademark: PLCopen®
It is not the intention to block the free distribution of the PLCopen specifications, which will still be available to download for free on our website. However, the international trademark registration is an important tool to protect our unique position in the market of industrial automation, as well as those of our members supporting the PLCopen specifications in their products.
PLCopen was founded in 1992 as an independent worldwide association for industrial suppliers and users. It is the leading association resolving topics related to industrial control programming. PLCopen creates concepts to reduce the costs of industrial automation. These cost savings are realized in areas such as engineering, training, operation and maintenance. Together with its members, PLCopen creates specifications to materialize these concepts.
