Software plays an ever-increasing role in industrial automation. With this,the associated software costs increase, even to the point that it?becomes the highest part of the total system. And not all costs are?directly visible: the required maintenance over the life cycle, adding?new functionalities, coping with new governmental rules.
To control these costs, one needs higher efficiency during the application?development, while increasing the software quality.
PLCopen?as an organization active in Industrial Control, is creating a higher?efficiency in your application software development and lowering?efficiency in your application software development and lowering?tools to which extensions are and will be defined. With results?like Motion Control Library, Safety, XML specification, Reusability?Level and Conformity Level, PLCopen made solid contributions to?the community, extending the hardware independence from the software?code, as well as reusability of the code and coupling to external?software tools.
PLCopen?is a vendor- and product-independent worldwide association. Its?mission is to be the leading association resolving topics related?to control programming to support the use of international standards?in this field. For this PLCopen has several technical and promotional?committees. The committees working within PLCopen are listed on?the left side.
As association, PLCopen is depending on its income through its membership?fees. For this, it supports a multi-level membership, ranging from?suppliers to educational institutes. PLCopen strongly supports the?user community. For this it created additional membership categories.PLCopen was founded in 1992 and is headquartered in The Netherlands.
One of the core activities of PLCopen is focused around IEC 61131-3,the only global standard for industrial control programming. It?harmonizes the way people design and operate industrial controls?by standardizing the programming interface. A standard programming?interface allows people with different backgrounds and skills to?create different elements of a program during different stages of?the software lifecycle: specification, design, implementation, testing,?installation and maintenance. Yet all pieces adhere to a common?structure and work together harmoniously. The standard includes?the definition of the Sequential Function Chart (SFC) language,used to structure the internal organization of a program, and four?inter-operable programming languages: Instruction List (IL), Ladder?Diagram (LD), Function Block Diagram (FBD) and Structured Text (ST).?Via decomposition into logical elements, modularization and modern?software techniques, each program is structured, increasing its?re-usability, reducing errors and increasing programming and user?efficiency.
PLCopen was founded in 1992 and has headquarters in The Netherlands with?supporting offices in the USA, Japan, and China.?
