PI UK was founded in 1993 to promote the use of PROFIBUS in the UK. More recently it has added PROFINET and IO-Link to the range of technologies supported by the group and is now known as PROFIBUS and PROFINET International UK, or PI UK for short. It is a very active organisation representing the needs of members and users throughout the United Kingdom and other English-speaking countries, providing much-needed certified training in PROFIBUS & PROFINET for designers, engineers and installers. The group also presents a number of free-to-attend seminars around the country covering practical aspects of PROFIBUS, PROFINET and IO-Link in process automation as well as subjects such as functional safety and system security.
