	Designing, implementing and maintaining process control systems for cryogenic plants requires different viewpoints compared with those in machine controls. 24/7 operations for more than a year is a basic requirement. Hardware and software must be designed to fulfill this requirement. Many projects are carried out with industrial partners.
