Abstract :

: In Air Separation Unit, the process control and interlocking systems are implemented by using analog signal processing cards (M/s BELLS make) and relay logics. Advancement in the field of digital signal processing opens many other features for optimized process control. These digital systems are highly reliable and it takes low down time for maintenance or trouble shooting. There are two layers of signal processing and control in this automation. Layer one is to have interface with the field and signal processing at lower level. Layer two will have graphical tools and database tools mixed with communication protocols. In this Paper an attempt is made to adapt PLC’s for the automation of Air Separation Unit.
