The majority of industrial plants around the world have long since deployed microprocessor-based systems to automate the monitoring, control and protection of their equipment and production processes.  These systems include programmable logic controllers (PLC), distributed control systems (DCS), safety instrument systems (SIS) and other digital systems ranging from tank gauging systems to motor operated valve networks to electrical substation automation.  Technically, systems could also include field instrumentation and control valves.  Owner/Operators have been enjoying the benefits of the digital revolution since the mid-1970s – longer equipment life, extended run length between turnarounds, increased plant throughput, higher profit margins, reduced manpower, improved operations and personnel safety and easier compliance with government regulations.  By and large these systems have delivered reliable operation over the years and become an almost forgotten part of a plant’s critical infrastructure. Unfortunately, many of these microprocessor-based systems are beginning to show signs of age and failing to meet...
