UL (Underwriters Laboratory) standard UL covers testable cybersecurity criteria and NIST (National Institute for Standards and Technology) has been creating an Industrial Control Systems security framework to protect critical national infrastructure, 90% of which is under private control. ![]() IEEE (Institute of Electrical and Electronics Engineers) standard C37.1 provides SCADA and automation requirements for power substations. Organizations including the International Society of Automation (ISA) provide control system standards, training and design guidance. Industrial networking standards such as the Common Industrial Protocol (CIP) for network communication provide interconnection between system components. Interoperability is the key to process control system design, reliability and safety. ![]() Versatile sensors, controls and communication equipment let process engineers create a solid, reliable way to get work done. The process can be limited to a laboratory environment, expand across a manufacturing floor or use wireless technologies to integrate oil and gas operations in the field. ![]() Like a complex railroad diagram, the HMI (or Human-Machine Interface) of a process control system shows the functional components of the system and their status.
