IACS (industrial automation and control system)
The IEC 62443 umbrella term for the control systems, their networks, and the associated systems that run industrial processes, from PLCs and SCADA to safety instrumented systems.
Why it matters for wireless
IEC 62443's scope covers industrial control systems and their associated communications networks, so a wireless network that carries control traffic is part of the IACS, not only an IT wireless asset.
IEC 62443 uses IACS to cover control systems in manufacturing and processing plants, building controls, utilities, pipelines, and transportation networks. Its scope includes industrial control systems and their associated communications networks, such as PLCs, SCADA, and safety instrumented system functions, plus associated systems at level 3 or below.
ISA describes the 62443 series as requirements for electronically secure industrial automation and control systems. Vendor design guides use the same term for the equipment in the plant’s Industrial Zone.
