When to use: The operational technology (OT) communications network that connects programmable controllers, remote and distributed I/O, networked field instruments, and the supervisory SCADA and HMI layer in industrial, process, and water and wastewater facilities. Covers the Purdue reference model and the boundary between the OT network and the enterprise network, security zones and conduits under ISA/IEC 62443, industrial Ethernet and serial protocol selection, transmission media by segment class, managed switches and conduit enforcement devices, redundant topologies and recovery time, traffic prioritization, time synchronization, wide-area telemetry to remote sites, the device hardening, account, patch, logging, and backup baseline, and the cable, functional, and security acceptance tests that put the network into service. Applies to new networks, full replacements, and substantial expansions of an existing OT network.
− Not intended for: Commercial building automation networks and their BACnet and Modbus building field buses ([[sync/building-automation-system]]); enterprise local area networks, office structured cabling, and telecommunications rooms ([[sync/structured-cabling]], [[sync/telecommunications-rooms-and-pathways]]); the controllers on the network ([[sync/programmable-logic-controllers]]); the supervisory software and operator interface ([[sync/scada-and-hmi-systems]]); the field instruments and final control elements the network reaches ([[sync/process-instrumentation]], [[sync/flow-measurement]], [[sync/analytical-instrumentation]], [[sync/control-valves-and-actuators]]); the panels and enclosures that house network hardware ([[sync/industrial-control-panels]]); programming, configuration, and system integration ([[sync/control-systems-integration]]); cable construction and jacket ratings ([[sync/conductors-and-cables]]); raceway and pathway ([[sync/raceways-and-conduit]]); and the building grounding electrode system ([[sync/grounding-and-bonding]]).
