Develop network segmentation and addressing connects with model systems, interfaces and traceability. Connect identity, protocol behavior, staged cutover and rollback evidence.
Use network and computing administration tools connects with develop network segmentation and addressing. Connect tool capabilities to design, analysis and controlled records without inferring every named product was used.
Controls ownership connected PLC, HMI, VFD, remote-I/O and SCADA requirements with process behavior. OT work included a dedicated fiber backbone, managed switching, segmentation, redundant paths, UPS support, network drawings, device configuration and cutover validation. Instrumentation and alarm behavior were coordinated with operating and maintenance response.
