Low risk control (parallel operation, phased migration, can be rolled back to the old system at any time) High (one-time switching, no rollback path for faults)
Low maintenance cost (module hot plugging, integrated diagnosis, fast fault location) and high (complex troubleshooting of hard wired faults, requiring point by point testing)
2. Differences from other electronic grouping schemes
Compared to competitors such as Rockwell PlantPAx electronic grouping and Siemens PCS 7 Distributed I/O, the uniqueness of the DeltaV solution lies in:
Deep integration of DeltaV ecosystem: The CHAR module is seamlessly compatible with DeltaV controllers and software (such as DeltaV Operate and DeltaV Explorer), without the need for third-party adaptation tools;
Strong adaptability of legacy system: providing dedicated migration tools for Emerson's old systems (such as RS3), which can automatically convert control logic and I/O databases, reducing manual configuration workload;
More comprehensive diagnostic functions: The CHAR module supports "channel level fault diagnosis" (such as disconnection, overcurrent, signal drift), and uploads diagnostic information in real time to the DeltaV alarm system without on-site inspection.
