During operation, fieldbus really demonstrates its advantages for the operator and maintenance team. Field devices provide status and diagnostics information that they group into common alarms in accordance with NAMUR recommendation NE 107. If the instrumentation indicates that maintenance is required, maintenance staff can generally start working before a fault negatively affects plant operation. Additionally, plant operators can adjust the configuration of the instruments via the fieldbus.
Advanced Diagnostics
Advanced diagnositcs brings transparency to fieldbus infrastructure allowing operators to minimize fault conditions while achieving highest plant availability. Learn more about the FieldConnex® Advanced Diagnostic Modul (ADM) and Fieldbus Diagnostic Handheld (FDH-1) that provide interpretation in plain text for many typical fault scenarios so a technician can maintain the installation even without intensive training.
The ADM continuously monitors the status of the physical layer and automatically reports discrepancies—such as ground faults or poor signal quality—to the maintenance teams at an early stage. This is especially useful if the installation is exposed to harsh ambient conditions.
Installation and maintenance professionals can check the status of the fieldbus installation anytime and anywhere using the mobile FDH-1. An integrated expert system provides easy-to-understand information on fault causes and how to correct them. The FDH-1 enables reliable fieldbus diagnostics to be performed without intensive training, making it suitable for both experienced users and beginners.
