  • Fieldbus Part 2
    facility, there was some concern about how to handle the many RTD inputs with a bus system. Certainly, a Foundation fieldbus transmitter for each input would be unwieldy from a construction standpoint, not to mention the cost. Fortunately, 848T allows up to eight inputs per instrument, which reduces

    during fermentation skid factory acceptance testing needed to be resolved on-site. Although there were a few issues with Foundation fieldbus devices, this fieldbus was found to provide a solid communications platform with sophisticated interaction between the DeltaV process control system
  • The Ups and Downs of Taking the Bus
    By Gary Forrest, PhD, Wyeth Research For the Foundation fieldbus devices, a single wire entered the cabinet for connection to a Relcom fieldbus connector block. Each of the Foundation fieldbus devices was then wired to the central block. Figure 2. Fermenter control cabinet with fieldbus connectors
