Now, with many control systems being 30+ years old, most of these legacy systems have been placed in to end of life or retired lifecycle status. This means no further factory support is available. I caught up with Emerson’s Scott Ross about some of the choices that must be considered moving forward.
Manufacturers and producers face options whether to modernize to a newer family of distributed control systems (DCSs) and programmable logic controllers (PLCs) or move the PLC I/O and logic to a DCS, such as the DeltaV DCS. For many users with legacy PLCs and DCSs, the ongoing challenge has been to decide what I/O solution to use in the migration project.
Many users have been very creative with the use of DeltaV Electronic Marshalling – CHARMs solutions. This approach locates the I/O out in the process, provides mounting options horizontally, vertically or both, communicates with the DeltaV communication backbone via fiber or copper, and enables the removal of 30-year-old intrinsically safe (I.S.) barriers by using the I.S. Electronic Marshalling – CHARMs. These provides both signal characterization and galvanic isolation for intrinsically safe applications.
