The Great I/O Migration... Long-Term Benefits
ed configuration, status display, and diagnostics with NovaTech’s D/3 DCS to facilitate greater automation with better diagnos- tics, troubleshooting, and asset management capability. With this combination, operators can remotely drill down to the con- troller or I/O card without hav- ing to go into the field. First introduced in 2006,
NovaTech continues to upgrade the 8000 series, including a re- design for RoHS compliance and product enhancements, including 16 channel HART analog input, 32-point FTA, and new EBIM (Ethernet Bridge Interface Mod- ule) and EBIM carrier compo- nents. To increase reliability, redun-
dancy is built into the I/O system design. The 8000 Series features dual redundant Ethernet commu- nications and an optional 1:6 mod- ule redundancy scheme that backs up individual I/O modules for increased reliability. In the event of an issue or anomaly, the system can switch to a backup module on the carrier. The EBIMs also provide dual redundant com- munications between the PCM and 8000 I/O modules for high system availability.
Pre-Wired Systems There are advantages to
having the complete system assembled, wired, and tested in a cabinet or on a mounting plate before it is shipped to speed up the installation. Depending on the size of the
existing cabinet (in a retrofit) or the available footprint for a new cabinet, the I/O system compo- nents can be mounted and con- nected in multiple configurations on the DIN rail. EBIMs in their carrier are connected to I/O car- riers directly or through cables, in horizontal and/or vertical con- figurations to a maximum rail- bus length of 21 feet. “We do similar cabinet
designs each time, but there is always something different to consider at every site, in every cabinet, that is unique. The flex- ibility in connecting and mount- ing the components allows us to accommodate various size cabi- nets or small footprints and a pre-assembled, pre-wired cabinet can be installed quickly during a planned shutdown,” says Davis. NovaTech can custom de-
sign and install components on mounting panels if a cabinet is not required. “Usually, the shutdown
needs to be as short as possible, so having everything ready and test- ed and the software configura- tions completed as much as possi- ble ahead of time is a major con- tributor to a successful migra- tion,” says Davis.
“Running to fail is not a long-term solution,” says Davis. “Recycling and refurbishing old parts or turning to eBay is not a sustainable strategy.”
For managers who want to understand their obsolescence risk and prioritize modernization needs and goals, a life cycle analysis is recommended to assess the equipment, spare parts, and software inventory. Because no two control sys- tems are alike, each upgrade also
presents unique circumstances that prevent utilizing a cookie- cutter approach in the prelimi- nary engineering and quoting process. For this reason, partner- ing with an automation expert is highly advised.
“Processing companies need to perform a thorough assess- ment of their control system, with an automation expert that can make recommendations on which equipment should be upgraded first.
Having a concise plan and roll-out schedule is essential to a successful modernization effort

because it is a big project,” says Davis. Due to the fact that in
migrating I/O there are a variety of different approaches and even custom solutions available, de- pending on the type of I/O that is being upgraded, it’s important to work with a partner and develop an effective plan to minimize downtime and maximize the lifespan of the system.
