Many control schemes call for redundancy, but this traditionally requires intermediary equipment to integrate final control devices like variable frequency drives (VFDs). To simplify this common architecture, Emerson announces a new PROFINET System Redundancy (PNSR) communications card that plugs into PACMotion VFDs, simplifying high availability communications between VFDs and Emerson’s PACSystems RX3i programmable logic controllers (PLCs) and edge controllers.
PACMotion VFDs already offer plug-and-play startup, auto-tuning, and simplified programming via configuration tools incorporated directly within PAC Machine Edition software. The addition of the optional PNSR communications card enables direct connection and control of PACMotion VFDs in hot standby PACSystems redundant architectures, improving the availability of the VFD in the event of a single controller or communications link loss. The new communications card provides high availability control functionality, maximized uptime and improved availability.
The VFD PNSR allows users to simplify and save up to 15% on integration products and efforts and is compatible with all PACSystems PLCs and edge controllers that support high availability. This communications card, once installed in the VFD option card slot, ensures an easy and seamless direct connection to VFDs without requiring any other intermediary controllers or external components.
Emerson’s PNSR high availability communications card is an advanced addition to the PACMotion VFD and PACSystems automation portfolios — providing automation engineers, end users, OEMs and systems integrators in all industrial market segments with the cost-effective reliability they need to prevent unplanned downtime.
