The Masoneilan SVI (Smart Valve Interface) from Dresser is a `smart’ positioner and PID loop controller in one instrument, for use with any control valve. It now comes with the latest edition of valvue software, which offers three new facilities.
A multidrop facility permits communication with multiple SVI units connected to the I/O card of a DCS. You can add a multiplexer to the circuit allowing communication with, and monitoring of, up to 256 units. And an Asset Management Interface permits communication with SVI via the main DCS.
