Packed with complete DCS functionality,
the LCBs/LCUs are programmed with
function blocks designed specifically for
process control. Similar to preparing a
flow sheet, function blocks are pasted
and connections made using a graphic
interface. A wide array of control
methods, from basic PID control to
cascade and feed-forward control, are
possible.
