Explanation:
PanelView
1
Starts/stops, auto/manual operations,
setpoints, outputs, alarms
Used as an operator window to enter commands that make process adjustments such
as starts/stops and loop changes. Can also be used for alarming operations. Can
communicate with a single PLC5 processor on a remote I/O link. Has a fixed number
of devices and amount of data that it can handle. Has builtin error checking. Is an
industrialhardened CRT with pushbuttons, solid state memory and processor, and no
moving parts (i.e., disk drive).
Utilizes pass through, which is the ability to download/upload via DH+/remote I/O links.
ControlView
1
Store, display, and manipulate data
on process performance (i.e., trends,
process graphics, formulas, reports,
and journals)
Used as an operator window that communicates with a PLC5 processor on Data
Highway Plus (DH+) link. Designed for use as an information link. Can communicate
to multiple PLC processors. ControlView is a software package that runs on an IBMr
DOSbased personal computer.
