Meters

Meters provide a graphical and a numeric representation of instrument readings. The graphical representation allows you to visually compare the PV with reference values such as alarm limits and/or user-configured reference values (e.g., the “tracker” or optimal range). Many of the meters have variations that allow them to also be used to represent a controller. These variations include additional elements such as output (OP) and feedback indicator (FB).

You can insert multiple instances of a meter in duplicate or triplicate by using the Meter_Multiple.xml Composite Genie.

Meters are associated with equipment, and require the following items to be defined:

Item Name	Description
FB	Feedback Indicator
OP	Output
ORDsp	Optimal Range Display
ORLow	Optimal Range (OR) Low
ORHigh	Optimal Range (OR) High
PR	Practical Range specific to Deviation meters
PRLow	Practical Range (PR) Low
PRHigh	Practical Range (PR) High
PV	Process Variable
PVTarget	Process Variable specific to Target meters
PVTrack	Process ValueTracker
SP	Setpoint
TrackDsp	Controls whether or not a tracker is displayed
