4.5 Monitoring the Basic and Advanced Displays

This section describes the information shown on the operator screens of the Advanced and Basic
Displays.

4.5.1 Basic Display

Figure 19 illustrates the Basic Display format with Process Variable (PV).

The PV value is user-configurable. This field has 7 characters. The maximum allowable
numeric value is 9999999 or -999999. If fractional decimals are configured, the fractional
positions will be dropped, as required. If the PV value exceeds the above limits, it is divided
by 1000 and "K" is appended to the result, allowing a maximum value with multiplier of
999999K or -99999K.

Process Variable Tag is user-configurable from a HART Host. This field has 14 characters.

Engineering Units. This field is user-configurable. This field has 8 characters.

4.5.2 Advanced Displays

As shown in Figure 20 , the Advanced Display provides three formats. Table 18 lists and describes
the fields in each of the three Advanced Display formats. Essentially, all three formats provide the
same information, but with the following differences:

Bar Graph. User Configurable 126 segment Bar Graph with range settings. The Bar Graph
displays the current value of the configured PV.

PV Trend. User-configurable display period from one hour to 24 hours. The chart displays
minimum, maximum, and average of the configured PV over the selected trend period.
