The Objects
Chapter 10
10-30
Numeric Data Display
The Numeric Data Display object allows the operator to monitor PLC
variables such as temperature, level and speed.
As with other display objects, you can assign a PLC output or input
address to a Numeric Data Display Displayed Value Address. If you assign
an output address, the value stored in the PLC data table is transferred to
the terminal.
If you assign a PLC input address you will probably want to use Numeric
Data Displays with other objects. For example, you could include
Increment and Decrement buttons, or a Numeric Keypad (for Touch Screen
terminals), or a Numeric Keypad Enable button (for Keypad terminals) on
the same screen as a Numeric Data Display. If you assign the same input
address to both the Numeric Display object and numeric entry objects, you
could see the new value as you change the value in the PLC controller.
IMPORTANT: If you assign a PLC input address shared by a retentive
object, your PanelView terminal will retain the current PLC input address
value even after you’ve powered down the terminal or switched to
Configuration mode.
The Numeric Data Display object supports two types of numeric displays,
Standard and Scaled. Choose Standard to display “raw” PLC values.
Standard Numeric Data Display
The Standard Numeric Data Display has two display options, a decimal
point position and a polarity indicator (the negative sign). Several more
choices arise from these two options. The following table shows the
breakdown of formatting options, and the addressing limits for each option.
