AO Faceplate: Main Frame
Refer to the following table for descriptions of the fields.

Area | Description |
1 | Process Variable (PV) high value in Engineering Units. Question marks display if invalid or no scaling is configured. To determine why question marks display, view the scaling parameters on the Details frame. |
2 | PV Fill Level: Animated fill level. Displays the PV engineering value in relation to its range. Will not display if invalid or no scaling is configured. |
3 | Process Variable (PV) low value in Engineering Units. Question marks display if invalid or no scaling is configured. To determine why question marks display, view the scaling parameters on the Details frame. |
4 | Process Variable (PV) value in Engineering Units. The displayed value is the current PV value. PV is converted into RAW based on the configured scaling. If no scaling is configured then RAW is set equal to PV. |
5 | Engineering Units. Examples of engineering units are PSI, inches, volts, pounds per hour, standard cubic feet. |
6 | Overrides the RAW value with a user specified value. Display options include: Active or Inactive. With Active, the RAW value is currently forced. With Inactive, the Forcing is inactive so the RAW value is based on PV and the configured scaling. Forcing can be set to Active or Inactive on the Details frame. |
7 | Exit button. Click to close the faceplate. |
