Data entry screens allow an operator to directly enter values into SLC or

PLC registers. Data entry screens can also contain a data display field.

This is how a data entry screen may appear:

Temp =150 Deg. C

Data Display Field

Data Entry Field

(Must be last on screen)

To construct data entry screens, you need to specify:

• The type of screen as data entry

• Any additional text information that you want to display

• The type of data stored in the PLC or SLC register

• The register to access (address), and if used, a display register

• Any data format and display information

• The display position for the entry field

Data entered in standard engineering units such as gallons, pounds, feet, etc.

can be scaled to machine control values. Data is scaled by setting up a

proportion between the DTAM data entry limits and the controller register

data limits. Refer to the description of scaling in Chapter 3.

Note: The 32 bit BCD data format cannot be scaled.
