Display Formatting

When fewer digits than the maximum are to be displayed, the left portion

of the display must be filled with either blank spaces or zeroes. You can

choose either spaces or zeroes by choosing Fill Left With.

If the value cannot be displayed within the number of digits specified for

the object, a string of asterisks (*) is displayed instead.

Displays with Decimal Point

The position of the decimal point can be fixed or PLC controlled.

To create a fixed decimal position, you select the number of digits that will

be displayed to the right of the decimal point. The number can be 1 to 7

(the default is 1).

To create a PLC controlled decimal point, you must assign a Decimal Point

Position Address, a PLC input or output address. This three-bit binary code

indicates the number of digits to the right of the decimal. For example, a

value of zero (000 binary) means that there will be no digits displayed after

the decimal point (and the decimal itself will not be displayed); a value of

three (011 binary) means there will be three digits to the right of the

decimal point; a value of seven (111 binary) means that seven digits will be

displayed to the right of the decimal point. The remaining bits in the word

address can be assigned to other functions.

Use a PLC input address if you want to control the decimal position from

the terminal using other input objects. If you want the PLC controller to

dynamically change the decimal position, assign a PLC output address for

the decimal point. No PLC address is needed if the decimal position is

fixed.

With a decimal point but no polarity bit, this object can display 2 to 8

digits (the default is 6). The maximum PLC value depends upon the data

type and number of bits assigned to the Displayed Value Address.
