PLC Controlled—Allows the PLC controller to set the number of

digits to be displayed after the decimal point.

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.

If you choose the PLC controlled decimal point, you will have to

choose Address in the Object menu to assign a PLC input or output

address as a Decimal Point Position Address. This three-bit binary

code indicates the number of digits to the right of the decimal. For

further details, see the section on Address that follows this section,

Format.

Decimal Key Controlled—Allows the operator to enter the

number and decimal point. The terminal interprets the decimal

point position in the window and sets the Decimal Point Position

Address to that value.

To send a decimal point value to the PLC controller, define a

Decimal Point Position Address. In this case, only a PLC input can

be used. The three-bit value stored at this address determines the

number of digits to the right of the decimal point. The relationship

between the number and decimal point is implied; the number sent

to the PLC controller does not contain a decimal point.
