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.
