PLC Controlled allows the PLC controller to set the number of digits

to be displayed after the decimal point.

If you choose the PLC controlled decimal point, 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.

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.
