AF4 Division Function
An AF4 division function operates on two 6-digit BCD numbers and presents
the results in a 12-digit BCD number.
(+xxx xxx.) : (+xxx xxx.) = +xxx xxx.xxx xxx
How to Enter an AF4 Division Function
To program an AF4 division function, perform the following steps:
1. Press [SHIFT][EAF] or [SHIFT][SCT] on the keyboard of your industrial
terminal. Figure 3.1 appears on the CRT.
2. Enter 04, the function number for AF4 division.
This entry identifies that the function entered is to perform an AF4 division and
that the processor use the data table format shown in Figure 3.14 when
executed. Operands 1 and 2 represent two 6-digit numbers whose quotient you
wish to find. The six digits of operand 1 are represented in BCD by groups of
bits labeled digit 1 through 6. Digit 1 and 6 are the most significant and least
significant digits respectively. Operand 2 and the 12 digits of the result are
labeled similarly.
