Division Block
The function block is used to divide inputs A and B hence produce the quotient Q and
remainder R.

Series Controller
1 ) Allocate the input pin to be used for the function block.
2 ) Press the “OK” key with the cursor in the function block. The function block edit screen is
displayed as shown.
3 ) Press the “OK” Key and enter the function block settings using the “ and ” keys. The
Division operation Q=A/B must be specified.
4 ) Using the “ and ” keys highlight Constant A and press the “OK” key to enter either a
Directset, Analog In or FB Value.
5 ) Repeat step 4 for Constant B and return to the FBd using the “ESC” key.

Description
I
Input pin for division function block
FB
This function block operates the expression Q=A
/
B, R=A%B
The value of Q, R, A and B is in the range: -32768 to 32767
a) A,B
- Constant value (Setting range:-32768 to 32767
- Analog value
- FB value
Output
1) Word Output
When the input pin is ON, Q=A
/
B, R=A%B and the word output will be
given the result. When the input pin is OFF the expression is not
executed and the Q and R values will retain the last result.
2) Bit Output
- Input value (B) = 0: Output pin is turned ON and the quotient Q and
R will reset to 0.
- Quotient (Q) > 32767: Output pin is turned ON and the quotient Q
will be set to 32767.
