Setup of the Division Function Block directly from the
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 "

Input pin for division function block
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
FB
a) A,B
- Constant value (Setting range:-32768 to 32767
- Analog value

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.
