REM
This function block returns the modulo division result of two LREAL inputs. It is useful for determining the
position within a MachineCycle.
Parameters
* Parameter Data
Type Description
VAR_INPUT Default
B EN BOOL
This function will continue to calculate the remainder
while EN his held high.
FALSE
V Numerator LREAL
The numerator for division, such as the free running
motor position, which may be outside a desired
range of values, such as 0 to 360.0
LREAL#0.0
V Denominator LREAL
The denominator for division, which is the desired
max value for the Numerator input, such as 360.0
LREAL#0.0
VAR_OUTPUT
B ENO BOOL
This output will be high if EN is high and thisfunction is able to
calculate the remainder with no errors.
V REM BOOL This output contains the calculated remainder
Error Description
This is a function, not a function block and only provides one output. If ENO is not high when EN is high, this
function cannot calculate the remainder. Verify that the Denominator is not zero.
