Part III FP Instructions
Time charts for the filter when the value assigned to s2_InputMask is 1 (16#0001), i.e. bit 0
will be filtered, the other bits will not be filtered, and the value assigned to s3_FilterTime is
500ms.

Data is initialized when the system

The instruction does not operate
while the trigger is OFF.

Variable Data type Function
s1_InputData Input data whose bits will be filtered according to the
input mask
s2_InputMask Input mask which specifies which bits will be filtered
s3_FilterTime Specifies the minimum off- and on-time in ms
d_OutputData
ANY16
Filtered data
Pre-
cautions
during
program-
ming
When the system detects a trigger's rising edge, all the bits of the input specified by s1_InputData
are output directly in d_OutputData and the effects of bounce are not prevented. A scan time error
may occur during filter processing, for a maximum of 1 scan.
