Description
23314
TheFB is used to configure and to operate an input channel or a pair of input channels to detect and
count pulses.
In the operating modes IN_PHASE_CSI and IN_PHASE_CSO (to be set at the eMode function block
input), a phase measurement is carried out on one input channel pair. The input channel pair is
defined by indicating the channel with the even number of the input channel pair (channel A) at the
input uiChannel.
In the other operating modes, a signal evaluation is carried out at the input channel defined at the
uiChannel input.
