Chapter 4 Module Configuration, Output, and Input Data
C n PW - Counter Preset Warning (Ctr[0] . PresetWarning to
Ctr[3] . PresetWarning)
This bit is set when Ctr[
n].CurrentCount has been forced by the module to the
Ctr
nPreset value. This will happen when a configuration array is accepted, which
sets the following:
• Ctr nMinCount > Ctr[n].CurrentCount
or
• Ctr nMaxCount < Ctr[n].CurrentCount.
This bit is reset by a 0 to 1 transition of the Ctr
nResetCtrPresetWarning bit in the
output array.
TIP You must manually reset CnPW, COvf, CUdf and REZ (but not IDW, RV or
IC) to enable them to be set again.
