1039 Peak1 Cfg
Peak 1 Configure
RW 16-bit
Integer
Configures operation of each peak detector.
Bit 0 “Peak1 Peak” – 0 = Capture minimum value of the input signal. 1 = Capture maximum value of the input signal.
Bit 1 “Peak1 Hold” – 0 = Monitor input. 1 = Ignore input and hold output at present value. This bit is overridden by Bit 2.
Bit 2 “Peak1 Set” – 0 = Resume normal capture of the input signal value (assuming Bit 1 is also = 0). The preset signal will be used as a starting value to compare
against further changes in the input signal level. 1 = Force output of the peak detect function to equal the signal selected by [PkDtctnPresetSel].
1040 Peak 1 Change
Peak 1 Change
RO 16-bit
Integer
Status of the peak detectors.
1041 PeakDetect1 Out
Peak Detection 1 Output
Displays the output of the peak detector, according to the operation selected by the
configuration bits, and is always displayed as a real number, regardless of the selected
signal type.
Default:
Min/Max: 0.000000
–/+2147483648.000000 RO Real
1042 PkDtct2 In Sel
Peak Detection 2 Input Select
Selects the input data source for the peak detect functions. The functions can be
configured to sample and hold either the largest (maximum) or smallest (minimum)
value of the input signal selected by this parameter.
Important: Either real or integer data sources can be selected, but integer sources will
be internally converted to real and displayed in the peak detect output as real numbers.
Default:
Min/Max: 1035
0 / 159999 RW 32-bit
Integer
1043 PkDtct2PresetSel
Peak Detection 2 Preset Select
Selects the preset data source for the peak detect functions. The output of the each peak
detect function can be forced to equal the value of the input signal selected by this
parameter by using the “Peak2 Set” bit in P1044 [Peak2 Cfg]. The same integer to real
number conversion applies to both the input and the preset signal.
Default:
Min/Max: 0
