Table 6: Analog Input Status Readings
C1.03 Analog Input 1 Polarity (ICR, Preset: Unipolar)
Configures the type of analog input signal used, either UNIPOLAR or BIPOLAR .
C1.04 Analog Input 1 Filtering (R/W, Preset: 0)
Sets the level of digital filtering applied to the input signal. The adjustment ranges from 0 (no
filtering) to 15 (heavily filtered). Range: 0..15
C1.05 Analog Input 1 Type (ICR, Preset: Voltage)
Configures the type of analog input signal used, either VOLTAGE or CURRENT .
C1.06 Analog Input 1 Unipolar 0% Calibration (R/W, Preset: 0)
Defines the minimum signal level in UNIPOLAR mode. An input value below this level will be
ignored. Refer to Figure 24. Range: 0..4095
C1.07 Analog Input 1 Unipolar 100% Calibration (R/W, Preset: 4095)
Defines the maximum raw signal level in UNIPOLAR mode. An input value above this level will
be ignored. Refer to Figure 24. Range: 0..4095
C1.09 Analog Input 1 Bipolar 100% Calibration (R/W, Preset: 2047)
Defines the maximum raw positive and negative signal levels in BIPOLAR mode. Any input
value exceeding this level will be ignored. Refer to Figure 24. Range: 0..2047
C1.10 Analog Input 1 Bias (R/W, Preset: 0.00)
Defines the value of the target parameter when the input signal is less than or equal to the 0%
Calibration. Refer to Figure 24. Note that the formatting of this parameter will change to match
that of the target parameter. For example, if the target parameter is percent, this parameter will
be percent. If the target parameter is Seconds, this parameter will be Seconds.
C1.11 Analog Input 1 Gain (R/W, Preset: 100.00)
Defines the value of the target parameter when the input signal is greater than or equal to the
100% Calibration. Refer to Figure 24. Note that the formatting of this parameter will change to
match that of the target parameter.
