输入校准
每个输入通道在工厂进行校准。在校准过程中，units must also be specified to ensure proper scaling and corrections for calibration, cold junction compensation, and nonlinearity correction.
Add FC 215 and 216 to the controller to configure the ASI module. Set FC 217 in the controller to calibrate the ASI module or
to set the user gain and offset values. Refer to the Composer
Function Code Application Manual for more information.
Automatic Adjustments and Corrections
Input processing, calibration, point value calculations, lead
wire resistance adjustment, cold junction compensation, gain
and offset adjustment, and engineering unit conversions are all
automatically performed by the ASI module.
Input Processing
Each A/D converter samples the input signal continuously
without need for a start convert command. The A/D output
register is updated at a rate determined by the internal filter
and can be ready at any time. The ASI module scans all A/D
converter output registers at a rate of about 180 milliseconds
including calibration and open circuit tests.
In addition to the input channels, the built-in cold junction reference is read during normal input scanning.
Automatic Adjustments and Corrections
WBPEEUI240774A0 2 - 7
Point Value Calculation
The ASI module maintains a set of adjustment values for each
input channel. These values correct for offset and gain errors
in the input channel. The raw analog-to-digital converter count
value is converted to an actual input signal value using the calibration data.
For thermocouple inputs, an adjustment is made for the cold
junction temperature of the thermocouple. An additional,
user-specified adjustment is then applied, if one has been
defined with FC 217. The final corrected input reading is then
converted to engineering units using either thermocouple or
RTD conversion tables, or the engineering unit zero and span
values specified for the input.
The following sections describe the various types of input value
adjustments.
Input Calibration
Each input channel is calibrated at the factory. During the calibration procedure,
