Chapter 6 Temperature Measurement Module AS04/06RTD
6- 15
6.2.6 Functions
Use the HWCONFIG utility software built into ISPSoft to set modes of operation and parameters.
Analog input
Item Function Description
1
Enable/Disable a
Channel
1. Enable or disable a channel.
2. If a channel is disabled, the total conversion time decreases.
2 Unit of Measurement
Select the unit of measurement: Fahrenheit or Celsius.
3 Calibration Calibrate a linear curve.
4 Average Conversion values are averaged and filtered.
5
Disconnection
Detection
If the channel is open, the module can detect when it is disconnected. If
the input is open-circuited, the module produces an alarm or a warning.
6
Channel Detection
and Alarm
If an input signal exceeds the range of inputs that the hardware can
receive, the module produces an alarm or a warning. You can disable
this function.
7
Limit Detections for
Channels
Save the maximum/minimum values for channels.
8
Records for
Channels
Save the analog curves for channels.
9 PID Algorithm PID control modes
1. Enable/Disable a Channel
An analog signal is converted into a digital signal at a rate of 200 ms per channel. If a channel is not used,
you can disable it to decrease the total conversion time.
2. Unit of Measurement
Select the unit of measurement, Fahrenheit or Celsius, according to your needs.
3. Calibration
To make a curve meet specific needs, calibrate the curve by changing the offset and the gain. The
calibration range depends on the range of inputs that the hardware can receive. The formula is:
