Page 6: Basic Program Examples
The analog values of each channel are transfer to digital values and stored in D8112&D8113. On the contrary process, digital value in each channel will be converted into analog value and output in system address (D8114, D8115). 6.1 Basic Program Examples Caution: WECON Technology Co., Ltd. - Page 7 6.2 Application example Since the LX3V-2TC2DAI-BD does not have offset and gain functions, if it needs for the values out of the standard specifications, Additional programming orders will be needed to multiply or divide the converted value.
- Page 8 LX3V-2TC2DAI-BD In Thermocouple input mode, LX3V-2TC2DAI-BD covert an analog value to a digital value in degrees Celsius. If in the program is Fahrenheit as a unit it needs to be converted to Celsius value. Fahrenheit and Celsius conversion formula, Fahrenheit = Celsius * 9/5 + 32, the unit is 0.1 ℃.
