78 Analog I/O Modules (AD268 / DA264 / TC218)
6. Parameters PART 3 TC218
Averaging times:
(H8010 to H8017)
This parameter is for the averaging processing for the analog input data. The moving average
is calculated by the given averaging times parameter.
For example, if the averaging times parameter is 100, the average value of latest 100 times
conversion is output as the A/D conversion data.
This function is effective to reduce the fluctuation caused by noise.
The available setting range is as follows.
Input type A v eraging times
Upper limit 127
Default value 1All types Lower lim it 1
Input type setting:
(H8018 to H801F)
This parameter is used to select the input type. This parameter also has a function to skip the
A/D conversion for unused channels. By using the channel skip function, the conversion cycle
time can be reduced.
The available setting range is as follows.
Input type Setting v alue
Type K thermocouple 0
Type J thermocouple 1
Type E thermocouple 2
±100mV 5
The default setting value (factory setting) is 5 (±100mV).
