When the analog input has a thermocouple type, it can only do up to 15 channels, of which AD4 is the
ambient temperature of the thermocouple. You can do 16 channels without the thermocouple type.

R23960 starts with a zero correction value and default is 0 (Namely, size correction).
R23980 starts with a negative temperature amplification. The default is 4633 (temporarily only have
negative temperature amplification).
The 16 registers starting from R23620 are 0~10V or 0~20mA corresponding values, that is, real-time
sampled values.
2.6.5 Analog input sampling
Filtering cycles=( R23600~R23615)* PLC scanning time, if R23600=1, One PLC scan cycle sample
one time and change the 1
st
analog input value for one time. The larger R23600~R23615 value is, the result
is more stable.
R23600~R23615 is filtering cycles, default is 100 (range 2~20000), data can’t be equal to or less than 0;
D8073 is smoothing filter coefficients of all analog input, range: 0~999
