6. Channel Detection
If an input signal exceeds the allowable range of inputs that the hardware can receive, an error message
appears and the Error LED blinks. You can disable this function so that the module does not produce an
alarm or warning and the Error LED also does not blink when the input signal exceeds the input range.
7. Limit Detections for Channels
This function saves the maximum and minimum values for channels so that you can determine the peak to
peak values.
8. Records for channels
Record the input values of the cyclic sampling for each channel. For AS04TC-A, the system saves up to
500 data points and the recording time is 10 ms. For example, if the conversion time is 2 ms and 4
channels are open, the recording time is 8 ms x 500 data points = 4 seconds in total. And the system
saves up to 100 data points for AS08TC-A and the recording time is 100 ms. The following uses
AS04TC-A as an example to demonstrate.

9. PID control
PID algorithm is available for every channel. With its auto tuning function, parameters such as Kp, Ki, Kd
and more can be calculated and therefore temperature control can be achieved. You can also use
DMPID instruction to calculate relative parameters by entering the parameters in the endpoints of the
corresponding instruction image and then you can then obtain the output values from the output
endpoints. Note: DMPID instruction is available for AS04TC-A (V1.04 or later), AS08TC-A (V1.00 or
later), AS Series PLC (V1.06 or later) and AS-SCM (V2.04 or later).
