3．3．9 Analog Amplifier（AMPT）
Symbol in APB
Pin
Reset R

Description
A signal at input R resets the analog amplifier.
Q
P
AMPT
Input AIX
Analog input.
Output Q
Input value is output after calculation.
Output P
Output the running value of the block to the Register DW.
Parameter Setting:
A：Gain value; Range of values: -10000~10000
B：Offset value; Range of values: -20000~20000
Functional Description:
The input value is multiplied by the value of the A (gain) parameter, and then parameter B (offset) is
added to the product: (Ax * gain) + offset = actual value Alx.
The actual value Alx is output at Q.
3．3．10 Analog Watchdog（AWDT）

R
Q
P
Description
Analog input.
Input EN
A positive edge (0 to 1 transition) at input En saves the analog
value (V) at input AIX to memory and starts monitoring the
range of analog values.
Reset R
A signal at input R resets the analog watchdog.
Output Q
Q is set or reset, depending on the stored analog value and the
offset.
Output P
Output the running value of the block to the Register DW.
Parameter Setting:
A: Gain value; Range of values: -10000~10000
B: Offset value; Range of values: -20000~20000
△ 1: Difference value above V; range of values: 0.00~20000.00
△ 2: Difference value below V; range of values: 0.00~20000.00
