30
In the above figure, when M0 is closed, the value -100 is transmitted to the correction register
R23960, and now you can see that the value of the actual measured temperature D20 is close to the
actual temperature which is 37.9
°
C.
2.7 Analog output
Analog output range 0~4000, precision is 12 bit. Support TO instruction or register assignment operation
directly.
Adopts TO K0 K0 D500 K8, 8 channels 0~10V or 0~20mA analog output.
Register assignment operation directly: D8050~D8057.
When the analog output is current, the bit of D8058 needs to be set:
When the default D8058.0~D8058.7=0, it means 0~20mA; when D8058.0~D8058.7=1, it means
4~20mA.
Example
：
Below shows the 0-10V voltage analog output.
At this point, use a multimeter to check the voltage of the DA0 terminal, that is, the multimeter's
red pen is connected to the DA0 terminal, and the black pen is connected to the GND terminal. The multimeter
is displaying 5V voltage value.
2.8 PID instruction
Detailed information please refer to <Mitsubishi FX3G Programming Manual>
The self-tuning method in the PID instruction has only a step response mode. The step value is S0+22.
