as difference occurs to improve the system’s no difference degree.
Parameter I
:
Integral parameter. Mainly used to remove whisht, improve the system’s no
difference degree.
Parameter D
:
Differential parameter, mainly used to control signal’s changing trend,minish
system’s shake.
Control bound Diff
:
In the assigned bound, carry on PID control. Beyond the bound, no PID
control.
Dead area Death
:
When the current PID control value compares with the preceding PID control
value. If the difference between them is less than the set dead bound’s value,
the module will abnegate the current PID control value, send the preceding
PID control value to the PLC main unit.
Each parameter’s reference value

Kp=20~100

Ki=5~20

Kd=200~700

Expansion’s input/output mode can be set via special FLASH data register FD
inside PLC.

Note
:
As showed in the preceding table,
each register set 4 channels’ mode, each
register has 16 bits. From low bit to high
bit, every 4 bits separately set 4 channels’
mode.
