2) Each channel’s working mode is assigned by the four bits of the corresponding register, each
bits definition is shown below:
Register FD8306:
1. Usage of four parameters: Proportion parameter (Kp), integral parameter (Ki), differential
parameter (Kd), control proportion band (Diff).
2.
Parameter P is proportion parameter, mainly reflect system’s wrap, when system wrap
appears, carry on control immediately to decrease the wrap.
3. Parameter I is integral parameter, mainly used to remove net difference, improve the systems
no-difference degree
4. Parameter D is differential parameter; mainly used to control the
signal’s change trend,
decrease system’s shake.
5. Temperature control proportion band means: in the assigned band, carry on PID control,
beyond the band, do not carry on PID control.

2-5 Working Mode settings
1) Expansion’s input has voltage 0/5V and 0/10V. These
two modes and filter form to select. Set via special
FLASH data register FD8306 in PLC.
Refer to the graph (right) each register set the 4
channels’ modes, each register has 16 bits. From low bit
to high bit, each 4 bits set one channel mode.
