This BD board does not use I/O units, the converted data will be sent directly into the PLC
register. The channel’s corresponding PLC register ID is:
Channel 0CH 1CH 2CH 3CH
AD signal/Temperature
value ID1000 ID1001 ID1002 ID1003
PID output value ID1004 ID1005 ID1006 ID1007
Set the target value QD1001 QD1002 QD1003 QD1004
D/A Output Value QD1000
Kp QD1005 QD1009
Ki QD1006 QD1010
Kd QD1007 QD1011
Diff QD1008 QD1012
Dead Band -- QD1013
Start/Stop Y1000 Y1001 Y1002 Y1003
Note:
1.
Both 0CH and 1CH are PT input channels; 2CH and 3CH are AD input channels
2. Kp: proportion parameter
3. Ki: Integral parameter
4. Kd: Differential parameter
5. Diff: Control band
Control band
6. (Diff): Carry on PID control in the assigned band;
7. Start Signal (Y): Close PID control when Y is 0, open PID control when Y is 1
8. Dead Band (Dead Band): Compare the current PID output value with the preceding PID
output value. If their difference is less than the set Dead Band, the module will not use the
current
PID output value and will transfer the preceding PID output.
