1. Modules information
1. Basic Characteristics
XC series PLCs not only have strong functions of logic operation, data operation, high speed processing
etc. but also functions of A/D, D/A conversion, PID adjustment. With the expansions of analog input module,
analog output module, temperature control module etc, XC series PLCs are widely used in the control
system of temperature, flow, liquid level, pressure.

5. Notes
 Please confirm the specifications, choose the right module
 When wiring the module, please prevent the scraps falling into the modules
 Before connecting, please confirm again the module specifications and connected device
 When connecting, please check if the connection is firm, cable broken will cause data incorrect, short
circuit and other errors! Installation, layout should only be carried on after cutting the power.

2. PID Function
1. Brief introduction of PID function
Among XC series PLC special modules, digital input module (A/D module) and temperature control
module both have PID control function which is widely used. There are only four parameters (Kp, Ki, Kd and
Diff) should be set.
2. PID Parameters
Kp — P is proportion parameter, to control the offset of the system once it happens.
Ki — I is integral parameter, to eliminate the static error, improve the no error degree of the system.
Kd — D is differential parameter, to control the signal changing trend, decrease the system vibration.
Diff — Control range, to do PID control in the defined range.
Death — Death area, compare the current PID output to the former one, if the difference is less than the death
area value, the module will abandon the current PID value, send the last value to the PLC.
3. Control characteristics
The range of PID adjustment is, when the testing value is low than QD-Diff, controller outputs with the
full scale; when the testing value is larger than QD+Diff, the controller stops outputting; in the range of
QD-Diff to QD+Diff, carry on PID adjustment.
The control curve of PID:
Each parameter’s reference value: Kp=20~100；Ki=5~20；Kd=200~700；DIFF=100~200.
