5、Items to note when using
Please confirm the specification, choose suitable module
When carry on processing the screws or layout project, please protect the scraps falling into the modules
Before connecting, please confirm again module’s specification and connected device
When connecting, please check if the connection is fastness, cable breaking off will cause data incorrect,
short circuit and other fault! Installation, layout should only be carried after cutting all power.
Ⅱ、PID Function
1、Brief introduction of PID function
Among XC series PLC special modules, digital input module (A/D module) and temperature control
modules both have PID control function. It is widely used and flexible. When using, only four parameters
(Kp、 Ki、 Kd and Diff) should be set.
2、Parameter’s usage
Usage of four parameters: Proportion parameter（Kp）、Integral parameter（Ki）、Differential
parameter（Kd）、Control proportion band（Diff）
Kp—parameter P is proportion parameter, mainly reflect system’s wrap. When wrap occurs, carry on control to
decrease this wrap.
Ki—parameter I is integral parameter, mainly used to eliminate whisht difference, improving system’s no
difference degree.
Kd-- parameter D is differential parameter, mainly used to control signal’s changing trend, decrease system’s
shake.
Diff—Control bound means in the assigned bound, carry on PID control, out the bound, do not carry on PID
control.
3、 Contr ol characteris tic
The bound of PID adjustment is, when the testing value is low than QD-Diff, controller output with the
full scale; when the testing value is larger than QD+Diff, the controller stop output; in the bound of（QD-
Diff，QD+Diff）, carry on PID adjustment.
The control curve of PID is the following:
Each parameter’s reference value: Kp=20~100；Ki=5~20；Kd=200~700；DIFF=100~200.

Description：
Start signal（Y）：when Y is 0, close PID control, when be 1 , start PID control
Parameter P：Proportion parameter, mainly reflex system’s difference, carry on control as soon 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.

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 channel’s working mode is assigned by correspond register’s 4 bits. Each bit’s definition is showed in the
following table:
The following, we take module 1 as example to show how to set:
Register FD8250：
Register FD8251 low byte：

Take 1# expansion as example ：
FD8250 H O O O O
0CH
1CH
2CH
3CH
FD8251 H O O O O
4CH
5CH
E,g. ： 1 ） If set working mode 0~20mA 、 4~20mA 、 0~10V 、 0~5V of module 1’s channel 3 、 channel
2、channel 1、channel 0, filters are all 1/2 filter, value in FD8250 is 2301H
4．Exterior connection
When carry on exterior connection, please note the following two items:
When connect＋24V power outside, please choose 24V power on PLC main unit to avoid interfere.
To avoid interfere, please use shield cable and single point grounding with the shield layer.
Module’s 0~20mA or 4~20mA output need 24V power from outside, according to the analog output
register QD’s value, the module adjusts the loop circuit’s current, but the module itself doesn’t produce
current.
5．Analog digital convert chart
The relationship between input analog and converted digital is showed in the following chart:
0~5V analog input 0~10V analog input
0~20mA analog input 4~20mA analog input
The relationship between output digital and its correspond analog data is showed in the following chart:
0~5V analog output 0~10V analog output
0~20mA analog output 4~20mA analog output
When input data exceed K4095, D/A converted output analog data keep 5V、10V or 20mA.
6．Programming
E.g.1）Real time read 4 channels data, write 2 channels data (take expansion 1 as example)
