Kaidian KDN-K306 PLC PID Function Block Manual
The document provides detailed instructions for using the PID function block in Kaidian KDN‑306 PLCs. It describes the available input and output variables, the structure of the PID block, and the logic for manual and automatic control modes.
Key sections include a list of 12 input variables and 2 output variables, the formulas for normalization and output scaling, and a practical example that controls a heater using a 4‑20 mA signal. The example shows how to map PLC internal values (1000‑5000) to an analog voltage range of 1‑5 V. This manual is written in Chinese.
Covers: PID Function Block Overview · Input Variables · Output Variables · PID Program Description · Manual Mode Operation · Automatic Mode Operation

Questions answered in KDN-K3 manuals
How does manual mode affect the PID output?
In manual mode AUTO is set to 0, and the input variable XO is passed directly to XOUT (range 0‑1); other inputs are ignored.
What is the formula used for automatic mode normalization?
When AUTO is 1, the difference between SP and PV is normalized using the linear formula Y = K·X + B before PID calculation.
