This manual introduces the SIMATIC PID Self‑Tuner V5, describing how to install it on an S7‑300/400 station, configure hardware modules, and start the software. It covers the required hardware, STEP 7 setup, and the workflow for creating and downloading projects.
The document then explains the application areas, function block descriptions, several example projects (plastic industry, furnace control, simple temperature loops), and provides technical specifications such as runtime values and memory allocation for the TUN_EC and TUN_ES function blocks. This manual is written in Chinese.

You need an S7‑300/400 station with a power supply, CPU, analog input module, digital output module, and STEP 7 (≥ V3.2) installed on the programming device.
First let the process reach a stable temperature, set ADAPT1ST to TRUE, input a positive set‑point step larger than MIN_STEP, and set the controller to automatic mode (MAN_ON = FALSE).
The process must have a stable time‑delay transient response, not too long delay, a sufficiently linear response, minimal disturbance for temperature processes, and a high signal‑to‑noise ratio.
