This document is a user manual for SIMATIC FM 350-1 function module, which introduces the basic functions of FM 350-1 hardware and software, as well as the corresponding test functions. It takes 1 to 2 hours to complete this example, depending on the user's experience.
The guide introduces users to the FM 350-1 function module and walks through four steps to set up a complete functional application. It covers safety technical tips, required hardware (S7‑300 CPU, power module, encoder, front connector, wiring) and the installation of the configuration software package.
Detailed sections describe wiring the module, configuring it in STEP 7, programming basic parameters (operation mode, encoder type, input and output settings), performing diagnostics, and testing the counter using the monitor and modify variables function. This manual is written in Chinese.
