| Abstract: | A method for controlling Siemens MM440 inverters through a Web browser was imple- mented by combining Internet and embedded technologies. The hardware circuitry adopts the LM3S8962 microcontroller as well as peripheral DAC and on/off control modules. The software design is composed of the following parts： migrating and configuring the μCO/S - Ⅱ real time operating system and the embedded TCP/IP; designing the HTTP server, DAC module and on/ off control programs. Inverter operations such as start, stop and frequency setting can be performed on the user side simply through a browser. |
