Executive Summary

In these days due to the information technology there are many ways to control a remote servomotor. In the paper it is shown a simple and reliable way to handle the control and monitoring of a remote stepper motor using a Local Area Network (LAN). The hardware uses a common PIC microcontroller and a stand-alone Ethernet controller. The main program located in the flash program memory solves the following tasks: read packs through SPI (Serial Peripheral Interface) from the Ethernet controller's buffer and decode them, encapsulate data to be sent with the Ethernet controller, control the on - off state of the transistors from the static converter and receive feedback directly from the optical sensor to monitor the actual position of the shaft.
