SC-SERVOMOTOR: RS-485 communication documentation

We are making a description of RS-485 communication for the ELETOR SC-SERVOMOTOR controller available.

The documentation shows how operating data, user settings and diagnostic information are made available via the serial interface. Communication takes place cyclically in ASCII format, using simple JSON frames, which makes integration with master devices and modern automation systems easier.

The description covers, among other things, RS-485 communication, an additional TTL 0-5 V interface, asynchronous transmission at 19200 bps in 8N1 format, as well as the cyclical transmission of data without the master device needing to poll the controller. The document also includes a parameter map, alarm status, error codes and practical information important for integration with external systems.

The solution has been designed for easy cooperation with platforms and systems such as Raspberry Pi, Home Assistant, BMS, SCADA and dedicated user applications. The documentation also describes the differences between the RS-485 and COM TTL 0-5 V interfaces, and highlights the need to match voltage levels correctly when working with devices using 3,3 V logic.
