SPI 3 - Serial PROFIBUS Interface

Connecting Serial Devices to PROFIBUS Networks

By using the SPI 3, devices with serial interface are integrated in PROFIBUS as DP slaves. Depending on the application, various protocols and physical interfaces are available. In decentralized PROFIBUS installations, the SPI 3 replaces the serial interface inside the PLC. The SPI 3 is configured via the respective PROFIBUS DP master by means of the SPI 3 GSE file. The PROFIBUS IO range can be flexibly configured. The SPI 3 is suitable for simple applications, such as connecting text displays or barcode scanners, as well as for more complex applications such as the integration of identification systems, scales, controllers and laboratory equipment.
