According to EN 50170, Profibus is the internationally standardised bus for industry and building automation systems.

Profibus DP opens up the world of standardised network communication up to 12 Mb/s for a wide range of applications between different manufactures.


Profibus-DP with Saia PCD®

Saia PCD® controllers are available with Profibus DP master and slave connections. Version DP V0 is supported. Decentral data points

under the designation PCD3.T760 supplement the Profibus product range and enable the construction of decentralised automation solutions.

Thanks to the diverse communication properties, Saia PCD® controllers are ideal for use as communication gateways, e.g. Ethernet–
