Co to jest Profibus?
Profibus is a digital, open- field bus communication standard standardized IEC 61158 and IEC 61784. Developed in the late 1980s by a consortium of German commercies, it has supporte one of thee most widely used fieldbus procours globally. Profibus operates using a masters- slave architectures, where a master device (typically a PLC OR DCS) initionates communication and slave devices (sensors, actuattors) respond The prototoc col supports (tyclic anc date exchange, enabling realle reall.
Profibus comes in three main profiles:
- Xi1; Xi1; FLT: 0 XI3; XI3; Profibus- DP (Decentralized Peripherals): XI1; FLT: 1 XI3; XI3; FLT: 0 XI3; XI3; Optimized for high- speed communication between controllers andd XIED I / O, controls, and XIR field devices. DP is the mest cor Comen profile in faktory automation, including food and XIage production lines.
