Understanding Profibus: A Communication Backbone for Industrial Automation

Profibus (Process Field Bus) is a digital, serial communication protocol standardized IEC 61158 andIEC 61784. It enables various devices - sensors, actuators, controllers, controllers, controlls, and I / O modules - to exchange data determinalisticaly over a single shielded twisted- pair cable or fiber- optic link.

Deterministic Real- Time Communication

In a power plant, control loops for maximum point point tracking (MPPT), grid syncization, and frequency regulation require bounded response times. Profibus DP offers cycle times as low as 1 ms for a 32- device network, witch developed latency independent of bus load.
