Be sure to read and observe the following instructions! The device has been designed in accordance with the state of the art The Stratos PROFIBUS 2221 X Oxy may be operated in accordance and complying with the applicable safety regulations.
PROFIBUS technology General PROFIBUS is a digital communication system that connects different - devices installed in hazardous locations are configured and main- field devices over a common cable and integrates them into a control tained from the control station system. In the long term, PROFIBUS will replace the 4-20 mA tech- PROFIBUS is the leading open fieldbus system in Europe.
Definitions for PROFIBUS-PA The bus protocol defines type and speed of the data exchange - Acyclic services are used for device configuration, maintenance between master and slave devices and determines the transmission and diagnostics during operation. protocol of the respective PROFIBUS system. The device profile defines the device class and typical functionalities PROFIBUS-PA permits cyclic and acyclic services.
