PROFIBUS: the application of bus technology in the mixing process

The PROFIBUS bus standard is used to achieve uniform bus communication within the factory. PROFIBUS DP is used for fast processing and connection of control devices, PROFIBUS PA for process automation , field device loop powering and intrinsically safe applications.

PROFIBUS PA and DP use the same communication protocol. In order to ensure interoperability and allow the interchangeability of devices, all types of transmitters, actuators and analysis devices must use the standardized PROFIBUS PA protocol.

PROFIBUS technology benefits you

As a pioneer in PROFIBUS technology and a major producer of PROFIBUS instruments , Endress+Hauser is your trusted partner:

● Saved on investment costs due to shrinking scale and reduced components and cables.

● Reduce design, engineering and commissioning costs

● Reduce documentation and Ex certificate requirements

● Provide more flexibility, better measurement accuracy and higher productivity

● Improve equipment utilization through effective maintenance and repair

● Simple equipment replacement, not affected by equipment replacement

Device integration

The PROFIBUS device is connected to the PLC system via the PROFIBUS DP I/O card. The PROFIBUS PA is connected by a segment coupler and provides GSD files for system design.

To ensure seamless system integration:

● PROFIBUS devices are tested and certified in an independent laboratory certified by the PROFIBUS User Organization (PNO).

● Our equipment is tested jointly with the relevant control system under typical operating conditions.

Equipment operation and management

PROFIBUS device information (parameters, status, etc.) can be accessed in the following ways:

● FDT framework software, such as FieldCare, requires each device type to correspond to a DTM file.

● Through DD/EDD operations tools such as Asset Management Solution (AMS) and Process Device Manager (PDM).

We offer DTMs, DDs and EDDs for PROFIBUS DP and PROFIBUS PA devices and ensure their availability in the above access tools.

Device drivers and certificates

Device description files and certificates can be downloaded over the network.

PROFIBUS technical training, a comprehensive technical training course plan:

● Recognized in various industries based on actual operating experience

● Special application and practice orientation

● Independent manufacturer
