PROFIBUS is the fieldbus-based automation standard of PROFIBUS & PROFINET International (PI). Via a single bus cable, PROFIBUS links controller or control systems with decentralized field devices (sensors and actuators) on the field level and also enables consistent data exchange with higher ranking communication systems.

PROFIBUS and PROFINET International (PI) is the world's leading industry association, the active community for the development, standardization and dissemination of industrial communication and automation technologies, a core topic of digitalization.

GSD files have a standard file format, which is described in the PROFIBUS guidelines. PNO has developed a GSD Editor to assist the manufacturer when setting up GSD files for PROFIBUS DP slave devices. The editor includes a syntax and semantics check according to …

PROFIBUS is a standardized, open, digital communication system for all areas of application in manufacturing and process automation. PROFINET is the innovative open standard for Industrial Ethernet. It satisfies all requirements of automation technology.

The IEC 61508-compliant technology has been developed under PROFIBUS & PROFINET International (PI) and is worldwide established. PROFIsafe has become an international standard (IEC 61784-3-3) and has been evaluated positively by …

An example of PI’s close relationships with other automation organizations is IO-LINK, which is an independent sensor / actuator interface solution for use with PROFIBUS and PROFINET. IO-LINK is a point-to-point interface for the low-cost connection of smart/intelligent devices serving the lowest level of automation (see right - click the ...

The DP/PA Coupler interconnects PROFIBUS DP to PROFIBUS PA lines. Transmission rate on PROFIBUS DP is fix to 45,45 kBit/sec. The field devices are addressed directly by the programmable controller; the DP/PA coupler is transparent.

These GSD files allow easy configuration of PROFIBUS networks with devices from different manufacturers. GSD is a human readable ASCII text file. Keywords are specified as mandatory or optional with the corresponding data type and their border values to support the configuration of PROFIBUS devices.

PROFINET diagnostics are based on the proven concepts of PROFIBUS and have been extended by Ethernet specific functionalities, especially for network diagnostics. With the new possibilities of Ethernet based networks, diagnostics also get accessible via web tools.

An Ident Number (ID number) is required for all PROFIBUS devices using PROFIBUS DP communication (except Master Class 2 devices). Manufacturers must register each device type with PI and get either a manufacturer and/or profile specific ID number.
