The topics covered will be Profibus, Profinet, Profisafe, FDT/DTM.
Fieldbus suppliers are moving in three different development directions simultaneously, and these are covered by the three aspects of Profibus.
Profibus provides the interface to individual discrete I/O using interface to ASI (Actuator Sensor Interface) bus for manufacturing applications, and Profibus-PA offers a similar functionality for process applications.
As the distribution devices continue to individual I/O levels, and addition of start buttons, stop buttons, pilot lights, proximity sensors, and measuring instruments directly onto the fieldbus continue to grow, the maintenance, diagnostics, configuration, and calibration of these devices need to be addressed by the fieldbus.
Profinet is the Ethernet-based automation standard of Profibus International.
It is a component-based model, and offers Soft Real Time transfer of data using TCP/IP.
Up until recently, Ethernet was mainly used in office automation: as the non-deterministic issue of Ethernet is addressed by switching technologies and the higher speeds, the gap between office automation and industrial automation begins to diminish, and fieldbuses are expected to move to what was the IT domain not so long ago.
Profisafe is an additional software layer to ensure the reliability of the message delivery.
Generally hard-wired systems, and dedicated fieldbuses have been used in safety related applications in the past: there is move to use fieldbus for most of these applications, which entails the introduction of new hardware and software layers to increase functionality of the fieldbus to operate in safety related areas.
The main presenter is Dr Manfred Popp who is well known authority on Profibus and related technologies.
