Process interrupt
A process interrupt is triggered by interrupt-triggering modules as a result of a specific event
in the process. The process interrupt is reported to the CPU. The assigned organization
block will be processed according to interrupt priority.
Process-Related Function

Product version
The product version identifies differences between products which have the same order
number. The product version is incremented when forward-compatible functions are
enhanced, after production-related modifications (use of new parts/components) and for bug
fixes.
PROFIBUS
Process Field Bus - European fieldbus standard.
See PROFIBUS DP

PROFIBUS Device
A PROFIBUS node has at least one or more PROFIBUS ports.
A PROFIBUS device cannot take part directly in PROFINET communication but must be
included over a PROFIBUS master with a PROFINET port or an Industrial
Ethernet/PROFIBUS link (IE/PB Link) with proxy functionality.
See Device
PROFIBUS DP
A PROFIBUS with the DP protocol that complies with EN 500170. DP stands for distributed
peripheral I/O (fast, real-time, cyclic data exchange). From the perspective of the user
program, the distributed I/O is addressed in exactly the same way as the central I/O.

PROFIBUS International
Technical committee that defines and further develops the PROFIBUS and PROFINET
standard.
Also known as the PROFIBUS User Organization (PNO).
