260 Function Manual, 12/2017, A5E03444486-AH
In the PROFINET environment, "device" is the generic term for:
● Automation systems (for example, PLC, PC)
● Distributed I/O systems
● Field devices (for example, PLC, PC, hydraulic devices, pneumatic devices)
● Active network components (for example, switches, routers)
● Gateways to PROFIBUS, AS interface or other fieldbus systems
Device name (PROFINET device name)
In the PROFINET IO environment, the device name is a unique identifier for the
PROFINET IO interface of a device.

System diagnostics
The diagnostics buffer represents a backup memory in the CPU, used to store diagnostics
events in their order of occurrence.
Diagnostics error interrupt
Modules capable of diagnostics operations report detected system errors to the CPU by
means of diagnostics interrupts.

A master which behaves in accordance with EN 50170, Part 3, is known as a DP master.
→ See also Master
A slave operated on PROFIBUS with PROFIBUS DP protocol and in accordance with
EN 50170, Part 3 is referred to as DP slave.
→ See also Slave
The designation DPV1 refers to the functional extension of acyclic services (to include new
interrupts, for example) provided by the DP protocol. The DPV1 functionality is integrated in
IEC 61158/EN 50170, Volume 2, PROFIBUS.
