etwork
A communication system for industrial Ethernet based on the DIAS-BUS
developed by Sigmatek. The system is supported by the VARAN-BUS-
NUTZERORGANISATION (VNO).
Watchdog Timer
A watchdog timer provides an internal supervision mechanism of a
communication system. It supervises that an important event happens
within a given timeframe (the watchdog time which can be adjusted
accordingly, for instance by a parameter in the
_Warmstart
message) and
causes an alarm otherwise (usually this is accomplished by changing the
operational state of the communication system to a more safe state).
XDD file
A special kind of Device Description file used by Ethernet Powerlink.
XML
XML means Extended Markup Language. It is a symbolic language for
structuring data systematically. XML is standard maintained by the W3C
(World-wide web consortium). Device Description Files often use XML-
based formats for storing the device-related data appropriately.
