Glossary
Address
The address of a node is used to localize it in the network. It must be unique
throughout the entire system.
Aggregate current
Aggregate current of all the PA field devices.
Automation system
An automation system is a programmable logic controller that consists of at least
one CPU, various input and output modules and human-machine interfaces.
Bus
Shared transmission path to which all nodes are connected; possesses two
defined ends.
Bus connector
Physical connection between the bus node and the bus cable.
Coupler
The DP/PA coupler connects a PROFIBUS-PA segment to a PROFIBUS-DP
segment. PROFIBUS-PA and PROFIBUS-DP are linked in terms of data but are
based on different types of transmission media.
Device master file
All slave-specific characteristics are stored in a device master file (GSD file). The
format of the device master file is provided in the PROFIBUS Guideline:
Specification for PROFIBUS Device Description and Device Integration Vol.1:
GSD V4.1, 07/2001 of the PROFIBUS Nutzerorganisation (PNO).
