GSDML Specification for PROFINET



The GSD (General Station Description) is the device description technology for PROFIBUS and PROFINET. It comes in two flavors:

  • The PB-GSD for PROFIBUS Masters and Slaves using GSDL (GSD Language, keyword based),


  • The PN-GSD for PROFINET Devices using GSDML (GSD Markup Language, XML based)

This specification covers the GSDML, which describes a PROFINET device regarding its identification, its structure, its communication features, its process data, its parameters, and its diagnosis.


The intended audience of this document is device manufacturers (for writing the GSD file for their devices), engineering tools manufacturers (for integrating PN Devices using GSD files), and test labs (for triggering automated tests according to the device’s GSD file content).


V2.35 adds support for Channel Related Process Alarms and Media Redundancy Ring Interconnection.
V2.35 matches PROFINET Standard V2.3 Ed2MU5.


V 2.4 adds support for Time-sensitive Networking (TSN), Remote Service Interface (RSI), Small formfactor pluggable (SFP) diagnosis, and PROFIsafe Parameterization in Run (PIR). It matches the PROFINET Specification V2.4.


Draft 2.4.1 adds GSDML signing and the element ProfileProcessAutomation.

Le nostre tecnologie

PROFIBUS è un sistema di comunicazione digitale standardizzato ed aperto, utilizzabile in tutte le aree di applicazione, dal manifatturiero al processo.

PROFINET è l'innovativo standard aperto per l'Industrial Ethernet. E' in grado di soddisfare tutti i requisiti necessari per le applicazioni di automazione industriale.

IO-LINK è la prima tecnologia IO standardizzata a livello mondiale (IEC 61131-9) per comunicare con sensori ed attuatori sotto il livello di comunicazione del bus di campo. Può essere integrata con PROFIBUS e PROFINET.
