What is the primary purpose of a GSD (General Station Description) file in a PROFIBUS network?
Answer: To describe a slave device's capabilities and configuration parameters to a master
A GSD file provides the master with all necessary information about a slave device, including supported baud rates, I/O data structure, and configurable parameters.
Which file extension is used for PROFIBUS GSD files written in a language-specific format?
Answer: .gsde
Language-specific GSD files use the .gsde extension (for English) or similar locale extensions, while the base format uses .gsd.
In PROFIBUS DP, what is the maximum number of configurable slave modules defined in a single GSD file's module section?
Answer: 64
The GSD format supports up to 64 module entries, allowing modular slaves to describe all their available I/O slot configurations.
Which parameter in a GSD file defines the minimum station delay time a slave requires before responding to a master request?
Answer: Min_Slave_Intervall
The Min_Slave_Intervall parameter specifies the minimum time in 100 µs units between two cycles that a slave needs to process requests.
What does the 'Freeze_Mode_supp' keyword in a GSD file indicate?
Answer: The slave supports input freeze commands issued via a broadcast from the master
Freeze_Mode_supp set to 1 means the slave supports the FREEZE command, causing it to latch its input data snapshot until the master issues an UNFREEZE.
When uploading device parameters from a PROFIBUS slave using Class 2 master services, which acyclic service is used?
Answer: DPV1 Read
The DPV1 Read service (MS2 channel) allows a Class 2 master to read parameter data, diagnostics, and records from a slave on demand.
