GSD file
As a Generic Station Description, this file contains all properties of a PROFINET device that
are necessary for its configuration in XML format.
I/O modules
All modules that can be operated with a CPU or an interface module.
Identification data
Information that is saved in modules and that supports the user in checking the plant
configuration and locating hardware changes.
Interface module
Module in the distributed I/O system. The interface module connects the distributed I/O
system to the CPU (IO controller) via a fieldbus, and prepares the data for and from I/O
modules.
Load power supply
Supply of modules like the interface module, power supply modules, I/O modules, and (if
applicable) sensors and actuators
MAC address
globally unique device identifier, which is already assigned to each PROFINET device in the
factory. The 6 bytes of the address consist of a 3-byte manufacturer ID and a 3-byte device
ID (serial number). The MAC address is usually clearly legible on the device.
