Firmware update
Updating the firmware of modules (interface modules, I/O modules, etc.), for example after
functional expansions, to the latest firmware version (update).
Function
A function (FC) is a code block with no static data. A function allows you to pass parameters
in the user program. Functions are thus suited for programming frequently recurring complex
functions, such as calculations.
Function block
A function block (FB) is a code block with static data. An FB allows you to pass parameters
in the user program. Function blocks are thus suited for programming frequently recurring
complex functions, such as closed-loop controls or operating mode selection.
Functional ground
The functional ground is a low-impedance current path between electric circuits and ground.
It is not intended as a protective measure but rather, for example, for improvement of
interference immunity.
Ground
Conductive earth whose electrical potential can be set equal to zero at any point.
All interconnected, inactive parts of a piece of equipment that cannot accept any dangerous
contact voltage, even in the event of a fault.

Grounding
Grounding means connecting an electrically conductive part to a grounding electrode by
means of a grounding system.
GSD file
The Generic Station Description file contains all properties of a PROFINET or PROFIBUS
device that are necessary for its configuration.
Hardware interrupt
