Firmware update
Upgrade of firmware for modules (interface modules, I/O modules etc.), e.g. after function
extensions, to the newest firmware version (update).
F-monitoring time

Functional ground
Functional ground is a low-impedance current path between electric circuits and ground. It is
not designed as a safety measure but instead, for example, as a measure to improve
interference immunity.
Ground
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
As a Generic Station Description, this file contains all properties of a PROFINET or
PROFIBUS device that are necessary for its configuration in XML format.
I/O modules
All modules, with the exception of the motor starters, 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.
Infeed system
The infeed system with the terminals L1(L), L2(N), L3, PE enables several SIMATIC
ET 200SP motor starters to be supplied using a single infeed terminal.
