The properties and options of an I/O device are described in a Generic Station Description
(GSD) file. This file is written in GSDML (GSD Markup Language) - an extension of XML -
and is used as a planning tool to plan the configuration for PROFINET IO systems.
PROFINET IO
PROFINET IO (Input Output) is used for controlling readers and other actuators using a
central controller in production engineering.
Proxy
A computer that receives broadcast name queries and answers to names that do not go to
the local subnet. To evaluate the names, the proxy communicates with a WINS server and
retains the names in the cache for a certain time.
RF180C
The RF180C communication module is a module for operating RFID components via
PROFINET IO on any controller.
RFID standard profile
Synonym of Ident profile.
Sensor
In electrical engineering, a sensor is a component that can qualitatively measure not only
specific physical or chemical properties (such as heat radiation, temperature, humidity,
pressure, excess pressure, sound, luminance, magnetism, acceleration, force) but also the
physical condition of its surroundings or register them as measured variables.
Server
Network station that provides services and resources for other stations, for example, a
computer that manages data and passes this on to other computers as needed.
Shutter speed: Shutter speed
The shutter speed decides how long the CCD sensor of a camera is exposed. When more
light is available, the operator can select a faster shutter speed and vice versa. At slow
shutter speeds, there is greater risk that the image will suffer from "camera shake".
SIMATIC S7
Siemens automation system with the controller families SIMATIC S7-300 and SIMATIC S7-
400.
