Automation system (AS)
A programmable logical controller (PLC) of the SIMATIC S7 system, comprising a central
controller, a CPU and various I/O modules.
Battery-free data storage unit
Mobile data storage units which operate without batteries. Power is supplied to the data
storage unit across an electromagnetic alternating field.
Byte
A group of eight bits forms a byte
CE marking
Communauté Européenne (product mark of the European Union)
Communication modules
Communication modules ensure the integration of the MOBY and SIMATIC RF identification
systems into SIMATIC, SINUMERIK, SIMOTION, PROFIBUS, PROFINET and TCP/IP.
Once supplied with the corresponding parameters and data, they handle data
communication. They then make the corresponding results and data available.
Corresponding software blocks (FBs/FCs for SIMATIC) guarantee simple and quick
integration into the application.
Data transmission rate
Unit of measurement for the volume of data transmitted within a unit of time, e.g. bytes/s
Detection area
Area with minimum field strength containing the transmission window, as well as the areas in
which the field strength is no longer sufficient for data exchange.
Dwell time
The dwell time is the time in which the transponder dwells within the transmission window of
a read/write device. The read/write device can exchange data with the transponder during
this time.
