Glossary
Active field
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.
Active surface
See active field
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 memory
Mobile data memories which operate without batteries. Power is supplied to the data
memory across an electromagnetic alternating field.
CE mark
Communauté Européenne (product mark of the European Union)
Data transmission rate
Unit of measurement for the volume of data transmitted within a unit of time, e.g. bytes/s
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.
Dynamic mode
In dynamic mode, the data carrier moves past the read/write device at a traversing rate
which depends on the configuration. Various checking mechanisms (listen-in check, CRC,
ECC, etc.) ensure error-free data transfer even under extreme environmental conditions. A
serial connection (up to 1000 m) is used to connect the read/write device directly to an
interface module, PC, or any other system.
