A programmable logical controller (PLC) of the SIMATIC S7 system, comprising a central
controller, a CPU and various I/O modules.

Communication modules
Communication modules are used to integrate the MOBY identification systems in SIMATIC
or SINUMERIK systems, or to connect them to PROFIBUS DP, PC or any other system.
Once supplied with the corresponding parameters and data, they handle data
communication. They then make the corresponding results and data available. Suitable
software blocks (FB/FC for SIMATIC; C libraries for PCs with Windows Professional) ensure
easy and fast integration in the application.
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 write/read device. The write/read device can exchange data with the transponder during
this time.
