2.1.1.2 Description
The Bluetooth
®
RF Transceiver 750-644 (referred to in the following as "Blue-
tooth
®
module") integrates a Bluetooth
®
network (piconet) into the WAGO-
I/O-SYSTEM 750. This means that Bluetooth
®
modules will be installed and
used jointly with the WAGO-I/O-SYSTEM 750 modules in different fieldbus
systems.
The Bluetooth
®
module facilitates wireless
data exchange within the Bluetooth
®
piconet.
It can function as the coordinator (referred to
in the following as the "master") or as the
terminal (referred to in the following as the
"slave") depending on the configuration. A
maximum of seven slaves may communicate
with one master (see
Figure 2).

The module's configuration (network configuration/process image mapping) is
determined locally via WAGO-I/O-CHECK software.
The current status of the module is displayed by LEDs. While the LEDs asso-
ciated with the function of "slave" signal the quality of the connection, the
LEDs associated with the "master" function show the connection status to
each individually connected slave.
