Function Description
The WSA provides wireless access to the service interface of WAGO-I/O-
SYSTEM 750 fieldbus couplers and PLCs via
Bluetooth
®
Serial Port Profile
(SPP). The SPP employs two communication services “CONFIG” and “DATA”,
which use the WSA as a configuration and data connection.
If the WSA is operated in conjunction with a 750 Series WAGO PLC, a
WAGO-I/O-
PRO
program saved on the PLC can establish a wireless connection
or query diagnostic information.

The WSA can be configured via an AT command interface. This AT command
interface can be used to define settings that enable a radio link to be set up by
external devices. You can also define via this AT command interface that the
WSA is to actively set up a radio link to an external device.
