Page 18: Function Description
(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. -
Page 19: Radio Interface
WAGO-I/O-SYSTEM 750 Function Description ® 750-921 Bluetooth Adapter The WSA can be used without previously being configured via the AT command interface. For this, the WSA can be switched to other special operating modes by targeted interruption of power supply at specific intervals. In these operating modes, processes are initiated which adapt the configuration automatically as required. -
