BLUETOOTH SLAVESThe 750-644 Bluetooth RF-Transceiver module provides bidirectional, wireless communication between I/O nodes. Within 10 msec, the 750-644 exchanges data up to 1, 000 m (line-of-sight) or 100 m (within buildings). One 750-644 master can communicate with up to seven slaves on a personal area network (PAN), also known as a piconet, via Bluetooth 2.0+EDR radio technology. Slave-to-slave data transmission is possible indirectly through the master. Configuration is accomplished with Wago-I/O-Check 3 software.
