WAGO-I/O-SYSTEM 750 Function Description 37750-644 Bluetooth® RF-TransceiverManualVersion 2.0.0, valid from FW/HW Version 03/035.1.1 “Configuration” ModeIn “Configuration” mode, all parameters of the 750-644 I/O module areconfigured, e.g. via WAGO-I/O-CHECK or function blocks of WAGO-I/O-PROCAA. Alternatively, the I/O module can also be configured via the process imagedirectly. The Mailbox protocol is used for this purpose. A description of allMailbox commands is available in the appendix under “Mailbox Commands”.Of particular importance is configuration of the settings that define with whichremote 750-644 I/O modules or remote Bluetooth ® SPP devices a radioconnection should be set up. These settings are summarized under the term “NetForming” (see section “Function Description” > … > “Net Forming”).In “Configuration” mode, no data connection is established with remote 750-644I/O modules or remote Bluetooth® SPP devices. All process data assigned to therespective slots have the content “0”. However, a Bluetooth® inquiry can be usedto scan for remote 750-644 I/O modules or remote Bluetooth ® SPP devices and aquery to identify the MAC ID and device name.5.1.2 “Real-Time Communication” ModeIn “Real-Time Communication” mode, the 750-644 I/O module uses a proprietaryreal-time profile for radio communication. Operation in this mode has thefollowing characteristics:• Automatic connection to and communication with up to 7 other 750-644 I/Omodules• Cyclical transmission of assigned information of the output process image(PIO)• Long ranges are possible• Deterministic latency and cycle time• Monitoring the timing using software watchdog5.1.3 “Ad-hoc Communication” ModeIn “Ad-hoc Communication” mode, the 750-644 I/O module uses the standardized“Serial Port Profile” (SPP) for radio communication with remote Bluetooth ® SPPdevices. Operation in this mode has the following characteristics:• Manual connection to and communication with up to 6 remote Bluetooth®SPP devices• Serial transmission of information• Flow control by handshake bytes (HS bytes)• Range is determined in each case by the weakest devicePos : 68.4 /Serie 750 (WAGO-I/O-SYST EM)/F unktions beschr eibung/Funkti onsbesc hrei bung 750-0644 - Funksc hnitts tell e/N et F or ming @ 16\mod_1376487092128_21.doc x @ 128851 @ 2344 @ 15.2 Radio InterfaceThe 750-644 I/O module permits wireless exchange of data with remote devicesusing version 2.0 of the Bluetooth® standard.The following profiles are supported for communication:
