2.1.3 Use of the 750 Series in Compliance with Underlying

Provisions

Fieldbus couplers, fieldbus controllers and I/O modules found in the modular

WAGO-I/O-SYSTEM 750 receive digital and analog signals from sensors and

transmit them to actuators or higher-level control systems. Using programmable

controllers, the signals can also be (pre-) processed.

The components have been developed for use in an environment that meets the

IP20 protection class criteria. Protection against finger injury and solid impurities

up to 12.5 mm diameter is assured; protection against water damage is not

ensured. Unless otherwise specified, operation of the components in wet and

dusty environments is prohibited.

Operating 750 Series components in home applications without further measures

is only permitted if they meet the emission limits (emissions of interference)

according to EN 61000-6-3. You will find the relevant information in the section

on “WAGO-I/O-SYSTEM 750”  “System Description”  “Technical Data” in

the manual for the used fieldbus coupler/controller.

3 Bluetooth

®

Technology

Bluetooth

®

technology is wireless communication method based on IEEE

802.15.1. It allows license-free wireless communication in the ISM-band

frequency range between 2.402 and 2.480 GHz worldwide.

This technology is primarily used for data exchange between wireless input

devices or smartphones, but has also established itself in industrial applications.

Compared to other wireless technologies, only relatively low data rates are

achieved, but connections are very robust. Industrial implementations also allow

connections with ranges well beyond the ranges of devices for private use.

3.1 Piconet

Devices that use Bluetooth

®

technology to communicate form a so-called piconet.

One device assumes the master role and all others are slaves.

Figure 1: Piconet

Data is exchanged between the master and slave directly, but not between the

slaves themselves.

3.2 Profile and Identification

Bluetooth

®

technology can be used in many ways. Supported applications can

have very different requirements. For example, transmission of a business card or

audio signal requires different protocols. Bluetooth

®

devices normally support

only certain protocols. To make identification of suitable partners easier for

devices, profiles have been defined. Communication between devices is then

possible when both devices support the same profile.

WAGO-I/O-SYSTEM 750 Bluetooth® Technology 17

750-644 Bluetooth

®

RF-Transceiver

Manual

Version 2.0.0, valid from FW/HW Version 03/03

A standardized profile is the “Serial Port Profile” (SPP). It is used for wireless

transmission of serial interface data such as RS-232 or RS-485.

The “Service Discovery Profile” (SDP) supported by all Bluetooth

®

devices

allows a device to discover which devices are in range and to identify supported

profiles. Devices can broadcast which functions are supported by encoding such

functions as a so-called “Class of Device” (CoD) and by sharing that with other

devices. The CoD then makes it possible to look for devices with specific

functionality.

Adapter 750-921

In addition to the CoD, all devices have a MAC ID that is used to uniquely

identify the device. Many devices also allow you to choose and save a specific

name for the device. This name is then also be queried wirelessly.

In addition to standardized profiles, industrial devices sometimes also use

proprietary profiles to meet specific requirements, e.g. in terms of reliability.

3.3 Security

Compatibility, connectivity and the security of radio communication are high

priorities for Bluetooth

®

technology. Due to the wide variety of devices and

applications that the technology uses, configurations can arise where devices are

unable to communicate with each other because of the different security

mechanisms implemented. This can affect devices, for example, that have no

configuration options for reasons of cost or devices that do not allow direct user

interaction based on their design.

tation.

RF-Transceiver

Manual

Table 5: Terms used

Term

Explanation

Local

A component or device to which there is a wired connection.

Example: A 750-644 I/O module represented in WAGO-I/O-

CHECK on the operator PC.

Remote

A component or device to which there is no wired connection.

Communication

partner

A remote device (from the perspective of the local device) or

the local device (from the perspective of a remote device).

In range

Devices or components are in range when transmitter and

receiver are mutually so strong or sensitive that

communication is technically possible. Whether

communication actually occurs depends on several other

factors, e.g. if radio connection is even wanted or if security

settings are compatible.

Allowed

For secure connections, communication is only possible with

devices defined as “authorized devices”. Bluetooth

®

technology designates devices that view each other as

“authorized devices”, as well as “paired” or “coupled”.

Visible

Describes a Bluetooth

®

device that responds to scans from

any other Bluetooth

®

device. A device that is not visible only

responds to scans or connection attempts when such attempts

come from authorized devices.

Connectable

Describes a Bluetooth

®

device to which connections can be

established. Sometimes it may not be possible for authorized

devices to connect to a Bluetooth

®

device. This is the case,

for example, when the device is designed or configured to

allow only a certain number of simultaneous connections and

that number has already been reached.

Connected

Describes a state in which devices are able to exchange data

with each other. To do so, the devices must be in range. If the

devices have a secure connection, the connection must be

between authorized devices.

Authentication

Refers to the process of mutual verification of two Bluetooth

®

devices, where each device determines if the other is an

authorized device. Part of the process can be user interaction,

e.g. display of a dialog box on a smartphone or access to a

saved configuration that indicates which devices are and are

not allowed.

The Bluetooth

®

RF Transceiver 750-644, hereafter referred to as the 750-644 I/O

module, is used to integrate a Bluetooth

®

network (Piconet) in the WAGO-I/O-

SYSTEM 750. 750-644 modules are installed and used jointly with other I/O

modules of the WAGO-I/O-SYSTEMs 750 in different fieldbus systems.

The 750-644 I/O module permits wireless exchange of data 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.

In piconets consisting of 750-644 I/O modules exclusively, the I/O modules can

use a specific proprietary profile for communication. If using the WAGO 758-912

antenna, ranges of up to 1000 meters can be achieved. In addition to particularly

robust, deterministic radio communication, expanded diagnostic functions are also

available.

The 750-644 I/O module can communication with devices from different

manufacturers that support the protocols of the SPP profile, i.e. the wireless

transmission of serial interface data. Apps are available that allow smartphones to

exchange data with the 750-644 I/O module.

The WAGO-I/O-CHECK software is used to configure the 750-644 I/O module

locally (network configuration, process image mapping). Eight 3-color LEDs

indicate the current status of the 750-644 I/O module.
