1.4 Safety Notes
Warning
Switch off the system prior to working on bus modules!
In the event of deformed contacts, the module in question is to be replaced, as
its functionality can no longer be ensured on a long-term basis.
The components are not resistant against materials having seeping and
insulating properties. Belonging to this group of materials is: e.g. aerosols,
silicones, triglycerides (found in some hand creams).
If it cannot be ruled out that these materials appear in the component
environment, then additional measures are to be taken:
- installation of the components into an appropriate enclosure
- handling of the components only with clean tools and materials.
Attention
Cleaning of soiled contacts may only be done with ethyl alcohol and leather
cloths. Thereby, the ESD information is to be regarded.
Do not use any contact spray. The spray may impair the functioning of the
contact area.
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access must only be given via a key or tool to authorized qualified
personnel.
The relevant valid and applicable standards and guidelines concerning the
installation of switch boxes are to be observed.
ESD (Electrostatic Discharge)
The modules are equipped with electronic components that may be destroyed
by electrostatic discharge. When handling the modules, ensure that the
environment (persons, workplace and packing) is well grounded. Avoid
touching conductive components, e.g. gold contacts.

Description
WAGO-I/O-SYSTEM 750
I/O Modules
2.1.1.2 Description
The 750-642 Radio Receiver module receives digital and analogue sensor
signals from the field area by radio link.
Danger
The radio receiver modules must not be used in any relation with equipment
that supports, directly or indirectly, human health or life or with applications
that can result in danger for people, animals or real value.
This results from the classification of the radio receiver module in class 2
Equipment according to ETSI EN 301 489-3 V1.4.1 (2202-08) "Specific
conditions for short-range devices (SRD)".
The module receives the radio transmitter data via an antenna with a carrier
frequency of 868.3 MHz situated outside the enclosure.
For this an antenna equipped with an SMA plug (WAGO RF ANTENNA
868 MHz/SMA, Item-no.: 758-910) is connecting to the SMA socket fitted to
the module.
Attention
The WAGO RF-ANTENNA 868MHz/SMA is not included in delivery of the
Radio Receiver module!
It is to order separately as accessories under the Item-No.: 758-910.
The module has two potential free CAGE CLAMP®connections (1 and 2)
without electrical function. These make the mechanical fixing of the antenna
line possible.
Attention
Mechanical stress such as vibration or shock may cause wire breakage. For
that reason, appropriate action needs to be taken to fix the antenna cable (see
chapter 2.1.1.9 "Installation in Case of mechanical Stress (Vibration,
Shock)".
The applications for this module are, for example, in operator, control and
signaling systems in building automation (office, exhibition halls, private
households...), in cabin automation on ships, and anywhere sensors (radio
transmitters) require intelligent controllers or gateways to other bus systems.
The revolutionary EnOcean radio technology offers the decisive advantage
that the specially developed sensors have very low power consumption.
They require no external power supply or batteries for radio transmission. This
means that the sensors need no servicing (battery replacement), can be
installed retrospectively without difficulty and, due to the wireless technology,
can be freely positioned, even on glass facades.
For the necessary electrical energy, the sensors use either mechanical energy
converted by piezo elements or solar energy. This provides sufficient energy
for the respective sensor to send a unidirectional radio signal.
The number of sensors can be chosen virtually at will, although the maximum
per module is around 100 sensors due to increasing density with growing
numbers.

I/O Modules
Further Information
Partner sites for suppliers of radio sensors and other accessories for the radio
technology can be found at www.enocean.com (References/Partners).
To be able to use the installed radio transmitters for an application, these must
be uniquely identified. With some sensors, the ID can be directly read from
the back of the sensor. If this is not the case, the 32-bit ID code of the sensor
can be read using an IEC 61131-3 application. The IEC application can be
implemented in the connected programmable fieldbus controller (PFC) of the
fieldbus node using the WAGO-I/O-PRO programming tool or, where a
fieldbus coupler is connected, in a primary controller.
The data of individual sensors is not mapped in the process image of the
connected coupler/controller, but packaged in EnOcean radio telegrams and
tunneled unmodified to a function block of the application, via an internal
RS 232 interface. The function block decodes the messages to enable the
analogue or digital sensor data to be interpreted and processed at application
level.
LEDs indicate the operational readiness of the module and fault-free
communication on the internal data bus.
Any configuration of the modules is possible when designing the fieldbus
node. Grouping of module types is not necessary.
Attention
This module has no power contacts. For field supply to downstream I/O
modules, a supply module will be needed
Note
The receiver module cannot be used in a combination of LONWORKS®
fieldbus coupler 750-319 with WAGO TOPLON®IF and PRIO plug-ins.
The module is directly supported by the controllers of the
WAGO-I/O-SYSTEM 750. Where a coupler is used, the use of a primary
controller is necessary for control of the module.
This module can be used with all couplers/controllers of the
WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, -323, -324
and -327).

WAGO-I/O-SYSTEM 750
I/O Modules
2.1.1.6 Process Data
The data of individual sensors is not mapped in the process image of the
connected coupler/controller, but packaged in EnOcean radio telegrams and
tunneled unmodified via an internal RS 232 interface to the application.
The EnOcean Radio Receiver module maps 4 data bytes into both the input
and output areas of the process image of the coupler/controller (in exactly the
same way as the WAGO RS 232 interface module, part no.: 750-650).
Up to 3 input bytes are employed for transfer of the received data. Since the
transmit channel of the interface is not used, the 3 bytes for output data are
unused.
The additional control and status byte of the module is used for the handling
of the data transmission on the internal I/O bus.
An EnOcean radio telegram tunneled by means of these data bytes has a total
length of 14 bytes. These include a 32-bit sensor ID number, up to 4 bytes of
sensor data depending on the type of sensor and CRC (cyclic redundancy
checksum) as error control procedure.
As a result, several module bus cycles are required to completely map the
message in the controller or primary controller.
Depending on whether the module is used in a fieldbus node with PFC or with
a coupler and primary controller, different detail information is relevant for
the accessing and interpretation of the process data.
2.1.1.6.1 For PFC Application
Appropriate IEC 61131-3 function blocks are available for WAGO-I/O-PRO
for reading the process data via the controller.
In the WAGO-I/O-PRO application, the function block ENOCEAN_RECEIVE
receives the data packets arriving from several module bus cycles.
After assembling the packets into a radio telegram, this block tests the message
for checksum errors.
Further function blocks then interpret and process the message content.
Further Information
The function blocks for WAGO-I/O-PRO can be downloaded free of charge
from the Internet. These can be found at:

to read the ID of PTM sensors.
At the input of this block, you enter how many buttons must be
simultaneously pressed to cause the block to display the transmitter IDs
contained in the radio telegram at the output. Radio telegrams in which, for
example, only one button is pressed, are ignored.
Identification of digital and analogue Sensors
The function block ENOCEAN_SHOW_ID_BY_CLICK is used to read the
32-bit ID code of digital and analogue sensors.
At the input of this block, you first enter the type of sensor (PTM, STM or
CTM) of which the ID is to be read. In addition, you enter how often a button
must be pressed so that the block displays the transmitter IDs contained in the
radio telegram at the output. Radio telegrams in which only one button is
pressed, are ignored.

**)The bit SR is used only when the lower 3 bits from ID_BYTE0 = ’111’ (scene switch), and RID ≠0
(indicates that the memory buttons M0-M6 are operated in the handled remote control.
2.1.1.7 Notes on Application
Danger
The radio receiver modules must not be used in any relation with equipment
that supports, directly or indirectly, human health or life or with applications
that can result in danger for people, animals or real value.
This results from the classification of the radio receiver module in class 2
Equipment according to ETSI EN 301 489-3 V1.4.1 (2202-08) "Specific
conditions for short-range devices (SRD)".
Attention
The use of the devices does not need to be registered and is free in the
European Union, Switzerland, Cyprus, the Czech Republic, Poland and in
Slovenia.
The use in other countries requires explicit clarification!

2.1.1.8 Notes on Installation
Avoid installing the module, the antenna and the antenna line close to sources
of transient interferences, such as fluorescent tubes with defective starter,
frequency converters and power cables. As a result, communication failures
may occur leading to faulty digital and analog values.
Notes on external Antenna Installation
1) Use only suitable antennas.
Recommended is the WAGO RF-ANTENNA 868MHz/SMA.
Attention
The WAGO RF-ANTENNA 868MHz/SMA is not included in delivery of the
radio receiver module!
It is to order as accessories under the Item-No.: 758-910.
2) The antenna is to be mounted on a plate measuring at least 9.8 x 9.8 inches
(25 x 25 cm).
3) The distance of interfering sources to the antenna and antenna line must be
at least 11.8 inches (30 cm) and the free space between the antenna and the
next wall must be at least 13.78 inches (35 cm).
4) The antenna cable should, under no circumstances, be bent sharply, since
irreversible damage may result to the antenna line (RG174 bend radius >
0.6 inches/15 mm).
Notes concerning Antenna Extension
Antenna kits are provided by EnOcean if an antenna extension is required.
