Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, solutions, machines, equipment and/or networks. They are
important components in a holistic industrial security concept. With this in mind, Siemens’
products and solutions undergo continuous development. Siemens recommends strongly
that you regularly check for product updates.
For the secure operation of Siemens products and solutions, it is necessary to take suitable
preventive action (e.g. cell protection concept) and integrate each component into a holistic,
state-of-the-art industrial security concept. Third-party products that may be in use should
also be considered. For more information about industrial security, visit

Connection using mobile wireless, Internet and GPS
Wireless connection via the mobile wireless network
With the CMR, you establish a mobile data connection to a mobile wireless network: LTE,
UMTS or GSM/GPRS mobile wireless network. You are also in a position to connect the
CMR to a GPS system.
With the CMR, you can do the following:
● Read the information of a BM using SMS: Process image, inputs/outputs, memory bits
and much more
● Notify event-based using SMS.
The CMR is connected locally to a BM via Ethernet and establishes the connection to a
mobile wireless network.
You can also operate the CMR in stand-alone mode: in other words without a connected BM.
To connect the I/O you use the two inputs and outputs of the CMR.
Mobile wireless network within reach
● To be able to send and receive SMS messages, there must be a reachable mobile
wireless network.
Sending SMS messages
● You require a SIM card from a mobile wireless provider. The SIM card must be activated
for sending SMS messages. This SIM card must have a telephone number.
Time-of-day synchronization with NTP
● You require a SIM card with mobile data options: This SIM card does not need to have a
telephone number.
● You require a mobile wireless network within reach that supports the exchange of mobile
data.
You configure the CMR locally using a Web user interface (WBM) that can be displayed with
a Web browser:
1. Connect a PC to the "X1P1 IE (LAN)" connector of the CMR. To do this, use an Ethernet
2. Start the Web user interface as described in the section Configuration (Page 47).
Using WBM you can view a diagnostics buffer for diagnostics purposes. Is also possible to
download and save the diagnostics buffer on an SD card or PC.
The following are logged, for example:
● Operating messages such as startup, change to the configuration.
● Establishment/interruption of the connection to the BM.
● Establishment/interruption of the connection to the mobile wireless network.
● Establishment/interruption of the mobile data connection.
● Warnings when reading in the configuration from an SD card or from the PC.
– Fallback* to 3G (UMTS, HSUPA and HSDPA): 900 MHz (B8), 2100 MHz (B1)
– Fallback* to 2G (GSM/GPRS): 850 MHz, 900 MHz, 1800 MHz or 1900 MHz
* Fallback to the next lower standard (LTE > UMTS > GSM/GPRS and EDGE)
If you want to use GPS, you require an additional GPS antenna:
● Only use antennas from the accessories program for the CMR. For more information,
refer to the section Antenna and cabling technology for LOGO! CMR (Page 137).
You require a power supply with a voltage between 12 VDC and 24 VDC that provides
adequate voltage or current. For more information, refer to the section Technical
specifications (Page 143).
There is an additional requirement if devices are operated with a redundant power supply:
External power supply
NOTICE
Power supply
The following safety notices must be adhered to when setting up and operating the device
and during all associated work such as installation, connecting up or replacing devices.
The equipment is designed for operation with Safety Extra-Low Voltage (SELV) by a
Limited Power Source (LPS). (This does not apply to 100 V...240 V devices.)
This means that only SELV / LPS complying with IEC 60950-1 / EN 60950-1 / VDE 0805-1
must be connected to the power supply terminals. The power supply unit for the equipment
power supply must comply with NEC Class 2, as described by the National Electrical Code
(r) (ANSI / NFPA 70).
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
● Use only an external power supply that complies with EN 60950.
● The output voltage of the external power supply must not exceed 30 VDC.
● The output of the external power supply must be short-circuit proof.
The power supply unit to supply the CMR must comply with the requirements for a limited
power source according to IEC/EN 60950-1, section 2.5.
The external power supply for the CMR must meet the requirements for NEC class 2
circuits as specified in the National Electrical Code ® (ANSI/NFPA 70).
Note the information in this section and in the installation and operating instructions from the
manufacturer of the power supply.
L+ = live wire, positive pole of the DC voltage 12/24 VDC
②
M = negative pole/ground of the DC voltage 12/24 VDC
③
Note
Power supply unit of the CMR is not electrically isolated
No electrical isolation means that the input and output circuits are not galvanically is
4.1 Power supply
If power is supplied to the module or station over longer power cables or networks, the
coupling in of strong electromagnetic pulses onto the power supply cables is possible. This
can be caused, for example by lightning strikes or switching of higher loads.
The connector of the external power supply is not protected from strong electromagnetic
pulses. To protect it, an external overvoltage protection module is necessary. The
requirements of EN 61000-4-5, surge immunity tests on power supply lines, are met only
when a suitable protective element is used. A suitable device is, for example, the Dehn
Blitzductor BVT AVD 24, article number 918 422 or a comparable protective element.
The interface supports autonegotiation and autocrossing. For the connection, use a patch
cable with an RJ-45 plug. You will find the properties of the X1P1 interface in the technical
specifications.
● Connect your local area network, the PC or the BM to X1P1 (LAN) of the CMR.
The CMR has two inputs and two outputs. The connecting terminals are on the underside of
the device.
The connecting terminals of the inputs are labeled I1 and I2. The reference potential for both
inputs is "M".
Using the Web user interface, you can assign any function to each input, for example
triggering an alarm SMS message (Page 94).
The status of an input can also be read using SMS.
The connecting terminals of the outputs are labeled Q1 and Q2. The reference potential for
both outputs is "M".
You can assign any function (Page 94) to each output using the Web user interface. The
outputs can be set and reset using SMS messages.
You will find the electrical values for the inputs and outputs in the section Technical
specifications (Page 143).

4.3 SMA antenna sockets
If you install an antenna outside, you need to ground the antenna to protect it from lightning
strikes. This work must only be carried out by qualified personnel.
Select the antenna suitable for your frequency band from the accessories. Other antennas
could interfere with product characteristics or lead to defects.
The CMR has two antenna sockets of the type SMA for connecting the antennas. The
antennas must have an impedance of approx. 50 Ω.
Follow the operating instructions of the antennas used. See also section Antenna and
cabling technology for LOGO! CMR (Page 137).
Depending on the frequency bands your mobile wireless provider uses:
● Select the antenna suitable for your frequency band from the accessories (Page 137).
During installation make sure that there is a good signal strength:
● If the "R" LED is lit green or flashes green, the signal strength is very good.
● Lit yellow or flashing yellow signals medium quality.
● If the "R" LED is not lit, this indicates an inadequate signal strength, refer also to the
section LEDs to display operation (Page 19).
Large metallic objects in the vicinity of the antennas, for example reinforced concrete, impair
the signal strength.
