1.1 Security information
Siemens provides products and solutions with industrial security functions that support the
secure operation of plants, systems, machines, and networks.
In order to protect plants, systems, machines and networks against cyber threats, it is
necessary to implement – and continuously maintain – a holistic, state-of-the-art industrial
security concept. Siemens’ products and solutions form one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. These systems, machines and components should only be
connected to the enterprise network or the Internet if and only to the extent necessary and
with appropriate security measures (firewalls and/or network segmentation) in place.
You can find more information on protective measures in the area of industrial security by
visiting:
https://www.siemens.com/industrialsecurity.
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends performing product updates as soon as they are
available and using only the latest product versions. Use of product versions that are no
longer supported, and failure to apply latest updates may increase customer’s exposure to
cyber threats.

3.1 Important notes on using the device
Safety notices on the use of the device
The following safety notices must be adhered to when setting up and operating the device
and during all work relating to it such as installation, connecting up, replacing devices or
opening the device.
General notes
WARNING
Safety extra low voltage
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).
There is an additional requirement if devices are operated with a redundant power
supply:
If the equipment is connected to a redundant power supply (two separate power supplies),
both must meet these requirements.
WARNING
Opening the device
D not open the device when energized.

12 Operating Instructions, 02/2021, C79000-G8976-C328-03
Overvoltage protection
NOTICE
Protection of the external 24 VDC voltage supply
If the module is supplied via widespread 24 V power supply cables or networks, coupling of
strong electromagnetic pulses into the power supply cables is possible, for example due to
lightning or the switching of large loads.
The connection of the external 24 VDC power supply is not protected against strong
electromagnetic pulses. Make sure that any cables liable to lightning strikes are fitted with
suitable overvoltage protection.
3.2 Installing and commissioning the RF120C
Prior to installation and commissioning
WARNING
Read the system manual "S7-1200 Programmable Controller"
Prior to installation, connecting up and commissioning, read the relevant sections in the
system manual "S7-1200 Programmable Controller". When installing and connecting up,
keep to the procedures described in the system manual "S7-1200 Programmable Controller".
Make sure that the power supply is turned off when installing/uninstalling the devices.
Parameter assignment
One requirement for the commissioning of the CP is the completeness of the STEP 7 project
data. For more information, read the section "Configuration and parameter assignment
(Page 21)".

Procedure for installation and commissioning
Note
Installation location
All RF120C communications modules must be installed to the left beside the SIMATIC S7
-
1200. During installation, make sure that the upper and lower ventilation slits of the module
are not obstructed and good ventilation is possible. A
bove and below the device, there must
be a clearance of 25 mm to allow air to circulate and prevent overheating.
Remember that the permitted temperature ranges depend on the position of the installed
device.
Device position / permitted temperature range
Installation location
Horizontal installation of the rack:
0 °C to 55 °C
Vertical installation of the rack:
0 °C to 45 °C
NOTICE
Connection with power off
Wire up the SIMATIC S7-1200 and modules to be connected only when the power is off.
Note
Power supply from the power outputs of the CPU
Connected modules obtain their power via the backplane bus of the SIMATIC S7
-1200.
Readers or code reading systems connected to the CM require an additional external power
supply via the CM. Keep within the maximum load of the power outputs of the CPU.
You
will find data relating to the current consumption and power loss of the CM in the
section "
Technical data (Page 33)".
The RF120C communications module must be grounded via the shield.

Task
Procedure
1. Remove the bus cover on the left of the CPU:
–Insert a screwdriver into the slot above the bus cover.
–Lever the cover up carefully out of its mounting.
Remove the bus cover. Put the cover away for later use.
2. Connect the RF120C to the CPU:
–Align the bus connector and the pins of the RF120C with the drill holes in the
CPU.
–Press the components together firmly until the limit stop is reached.
3. Fit the CPU with the connected modules onto the 35 mm DIN rail and secure the
DIN rail.
4. Secure the power supply wires to the external power supply unit.
5. Secure the wires of the external power supply to the plug supplied with the
RF120C and insert the plug in the socket on the top of the RF120C.
The pinning is shown beside the socket on the top of the housing. You will also
find this in the section "Pin assignment of the socket for the external power supply
(Page 20)".
6. Connect the reader using the RF120C cable to the D-sub female connector of the
RF120C. To do this, open the lower door in the housing.
7. Turn on the power supply.
8. Close the front covers of the module and keep them closed during operation.
9. The remaining steps in commissioning involve downloading the STEP 7 project
data.
The STEP 7 project data of the RF120C is transferred when you download to the sta-
tion. To load the station, connect the engineering station on which the project data is
located to the Ethernet interface of the CPU.
You will find more detailed information on loading in the following sections of the
STEP 7 online help:
•"Loading project data"

3.3 Connecting readers / serial devices
NOTICE
Correct usage
When connecting non-specified devices to the RF120C, it is possible that the connected
device may be destroyed.
A pre-assembled cable therefore permits the optimum and simple connection of the reader.
The standard version of the connecting cable is available in lengths 2 m, 5 m and 10 m.
Figure 3-2 Opening the doors in the housing of the RF120C
To connect the cable, open the lower door in the housing as shown in the figure and connect
the reader or serial device using the D-sub cable and the 9-pin D-sub socket of the
communications module.
NOTICE
Attaching strain relief
When a SIMATIC MV320 optical reader is connected to a communications module, you need
to secure the MV320 connecting cable with strain relief. This strain relief can be provided by
means of a cable clamp, for example. Secure the MV320 connecting cable by fixing the
cable to the rack between the D-sub connector and the cable curve of the MV320
connecting cable using the strain relief.

Power supply
The 3-pin socket for the external 24 VDC power supply is located on the top of the module.
The reader is supplied with voltage via this power supply. The matching plug with screw
terminals ships with the product. If there is overload, the RF120C turns off the power supply
to the reader and signals this to the CPU.
