To prevent unauthorized access, observe the following security recommendations when
working with the communication module and WBM (Web Based Management).
General
●Check regularly that the device complies with these recommendations and/or other
internal security policies.
●Evaluate your plant as a whole in terms of security. Use a cell protection concept with
suitable products.
●Do not connect the device directly to the Internet. Operate the device within a protected
network area.
Physical access
●Restrict physical access to the device to qualified personnel.
●Lock unused physical ports (e.g. Ethernet ports) on the device. Unused ports can be used
to access the system without authorization.
Software (security functions)
●Keep the software up to date. Keep yourself informed regularly about safety updates for
the product.
You can find information about this at Link: (https://www.siemens.com/industrialsecurity).
●Activate only protocols that you actually need to use the device.
●Limit access to the device using a firewall or rules in an access control list (ACL).

Firmware encryption
The firmware itself is signed and encrypted. This ensures that only authentic firmware can be
downloaded to the device.
Secure/non-secure protocols
●Check whether it is necessary to use SNMPv1. SNMPv1 is classified as non-secure.
Make use of the possibility to prevent write access. The product offers corresponding
settings for this.
●If SNMP is activated, change the community names. If unrestricted access is not
necessary, limit access via SNMP.
●Use secure protocols if access to the device is not protected by means of physical
safeguards.
The following protocols provide secure alternatives:
HTTP →HTTPS
●To prevent unauthorized access to the device or network, set up appropriate safeguards
against non-secure protocols.
●Enable only the services (protocols) that will actually be used on the device. The same
applies to the installed interfaces/ports. Unused ports could be used to access the
network downstream from the device.

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 constitute one element of such a concept.
Customers are responsible for preventing unauthorized access to their plants, systems,
machines and networks. Such systems, machines and components should only be
connected to an enterprise network or the internet if and to the extent such a connection is
necessary and only when appropriate security measures (e.g. firewalls and/or network
segmentation) are in place.
For additional information on industrial security measures that may be implemented, please
visit
Link: (https://www.siemens.com/industrialsecurity)
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends that product updates are applied as soon as they are
available and that the latest product versions are used. Use of product versions that are no
longer supported, and failure to apply the latest updates may increase customers’ exposure
to cyber threats.

3.1 Properties of the communications modules
Area of application
The SIMATIC RF185C, RF186C, RF188C, RF186CI and RF188CI communication modules
are designed for use in all areas of automation. It covers all areas in which SIMATIC Ident
RFID readers and optical readers are operated. Due to the large variety of interfaces -
PROFINET, EtherNet/IP, OPC UA, and XML - the application can run at the field level on an
S7/Rockwell controller, on a PC or at the IT level. This means diagnostic data, such as
processed transponder data or log entries, can be transferred to higher-level systems via
OPC UA or XML parallel to regular operation.
Figure 3-1 Communication modules SIMATIC RF185C, RF186C, RF188C as well as RF186CI and
RF188CI
Due to the high degree of protection, mounting without a protective enclosure is possible
directly near the RFID read points. The small mounting surface of the communication
module facilitates installation in confined spaces.
Two connections each for Ethernet and power supply allow configuration in a line structure in
addition to a star structure. The L-coded M12 connectors for the power supply allow a high
feed-through current in a line structure. The SIMATIC RF18xCI communication modules
have an additional I/O interface over which up to 8 inputs or outputs can be connected. In
addition to the familiar configuration types via TIA Portal and GSDML, these communication
modules also feature integrated Web Based Management (WBM), which enables devices to
be set via a standard browser. The WBM supports you during commissioning, diagnostics
and servicing. It also displays information about the connected readers and enables the
reading/writing of transponder data.

3.2 I/O functions of the CI device versions
Unlike the C device versions, the CI device versions SIMATIC RF186CI and RF188CI have
an I/O interface. You can use this interface either as a single digital input or output or for the
connection of an IO-Link module (e.g. IO-Link module K20).
The I/O interface can, for example, also be used as an alternative to the digital
inputs/outputs of the controller. One such application example is the configuration of
automatisms that are triggered by an event or changed status, for example, by a transponder
that was recognized. Unlike with the digital inputs/outputs of the S7 controller, the status is
changed by the event that occurs and remains in this status until a new event occurs. Note
that the reaction time of the digital outputs (and inputs) of the communication module
depends on the CM load and is 50 - 100 ms on average.
If the I/O interface is used for connecting an IO-Link module, the CM can use up to 8 digital
inputs/outputs of each of the modules. Only DI/DO modules with a maximum of 16 bits of
cyclic process data are supported (input and output data). Note that the SIMATIC RF200 IO-
Link Ident readers cannot be operated via SIMATIC RF186CI/RF188CI.
3.3 User-specific procedure
As described above, the communication modules are designed for different environments
and requirements.
If you operate the communication modules in an automation environment, they are
configured and programmed from the perspective of an S7 user. Integration in third-party
controllers (e.g. Rockwell controllers) is, of course, also possible. In this case, the
configuration, engineering, and programming is performed from the point of view of a
Rockwell user. If you operate the communication modules in an OPC UA or XML
environment, the configuration and programming are made from the perspective of an OPC
UA or XML user.
If you want to adapt the communication modules to your requirements, we recommend the
following user-specific procedure:
Procedure as S7 user
1. Connect the hardware
You can find information on this in the section "Connection (Page 27)".
2. Assign the IP address / device name
You can find information on this in the section "Assign the IP address / device name
(Page 47)".
3. Configure communication module
You will find information on this in the section "Configuration via PROFINET IO
(Page 52)" or "Configuring with the WBM (Page 61)".
4. Program reader commands
You can find information on this in the section "Programming via SIMATIC controller
(Page 111)".

Integration
The following figure shows an example of an RF188C connection to an automation system.
Figure 3-3 Configuration graphic RF188C
As of STEP 7 Basic / Professional V15.1, the RF18xC communication modules are
integrated into the TIA Portal; as of STEP 7 Basic / Professional V16, the RF18xCI
communication modules are integrated into the TIA Portal. Integration into older STEP 7
versions and third-party systems is performed via a GSDML file. The communication module
can then be configured via the TIA Portal or another engineering system. The GSDML file is
stored on the communication module and can be downloaded from it using a Web browser.
You can also find the GSDML file at the website of Siemens Industry Online Support.
