Warning notice system
This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent
damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert
symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are
graded according to the degree of danger.
DANGER
indicates that death or severe personal injury will result if proper precautions are not taken.
WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NOTICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will
be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to
property damage.
Qualified Personnel
The product/system described in this documentation may be operated only by
personnel qualified
for the specific
task in accordance with the relevant documentation, in particular its warning notices and safety instructions.
Qualified personnel are those who, based on their training and experience, are capable of identifying risks and
avoiding potential hazards when working with these products/systems.

Note
Open source software
The product contains open source software. Read the license conditions for open source
software carefully before using the product.
The manual for the relevant product provides information on finding the license conditions.
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: (http://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.

Notes on the table
Notes on the columns:
●
Station type "Node station"
A node station is located in the plant hierarchy between the master station and other
lower-level stations. The module requires at least two interfaces.
In the configuration, the "network node type" of the interface connected to the master
station is configured as "Node station". See section Networking of the interfaces
(Page 38) for information on this.
●
STEP 7 product with S7-1200 CPs
S7-1200 CPs can be configured under STEP 7 Basic for connection to a third-party
master.
You need STEP 7 Professional project to connect the CPs to SIMATIC NET master or
node stations configured in STEP 7.
●
Firmware
The required firmware versions of the modules relate to the complete configuration
described in this manual. You can find the required STEP 7 version for this in the section
Software requirements (Page 15).
Modules with lower firmware versions can be configured in older STEP 7 versions with a
deviating scope of functions.
1.2
Configuration examples
Below, you will find several configuration examples with the communications modules that
can be used.
Communication via Ethernet / Internet, sending e-mails
In the sample configuration shown, S7 stations communicate with the master station via the
Ethernet interfaces of the different modules.
With their Ethernet interfaces, TIM modules enable connection to a redundant master
station.

Figure 1-1 Communication via Ethernet / Internet
E-mails
The modules can generate and send e-mails due to events. The following recipients are
possible:
●PCs with an Internet connection
●Cell phones
●SIMATIC stations with the appropriate program blocks
Inter-station communication
Direct inter-station communication between S7 stations with a TIM is possible via IP-based
networks.
Inter-station communication, in contrast, runs via a master station that forwards the frames to
the target subscriber.

Path redundancy using the serial interface
In the following example, the Ethernet interface and the serial interface are used with the
TIM 1531 IRC to set up redundant transmission paths.
●Ethernet interface for communication via Ethernet / Internet
●Serial interface for communication via a WAN network (dedicated line or dialup network)
Figure 1-2 Communication via redundant paths
Path redundancy is also possible over two Ethernet networks.

Connection resources
●
Telecontrol connections
The number of connections or communications partners is limited for the two interface
types and every individual interface.
Note that redundant connection paths of a connection between two partners require two
connection resources on each partner.
–Max. number of connections: 128
Distribution over 4 interfaces can take place in any way (max. 128 per interface).
●
E-mail
A connection to send e-mails can be established during runtime.
●
S7 connections
–Max. 4 connection resources for PG/OP connections (see below)
●
PG/OP connections
4 connection resources for connections to the engineering station or HMI devices
(included in the configuration limits of the S7 connections, see above)
●
PG routing
Max. 4 connections at the same time
●
Online functions
See PG/OP connections
●
HTTP/HTTPS
Max. 2 connections per Ethernet interface
Number of data points for the data point configuration
The maximum number of configurable data points is 3000.
Message memory: Send buffer / SD card
The TIM has a frame memory (send buffer) for the values of data points configured as an
event.
The send buffer has the following maximum size (number of events):
●250000
The size of the frame memory is divided equally among all configured communications
partners.

Note
Double the connection resources with direct communication between stations (only via
Ethernet or dial-up network)
Note that when there is direct communication between two stations, 2 connection
resources
are occupied per station: One for the master station connection, one for the station
connection.

The total number of 128 also applies to the TIM 4R IE DNP3 as a node station. The maximum number per interface is
obtained from the information in the "Master station" or "Station" rows.
Number of communications objects per TIM
The maximum number of communications objects for DNP3 communication per TIM is 100.

Size of the message memory for events
●TIM 3V-IE DNP3: 64 000 events
●TIM 4R-IE DNP3: 200 000 events
Number of S7 connections via Ethernet
In addition to the DNP3 connections, the number of possible S7 connections via the Ethernet
interface is as follows:
●
TIM 4R-IE DNP3
Number in total: Max. 5,
of which:
–2 configurable S7 connections
–2 PG connections
–1 OP connection
●
