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 can be implemented, please
visit (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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed visit (https://www.siemens.com/industrialsecurity).

TIA Selection Tool
With the TIA Selection Tool, you can select, configure and order devices for Totally
Integrated Automation (TIA).
This tool is the successor of the SIMATIC Selection Tool and combines the known
configurators for automation technology into one tool.
With the TIA Selection Tool, you can generate a complete order list from your product
selection or product configuration.
You can find the TIA Selection Tool on the Internet
(http://w3.siemens.com/mcms/topics/en/simatic/tia-selection-tool).
SIMATIC Automation Tool
You can use the SIMATIC Automation Tool to run commissioning and maintenance activities
simultaneously on various SIMATIC S7 stations as a bulk operation independently of the TIA
Portal.
The SIMATIC Automation Tool provides a multitude of functions:
●Scanning of a PROFINET/Ethernet network and identification of all connected CPUs
●Address assignment (IP, subnet, gateway) and station name (PROFINET device) to a
CPU
●Transfer of the data and the programming device/PC time converted to UTC time to the
module
●Program download to CPU

SINETPLAN
SINETPLAN, the Siemens Network Planner, supports you in planning automation systems
and networks based on PROFINET. The tool facilitates professional and predictive
dimensioning of your PROFINET installation as early as in the planning stage. In addition,
SINETPLAN supports you during network optimization and helps you to exploit network
resources optimally and to plan reserves. This helps to prevent problems in commissioning
or failures during productive operation even in advance of a planned operation. This
increases the availability of the production plant and helps improve operational safety.
The advantages at a glance
●Network optimization thanks to port-specific calculation of the network load
●Increased production availability thanks to online scan and verification of existing systems
●Transparency before commissioning through importing and simulation of existing STEP 7
projects
●Efficiency through securing existing investments in the long term and optimal exploitation
of resources
You can find SINETPLAN on the Internet (https://www.siemens.com/sinetplan).

Replacement of an AI 4xRTD/TC 2-/3-/4-wire HF (6ES7134-6JD00-0CA1)
With an AI 4xTC HS (6ES7134-6JD00-0DA1), you can replace an AI 4xRTD/TC 2-/3-/4-wire
HF (6ES7134-6JD00-0CA1), that is configured for the "Thermocouple" or "Voltage"
measuring ranges.
You do not have to perform new configuration or new wiring. The "Outlier suppression"
function is enabled. You can find additional information on outlier suppression in the section

Due to the limited number of parameters at a maximum of 244 bytes per ET 200SP station with a PROFIBUS GSD
configuration, the parameter assignment options are restricted. If required, you can still assign these parameters using
data record 128 as described in the "GSD file PROFINET IO" column (see table above). The parameter length of the I/O
module is 13 bytes.
2
Only for configuration with PROFIBUS GSD file: The set reference junction is used with the additional parameter "Kx
Reference junction activated" in the case of "Enable". In the case of "Disable", no "fixed reference temperature" is used
for TC.
3
Interference frequency suppression: Noise at 400 Hz is automatically included in the filtering at 50 Hz.
4
Thermocouple types B and C are not suitable for reference junction temperatures below 0 °C on account of their defined
characteristic curve as of 0 °C.
5Only for REAL representation.
Note
Unused channels
"Deactivate" unused channels in the parameter assignment to improve the cycle time of the
module.
A disabled channel always returns the value 7FFF
H(REAL representation: 7F800000H).

4.3 Explanation of parameters
Diagnostics: Missing supply voltage L+
Enabling of the diagnostics for missing or insufficient supply voltage L+.
Diagnostics: Reference junction
Enabling of the reference junction diagnostics if the reference temperature of the reference
junction needs to be determined for the TC channel being operated.
Reference junction using the PROFINET GSD file
As reference junction for the TC measurement, a BaseUnit with internal temperature sensor
(BU..T) or the reference channel of the group 0, 1, 2, 3 can be used.
A possible parameter assignment is represented below:
Table 4- 3 TC channel
Setting
Description
Internal reference junction The reference junction temperature is read by an internal tempera-
ture sensor on the BaseUnit. Diagnostics: Reference junction is
triggered if there is an incorrect BaseUnit type.
Reference channel of group 0,
1, 2, 3
The channel acts as a
receiver
for the reference junction tempera-
ture of a group.
Fixed reference temperature The reference temperature of the thermocouple is set to 0 °C. As a
result, no temperature compensation is performed.
Note
Shared Device and "Reference channel of group 0, 1, 2, 3"
If the transmitter and receiver for the reference junction temperature of a
group
are assigned
to different IO controllers, then both IO controllers must be performing data exchange with
the IO device to ensure error
-free operation of the temperature compensation.
