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.

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 only form one element of such a concept.
Customer is responsible to prevent unauthorized access to its plants, systems, machines
and networks. Systems, machines and components should only be connected to the
enterprise network or the internet if and to the extent necessary and with appropriate security
measures (e.g. use of firewalls and network segmentation) in place.
Additionally, Siemens’ guidance on appropriate security measures should be taken into
account. For more information about industrial security, please visit
(http://www.siemens.com/industrialsecurity).
Siemens’ products and solutions undergo continuous development to make them more
secure. Siemens strongly recommends to apply product updates as soon as available and to
always use 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.
To stay informed about product updates, subscribe to the Siemens Industrial Security RSS
Feed under (http://www.siemens.com/industrialsecurity).

Functions
2.2.1
Scalable measuring range
Introduction
The scalable measuring range is available for the temperature measuring ranges of thermal
resistors (RTD) standard and thermocouples (TC). The measuring ranges for voltage,
resistor and thermal resistor climatic are not supported.
Function
The scalable measuring range is a limited section of a measuring range supported by the
module.
It allows you to increase the resolution for a configurable section.
●The "Measuring range resolution" parameter determines the resolution to 2 or 3 decimal
places.
●The "Measuring range center" parameter determines the temperature over which the
scalable measuring range is symmetrically spanned.

14 Manual, 09/2016, A5E36647959-AB
Typical areas of applications
Temperature measurements and temperature controls with high resolution save energy and
are required for:
●Manufacturing of special glass
●Manufacturing of semiconductors
●Heat processes / heat treatment in metals for the aerospace industry.

To obtain the absolute temperature, the measuring range center in the user program (as
offset) must be calculated with the value of the user data of the scalable measuring range.
The measuring range center is always output in the user data as the value "0". The user data
is correspondingly mapped to the bipolar input ranges in S7 format. Underflow/overflow is
also formed in accordance with the limits of S7.
Rules
●The measuring range center must be within the nominal range of the underlying
measuring range. It is specified in integers.
●The scalable measuring range is spanned symmetrically over the measuring range
center. Depending on the resolution, different value ranges result.
●The scalable measuring range is limited by underflow and overflow of the underlying
measuring range:
If the low limit is violated, the scaled measuring range is cut off at the underflow.
If the high limit is violated, the scaled measuring range is cut off at the overflow.
