Safety Guidelines
Safety Guidelines
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
with a safety alert symbol, indicates that minor personal injury can result if proper precautions are not taken.
CAUTION
without a safety alert symbol, indicates that property damage can result if proper precautions are not taken.
NOTICE
indicates that an unintended result or situation can occur if the corresponding information is not taken into
account.
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 device/system may only be set up and used in conjunction with this documentation. Commissioning and
operation of a device/system may only be performed by qualified personnel. Within the context of the safety notes

Analog value representation 4
4.1 Introduction
Electronic modules with analog outputs
With the electronic modules with analog outputs, digital values set by a controller can be
converted to a corresponding analog signal (current) in an analog output module and used to
control suitable actuators (setpoint input for speed controllers, temperature controllers and
similar).
4.2 Analog value representation for measuring range with SIMATIC S7
Analog value representation
With the same nominal range, the digitized analog value is the same for input and output
values. Analog values are represented in two's complement.
The following table shows the analog value representation of the analog electronic modules.

4.4.1 Effect of the supply voltage and the operating state on analog output values
The output values of the analog modules are dependent on the supply voltage for
electronics/encoders and on the operating state of the PLC (CPU of the DP master). This is
illustrated by the table below.

The way electronic modules respond to analog outputs depends on where the output values
fall within the value range. This is illustrated by the table below.

Connecting 5
5.1 Connecting analog outputs
Introduction
This chapter describes the factors to consider when connecting the analog outputs.
Cables for analog signals
You should use shielded and twisted-pair cables for the analog signals. This reduces the
effect of interference. You should ground the shield of the analog cables at both ends. If
there are differences in potential between the cable ends, an equipotential bonding current
that may interfere with the analog signals will flow across the shield. In this case, you should
only ground the shield at one end of the cable.
Analog output modules
In the case of the analog output modules there is generally galvanic isolation
● Between logic and backplane bus.
● Between the load voltage and MANA.
