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

2.2 Parameter description
Smoothing
The individual measured values are smoothed by digital filtering. The smoothing can be
adjusted in four steps, in which the smoothing factor k multiplied with cycle time of the
electronic module equals the time constant of the smoothing filter. The greater the
smoothing, the greater the time constant of the filter.
The figure below shows the step response with the various smoothing factors in relation to
the number of subassembly cycles.

Interference frequency suppression
The 2AI U HF analog input module supports the setting of interference frequency
suppression (50 Hz or 60 Hz) on the interface module. This analog input module
(HIGH FEATURE) also enables the interference frequency suppression to be disabled; i.e.,
this setting will be ignored on the interface module. Disabling interference suppression
reduces the conversion and cycle times in this module.

Analog value representation 4
4.1 Introduction
Electronic modules with analog outputs
With the electronic module with analog inputs, continuously variable signals, such as those
occurring in temperature measurement and resistance measurement, can be acquired,
evaluated, and converted to digital values for further processing.
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.

Introduction
The following tables contain the digitized analog values for the measuring ranges of the

Since the binary representation of the analog values is always the same, these tables only
compare the measuring ranges with the units.

4.3 Effect on analog value representation
4.3.1 Effect of the supply voltage and the operating state on analog input values
The input and output values of the analog modules are dependent on the power supply for
electronics/sensors and on the operating state of the PLC (CPU of the DP master). This is
illustrated by the table below.

4.3.2 Effect of the value range on the 2AI U HF analog input
The way electronic modules respond to analog inputs depends on where the input values fall
within the value range. This is illustrated by the table below.
Table 4-6 Response of the analog modules, depending on where the analog input value falls within the range of values
Measured value within ... Input value in SIMATIC S7 format Input value in SIMATIC S5 format
Nominal range Measured value Measured value
Over-/underrange Measured value Measured value
Overflow 7FFFH End of the overshoot range +1 plus
overflow bit
Underflow 8000H End of the underrange -1 plus overflow
bit
Prior to parameter assignment, or
incorrect parameter assignment
