● Updating the firmware of the CPU and connected modules
You can find the SIMATIC Automation Tool on the With PRONETA (PROFINET network analysis), you analyze the PROFINET
network during commissioning. PRONETA features two core functions:
● The topology overview independently scans PROFINET and all connected components.
● The IO check is a fast test of the wiring and the module configuration of a system.
You can find PRONETA on the his section lists the new features of the CPU with firmware version V2.0.
You can find additional information in the sections of this manual.
Table 2- 1 New functions of the CPU with firmware version 2.0 as compared to firmware version V1.8The PWM mode is used when an output module
is to control greatest possible outputs with
low power loss (heating, size).
You use pulse width modulation, for example,
to control:
• the temperature in a heating resistor
• the force of a coil in a proportional valve
and thus the position of a valve from
closed to completely open
• the speed of a motor from standstill to full
speed
With pulse width modulation, a signal with defined
cycle duration and variable on-load factor is
output at the digital output. The on-load factor is
the relationsh of the pulse duration to the cycle
duration. In PWM mode, you can control the onload
factor and the cycle duration.
With pulse width modulation, you vary the mean
value of the output voltage. Depending on the
connected load, you can control the load current
or the power with this.
Frequency output
mode
You can implement frequencies up to 100 kHz
and thus work in ranges that cannot be
reached by a CPU with a simple digital output
with a frequency up to 100 Hz.
You can generate frequencies very precisely.
The receiver can reconstruct the information
exactly when transmission conditions are less
than ideal.
In frequency output mode, you assign a frequency
value with high frequencies more precisely
than by using period duration (PWMData exchange is implemented between various
systems, both within the process level and
also with systems at the control and company
management level:
• To embedded systems with controllers
• To controllers with MES systems and systems
of the enterprise level (ERP, asset
systems)
• To controllers with controllers

rom other manufacturers
• To intelligent sensors with controllers
Supported standard: OPC Data Access, DA.
OPC UA is a uniform standard for data communication
and is independent of any particular operating
system platforms.
You have integrated safety mechanisms on various
automation systems, e.g. with data exchange,
at application level, for the legitimation of
the user.
OPC UA servers provide a wide range of data:
• Values of PLC tags that clients can access
• Data types of these PLC tags
• Information about the OPC UA server itself
and about the CPU
Clients can thus obtain an overview and read in
specific values.
PROFINET IO
MRPD: Media Redundancy
for Planned
Duplication for IRT
PROFINET IO IRT enables you to realize
applications that place particularly high demands
on the reliability and accuracy (isochronous
mode).
By sending the cyclic IO data in both directions in
the ring, the communication to the IO devices is
maintained even when the ring is interrupted and
does not result in device failure even with fast
