Setting the time in a CPU to the current time of your PG/PC
● Downloading a new program to a CPU or an HMI device
● Downloading from CPU, downloading to CPU or deleting rece data from a CPU
● Downloading from CPU or deleting data log data from a CPU
● Backup/restore of data from/to a backup file for CPUs and HMI devices
● Downloading service data from a CPU
● Reading the diagnostics buffer of a CPU
● Performing a CPU memory reset
● Resetting devices to factory settings
● Downloading a firmware update to a deviceyou 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. Thus, you 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 investment in the long term and optimal exploitation
of resources
3.11.5 PRONETA
With PRONETA (PROFINET network analysis), you analyze the plant 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 plant.
PRONETA connection via WLAN to SIMATIC and ET 200SP with, for example, the following
functions:
● Detect up to 50 networked CPUs via S and establish a connection
● Change CPU operating mode (RUN/STOP)
● Read out CPU diagnostics information and send via e-mail
● Monitor and modify variables and tags
● High security through encrypted communication and encrypted profile data; password to
start app and establish the connectionThe automation system/ET 200MP distributed I/O system consists of a single-row
configuration in which all modules are installed on one mounting rail. The modules are
connected by means of U connectors, and thus form a self-assembling backplane bus.
You can configure the automation system/ET 200MP distributed I/O system with
fail-safe and non-fail-safe modules.
4.1.1 Hardware configuration of the automation system
Maximum configuration
● The integrated system power supply of the CPU supplies 10 W or 12 W (depending on
CPU type) to the backplane bus. The power budget calculation determines the exact
number of modules (without optional PS) that can be operated with the CPU. The
operating princle is described in section Power balance calculation (Page 104).
● A maximum of three system power supplies (PS) is possible. one system power supply
(PS) can be inserted to the left of the CPU and two system power supplies (PS) can be
inserted to the right of the CPU.
