New functions

This section contains an overview of the most important new firmware functions of the CPU
compared with the predecessor version CPU (V3.0).

CPU 1513-1 PN (6ES7513-1AM03-0AB0)
Equipment Manual, 11/2023, A5E40881673-AD
Applications
The CPU stores syslog messages in a local
cache (temporary memory).
The messages can be forwarded to a syslog
server.
As of TIA Portal version V19 and FW version
V3.1, the CPUs feature improved management
of users, roles, and CPU function rights (User
Management & Access Control, UMAC).
Starting with the above mentioned version,
you can manage all project users with their
rights (e.g. access rights) for all CPUs in the
project. You can do this in the editor for users
and roles in the TIA Portal.
As of V19, STEP 7 offers extended configura-
tion options for the SNMP and DCP protocols
in order to meet the requirements for
PROFINET Security Class 1.
As of STEP7 V19, a shared device/shared I-
device together with a maximum of two IO
controllers can be created in a single project.
Previously, the second IO controller required
its own project.
When network loads are high, timeouts may
occur in PROFINET IO devices during data
record communication. Previously, the
PROFINET IO communication was reduced by
the CPU in this case.
As of STEP 7 V19 and FW version V3.1, you
can configure the behavior of the respective
PROFINET interface.
Many new API methods extend your access
options to the CPU via the Web API.
Customer benefits
The syslog server saves all syslog messag-
es from its connected devices. The mes-
sages can be displayed on the interface of
the server and potential security risks can
be identified.
Project users can be managed via the TIA
Portal with their rights (for example,
access rights) for all CPUs in the project in
the editor for users and roles.
Additional protection of communication
within your PROFINET network.
Simpler configuration.
PROFINET IO communication is main-
tained even under high grid loads
