New functions Applications
DHCP (Dynamic The CPU can use the DHCP com-
Host Configura- munication protocol to assign the
tion Protocol) network configuration via a DHCP
server. The CPU uses a client ID for
identification on the DHCP server.
The following parameters can be
obtained:
• IP Suite
• DNS server
• NTP server
The CPU can also send its host
name to the DHCP server.
MRP interconnec- The MRP interconnection proce-
tion in PROFINET dure is an extension of MRP.
networks
MRP interconnection enables the
redundant coupling of two or more
rings with MRP in PROFINET net-
works.

Customer benefits
With DHCP, you can integrate the
CPU into an existing IT network
without having to make additional
changes to the PROFINET interface.
The limit of maximum 50 devices in a
ring does not apply when setting up
redundant network topologies.
Monitoring larger topologies with
ring redundancy
Web applications are also available in
STOP mode of the CPU
Reduced development times of web
server user pages
Additional applications for the web
server
More comprehensive diagnostic
options are possible via the web
server for motion control applica-
tions.
A pool of NTP servers can be ad-
dressed.
The repeat accuracy of a movement
is increased by compensation for the
mechanical play of the real axis.
Easier control of highly dynamic
linear motors.
