Applications
The CPU can use the DHCP communi-
cation protocol to assign the network
configuration via a DHCP server.
The CPU uses a client ID for identifi-
cation 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.
The MRP interconnection procedure
is an extension of MRP.
MRP interconnection enables the
redundant coupling of two or more
rings with MRP in PROFINET net-
works.
Additional methods to manage web
applications via Web API
You can use all available Web API
methods within the web application
Reading and changing the CPU oper-
ating state via Web API
Ticket methods for transferring large
amounts of data outside of the JSON
RPC protocol
Diagnostic information is available
for all technology objects
Improved display and grouping of the
tags
The feedback messages of the OPC
UA server with the "Application
Name" can be sent via DNS.
The NTP client of the CPU can address
its relevant NTP servers via DNS.
The Web server can be consistently
reached via DNS addressing. DNS is
taken into account during certificate
handling.
• Backlash compensation
• Linear motor
Customer benefits
With DHCP, you can integrate
the CPU into an existing IT
network without having to
make additional changes to
the PROFINET interface.
There is no limit to the maxi-
mum number of 50 devices in
a ring when setting up redun-
dant network topologies.
Monitoring of larger topolo-
gies 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
Comprehensive diagnostic
options by means of motion
control applications are possi-
ble via the web server.
A pool of NTP servers can be
addressed.
The repeat accuracy of a
movement is increased by
compensation for the mechan-
ical play of the real axis.
Easier control of highly dy-
namic linear motors.
