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
update times. You achieve higher reliability than
with MRP.
Limitation of the data
infeed into the network
You limit the network load for standard Ethernet
communication to a maximum value.
They flatten peaks in the data feed.
You share the remaining bandwidth based on
demand.
Display and Web server
Backing up and restoring
via the display
You can back up and restore the CPU configuration
to/from the SIMATIC memory card without
a programming device/PC.
You can make a backup copy of an operational
project without STEP 7 (TIA Portal).
In an "emergency", you can simply use an existing
configuration without STEP 7 (TIA Portal), for
example, during commissioning or after a program
download.
Backing up and restoring
via the Web
server
Among other things, you can backup and
restore the configuration of the CPU to the
PG/PC on which the Web server is running.
Display and Web
server provide up to
three project languages
for comments
and message texts
When you export your plants worldwide, for
example, comments or message texts can be
stored on the card in up to 3 languages. For
example, German - the language of the author,
English - readable internationally, Portuguese
- language of the end user.
You provide customers with better service.
Trace via Web server When you enable trace functions via the Web
server, you have better service support. You
can send your trace recordings to your service
partner via Web service, for example.
You receive plant/project information for diagnostics
and maintenance requirements without
STEP 7 (TIA Portal).
You can provide trace recordings for each Web
server.

You save time in troubleshooting.
Monitoring of configured
technology objects
via a Web server
You can monitor states, errors, technological
alarms and the current values of technology
objects with the Web server.
Formatting, erasing or
converting a SIMATIC
memory card via the
display
Without the method using STEP 7 (TIA Portal), your SIMATIC memory card is formatted, deleted
or converted into a program card directly via the display. You save time.Greater number of
axes for Motion Control
applications and
new technology objects:
Output cam,
cam track and probe
Speed specification for, for example:
• Pumps, fans, mixers
• Conveyor belts
• Auxiliary drives
positioning tasks, such as:
• Lifting and vertical conveyors
• Feeding and gate control
• Palletizing equipment
Output cams and cam tracks make other applications
possible, for example:
• Glue lines application
• Triggering switching operations with precise
positioning
• Pin-point processing of products on a conveyor
belt
Probe operation, e.g.:
• For measuring products
• For detecting the position of the product on
a conveyor belt
You can implement additional Motion Control
