New functions Applications
OPC UA server You realize the data communication between
different systems, both within the process level
and on the control and enterprise levels:
•
•
•
•
Supported standard: OPC Data Access, DA.
PROFINET IO
PROFINET IO on the You can operate another PROFINET IO sys-
2nd PROFINET inter- tem on the CPU or connect additional IO de-
face vices.
MRPD: Media Re- PROFINET IO IRT enables you to realize
dundancy for Planned applications that place particularly high de-
Duplication for IRT mands on failure safety and accuracy (isoch-
ronous).
PROFINET perfor- You can develop applications with high de-
mance upgrade mands on speed and clock cycles. This is
interesting for applications with high demands
on performance.
Limitation of the data You limit the network load for standard Ether-
infeed into the net- net communication to a maximum value.

Customer benefits
OPC UA is a unified standard for data communi-
cation and is independent of any particular oper-
ating system platforms.
You have integrated security mechanisms on
different automation systems, for example, for
data exchange, on the application level, for au-
thentication of the user.
OPC UA servers provide a large amount of data:
Values of PLC tags that clients can access
•
Data types of these PLC tags
•
Information about the OPC UA server itself
•
and the CPU
In this way, clients can gain an overview and can
read and write values.
You use a fieldbus in the plant.
The CPU can perform fast and deterministic data
exchange as an I-device with a higher-level con-
troller (PROFINET/Ethernet) through the second
line.
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 failure safety
than with MRP.
Better utilization of the bandwidth results in short
reaction times.
You smooth peaks in the data infeed.
You share the remaining bandwidth based on
requirements.
