Description
function is therefore suitable for monitoring highly
dynamic processes.
The trace recording can also be displayed through the
Web server.
With OPC UA, data is exchanged via an open and vendor-
neutral communication protocol.
The CPU can act as OPC UA server. The CPU can commu­
nicate with OPC UA clients as an OPC UA server.
In turn, the CPU can access an OPC UA server as OPC UA
client, allow the OPC UA server to run methods and read
out information from the OPC UA server.
Through OPC UA Companion Specification, methods can
be specified in a uniform and vendor-neutral way. The
specified methods enable you to integrate devices from a
wide range of manufacturers into your plants and pro­
duction processes more easily.
You can use configuration control to operate different
real hardware configurations with a configured maxim­
um configuration of the hardware. This means especially
in series machine manufacturing you have the option of
operating/configuring different configuration variants of
a machine with a single project.
RT prioritizes PROFINET IO frames over standard frames.
This ensures the required determinism in the automation
technology. In this process, the data is transferred via pri­
oritized Ethernet frames.
for IRT data. The reserved bandwidth ensures that the IRT
data can be transmitted in time-synchronized intervals,
unaffected by other high network loads (e.g. TCP/IP com­
munication or additional real time communication).
Update times with maximum determinism can be real­
ized through IRT. Isochronous applications are possible
with IRT.
The Isochronous mode system property records meas­
ured values and process data and processes the signals in
a fixed system clock. Isochronous mode contributes to
high control quality and hence to greater manufacturing
precision. Isochronous mode reduces possible fluctu­
ations of the process reaction times to a minimum. Time-
assured processing makes higher machine cycles pos­
sible.
It is possible to establish redundant networks via the
Media Redundancy Protocol. Redundant transmission
links (ring topology) ensure that an alternative commu­
nication path is made available if a transmission link fails.
The PROFINET devices that are part of this redundant net­
work form an MRP domain.
RT operation is possible with the use of MRP.
