same interface is not supported! When attempting to activate them, both
servers are stopped and the diagnostic message 0xE989 or 0xE9AB is
output.
n
With an
OPC UA
project there is the possibility to configure an
OPC UA
server on
your CPU.
n
The configuration of an
OPC UA
project is only possible with the
SPEED7 Studio
V1.8.6 and up.
n
Since a
OPC UA
project is only executable by memory card, a memory card of VIPA
(VSD, VSC) must be plugged. Please note that you must always use a VSC card suit-
Chap. 4.16 ‘Deployment storage media - VSD, VSC’ page 111
n
If the memory card is removed for a short time, the SF LED gets on. This indicates
that a feature is missing and the
OPC UA
server will quit after 72 hours.
n
When the project is transferred from the
SPEED7 Studio
, the
OPC UA
project is auto-
matically transferred as TAR file to the inserted memory card.
n
The
OPC UA
server must be activated in the CPU.
n
The access is made with an OPC UA client via the
‘Endpoint URL’
of the corre-
sponding interface. The
‘Endpoint URL’
can be found on the
Device web page
of the
CPU.
