Access to the OPC UA server

The OPC UA server integrated in SIRIUS 3RW44 soft starter PROFINET makes available
the following structured objects in its address space. The client has read access and, in
some cases, write access to these objects.
The following requirements must be met for write access:
● A secured connection with security policy "Basic128Rsa15" and message security mode
"SignAndEncrypt" and
● "OPC UA Server control function" check box is selected
The representation of the OPC UA variables depends on the OPC UA client used. Below you

You can find a detailed description of the individual variables in section OPC UA variables
(Page 104).
