Time - Anybus CompactCom 40 Network Manual

OPC UA
10.5

Time

An OPC UA server needs a mechanism for knowing the current UTC time and facilities to convert
to and from local time. The Anybus CompactCom will fetch the time from the network by
cyclically sending a request to a OPC UA Discovery Server. The server will be polled every 60
seconds with a timeout of 5 seconds. To configure the address of the Discovery Server, set
Network Configuration Object (04h), instance #41, attribute #5 with the URL of the Discovery
Server.
10.6 Authorization
Access is controlled by placing a file called opcua.cfg in the root directory of the file system of
the Anybus CompactCom. This file shall contain a list of users that are allowed OPC UA protocol
access using the Anybus CompactCom.
File Format:
Username1:Password1
Username2:Password2
...
UsernameN:PasswordN
The list of approved users can optionally be redirected to one or several other files.
If the list of approved users is put in another file, be aware that this file can be accessed and read from
the network.
In the following example, the list of approved users will be loaded from here.cfg and too.cfg.
[File path]
\i\put\some\over\here.cfg
\i\actually\put\some\of\it\here\too.cfg
