Process interfacing via an automation system (PLC, PC)
9.7 Remote client
Note
Keep "XML Backup" file safe
The "XML Backup" file contains sensitive data (password hash). For security reasons, keep
the "XML Backup" file in a safe place.
In order to be able to use these functions, an IP address for the remote client must be stored
in the WBM (Settings > Communication > Interfaces > Archiving/MMI).
The "XML Backup" and "XML Restore" functions each have their own HTTP requests. After
the reader has received one of these HTTP requests, if the requirements have been met, the
following tasks are first performed in both cases:
1. The connection to the WBM is terminated.
While the HTTP request is being processed by the optical reader, you can only open the
WBM in READ ONLY mode.
2. The optical reader changes to "Stop" mode.
3. The IN_OP bit is set to "0".
9.7.2

Once the optical reader has sent the HTTP response, the "IN_OP" bit is set and access via
the WBM is permitted again.
