Remote client
The remote client interface is an HTTP-based interface. The remote client can trigger
functions using HTTP requests sent to the optical reader. To make this possible, you need to
configure an IP address in the WBM that corresponds to the address of the client. The
optical reader only processes the HTTP requests that have the configured IP address as the
sender.
9.7.1
XML backup and XML restore
Note
Do not control at the same time via the control interface
Ensure throughout the entire automation process that nothing is controlled via the control
interface while the XML Backup and XML Restore functions are running. If control is
performed via the control interface, by setting the DISA bit for example, the "XML Backup"
and "XML Restore" functions cannot be executed.
Note
Backing up the diagnostic images before execution of the "XML Backup" and "XML Restore"
functions
Executing the "XML Backup" and "XML Restore" functions may delete any diagnostics
images in the optical reader memory.
If required, save the diagnostic images before you execute one of these functions.
