8 Menu Functions and Toolbar

8.5.8 Synchronizing the Device Time
This function is only available for devices that support synchronization (e.g.
the paperless recorder LOGOSCREEN es/cf).
Synchronization is only possible if the time difference between the PC and the
device is not greater than 30 seconds.
System requirements means that synchronization is only effective for
differences >1 second. The residual error is <±1 second. After long periods of
connected operation (e.g. when using the Ethernet interface) the deviation can
rise to 2 seconds.
8.5.9 Changing the Device Password
This function is only available for devices that have user/password
management (e.g. the paperless recorder LOGOSCREEN es/cf).
This function provides the option for altering the password at the device itself
or via the interface – because of the remote location of the device or as a
convenient method that does not require detailed knowledge of operation.
H
The function is useful if the device is operated at a remote location,
via Ethernet or a modem, or the user does not otherwise have
adequate knowledge of the system.
