To initiate an initial start or a restart of the central unit (PC linked to central unit) pro-
ceed as follows:
Click Device → Reset or click Device → Resume on the menu bar.
Activating an initial start or restart can be protected by the password for testing and
diagnostics. If you have activated this password you will be prompted to enter it be-
fore one of the two commands will be executed. A dialog box opens for this pur-
pose.
Enter the correct password in the box named Password and then click OK. If the
password is wrong, you will receive an error message. When the password is cor-
rect, the command will be executed.
6.3.7 Read and Set Date / Time
You have already decided in Chapter 4.6.2, page 75 on date and time management
whether to set the internal clock and which synchronization source to use.Usually, a
plausible time is already displayed during the device start. The time is either set auto-
matically by the connected synchronization source or manually. Until the synchroniza-
tion takes place and sets a valid time, different time displays may appear on the de-
vice. They are as follows:
The bay units are automatically synchronized via the central unit. For the operation wi-
thout a central unit, the time for the bay units can be set via DIGSI or via local opera-
tion.
Clock status Besides the display of date and time also the clock status is indicated. The text of the
status display may look as follows for regular states of the time management:
The identifiers of the clock status (“status bits”) have the following meaning:
Table 6-3 Clock status
No. Status text Status
1 -- -- -- --
synchronized
2 -- -- -- ST
3 -- -- ER--
not synchronized
4 -- -- ER ST
5 -- NS ER--
6 -- NS-- --
NS Not set Clock was not set manually or synchronized after start.
If the synchronization is performed via the system port, the
transferred time value is marked “invalid” but the cyclical
synchronization continues.
ER Error There is no cyclic synchronization at present within the scope of
the tolerance time (time may jump)
ST Daylight-saving
time
The synchronization time last received has delivered a daylight-
saving time bit (Central European Daylight-Saving Time)
