Figure 17: ENVIS.Daq - configuration of date and time options.
2.5.2
Date and time (fig. 17)
This tab contains configurations related to the instrument internal time and date settings.
Warning ! manipulation with the time configuration erases all instrument archives and related
registers.
Instrument Time
panel displays actual time and date in the instrument and an absolute difference to the
actual time in PC. When this tab is opened for the first time the instrument time is immediately read and is
periodically actualized. Button
Refresh
rereads the instrument time again.
Time Setup
panel provides controls for actual modification of the time in instrument.
Set Time from PC
— sets the instrument time according to the clock in PC
Set user Time
— sets the instrument time to the manually given value
Adjust Time
— aligns the instrument time to the PC time without erasing instrument memory. Adjustment
to the desired value is achieved in a way that:
–
to move time forwards it skips required number of archives
–
to move time backwards it waits with the creation of next archive until the instrument reaches the
time given in setup.
Calendar Configuration
defines ways of interpretation and display of time tags in instrument and in its archives:
Synchronization
— defines how each instrument synchronizes its time. Methods supported include:
–
pulse per second and pulse per minute (PPS, PPM) on a digital input,
–
NMEA protocol on a communication line - the comm port must be configured,
–
NTP protocol over Ethernet - IP address of the time server must be filled
–
and a network frequency lock.
–
It is also possible to disable this function.
