21 Time Adjustment
This chapter describes the different time adjustment features of the SMP Gateway.
21.1 Monitoring Time Information
The SMP Gateway offers multiple ways to monitor the time information and statuses:
Some system data points provide time information. They are all prefixed by “_smp___clock”
and are visible using the SMP Gateway’s web server (see “Using a Web Browser to View
Data in Real
Time”, page 59). For more information on system data points and an exhaustive
list o
f time-specific points, see “System Data Points”, page 231.
Current data and time can also be seen in SMP Stats, in the Vital System Information folder,
from the Internals folder located in the System folder. For more information on
SMP Gateway statistics, see “Information Provided by SMP Stats”, o
n page 56.
SMP 16’s time information is displayed on the gateway’s front panel, using the SYNC LED.
For a complete description of the different SYNC LED states, refer to the gateway’s
installation guide on the SMP Gateway Software & Tools CD-ROM.
Also for the SMP 16 model, more precise time information can be seen in SMP Stats, in the
Clock folder, from the Internals folder located in the System folder.
21.2 Setting SMP Gateway’s Internal Clock
The SMP Gateway has a real-time clock installed, with battery backup. It is set once during the
installation. If the clock does not indicate the accurate time or was not set right, you can change it
manually, using SMP Manager.
Note: If the SMP Gateway is synchronized by a GPS clock or any other external time
source, setting time manually will not work.
To set the SMP Gateway’s clock using SMP Manager:
Launch SMP Manager.
