2.5.13 IMx-8/IMx-8Plus Stand-alone mode
The IMx-8/IMx-8Plus can be configured to be used in stand-alone mode. In this
scenario, a connection to the @ptitude Observer Monitor Service is not required as
data is not transferred for trending and analysis by the @ptitude Observer Client.
Instead, measurement data and alarms are displayed in the SKF Multilog IMx
Manager app.
Help on using the various functionality of the SKF Multilog IMx Manager app. Is
available in-app.
2.5.14 Time synchronisation
Each IMx-8/IMx-8Plus device has a backup power capacitor which will maintain the
time setting for approximately one week if the device is disconnected from power.
To correct or set/reset the time, use one of the following methods:
•
Automatic time synchronisation
This method is preferable since the IMx will continuously synchronise the
time with the computer that has @ptitude Observer Monitor Service running.
IMx devices use a standard (S)NTP time synchronisation protocol supported
by the Windows Time service.
To activate time synchronisation, refer to the Time Synchronisation chapter in
the "@ptitude Observer Installation Manual".
•
Set time manually
Use the "Set time" function in @ptitude Observer which is found under the
menu item "On-line", then "IMx/MasCon devices".
For IMx devices in stand-alone mode, the IMx Manager app will check and
update the time to the time on the mobile device being used, whenever it
connects.
2.5.15 Network data transfer
In operation, the IMx-8/IMx-8Plus is continuously monitoring the incoming sensor
signals and, where available, can have access to GPS data and measurements
shared by other systems via Modbus. It is connected to an @ptitude Observer
Monitor Service and data is stored in that remote database as specified by
predefined operating and storage conditions. These can include:
•
Trend and dynamic data stored at fixed time intervals.
•
Modified storage intervals while the measurement point is in alarm
or based on detected differences between the last two measurements.
The amount of the data transferred across the network is normally small but is
dependent on the configuration of the IMx. In case of temporary loss of the network
connection, data is still measured and stored locally so that when the connection is
re-established, collected data is transferred to the database.
