Hardware details

The Hardware details tab shows all the important information about your device, such as the serial number and MAC address, without having to look at the physical device. You can also change the device name and description on this tab. Click the Save button after you have changed the name or description of the device to apply the changes.

Clicking the Apply device button allows you to assign your devices to GridVis Web. This allows you to have your devices managed by GridVis Web. The service then takes over automatic actions such as reading out the devices. Once the devices have been assigned to GridVis Web, device actions can be carried out without starting GridVis Desktop.

Once you have selected a device, you will see the basic settings and the advanced settings. Enter the new connection data for your device and click the Connection test button to test the connection to your device. Finally, click the Save button to add the device with the updated connection information and manage it in GridVis Web.

Time & Readout

Use the Time & Readout tab to set the time synchronization of your devices and read out the data memory.

Time information and time synchronization

The Time information area shows the current system time, the current device time and any possible difference between the two times. Clicking the Synchronize device time button synchronizes the system time and the device time. The device time is adjusted to match the system time.

You can also configure time synchronization for your devices. Time synchronization can be carried out either via an NTP client or via the GridVis service.

• NTP client : You can provide an NTP server as a time source for all your devices. To do so, check the box next to  Activate NTP client and enter the address of the NTP server. You can specify several NTP servers, but you must separate the addresses with a semicolon. If a server cannot be reached, the next specified server address is queried.

• GridVis service : The device time can also be synchronized via the GridVis time. The GridVis time corresponds to the system time. Check the box next to Set time via the service (GridVis) and then select a Time point (time instant) at which the time is to be synchronized.
