--- The device info page.
--- The maintenance page. The configuration parameters from this page are described below.The Logger logical device watches an arbitrary parameter and, writes a message to the event log every time the parameter value changes. The message written to the log contains a user definable text and the new parameter value.
The Logger device may be used to journalize any type of parameter, however, fluctuating values like power measurements will produce a huge amount of data. Typical applications for the Logger device are to monitor position changes of signal switches, carrier on/off states or frequency settings.
Device window pages
The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .
--- The device info page. --- The maintenance page. The configuration parameters from this page are described below.Configuration parameters
At the maintenance page of the device window there are a couple of configuration parameter which must be set to interconnect the Logger device with the devices that will perform the frequency setting.
| parameter | description |
|---|---|
| messageId | Enter the message identifier here of the parameter the logger device shall listen to, e.g. "MODULATOR.tx.on". |
| text | Enter the message text which shall be written to the event log if the watched parameter changes. For example, "Modulator output switched" results to a log message "Modulator output switched ON" or "Modulator output switched OFF", depending of the new value of the parameter. |
