[2023-12-19] The latest version of PowerUSER is required to connect to new inverters. For more information see the below link:https://danfosseditron.zendesk.com/hc/en-gb/articles/5045659438877-EC-C1200-hardware-modifications-and-required-actions-due-to-it- |
The signal scope provides slow but very long log files for general recording of the inverter performance and operation. It has a sampling time of approx. 0.1 - 0.5 seconds per sample (2 - 10 Hz sample rate), and depending on the performance of the PC used, several hours of log files can be recorded.
Signal logging does not require a configuration before recording and displaying the signals; simply select the signals to be recorded, as shown in figure 1, from the signals tab by right-clicking and selecting Signal logging or by clicking on the circle in the Log column. Signals that are selected to the scope will have a yellow or yellow/orange circle in the Log column. After choosing the desired signals, switch to the signal scope view and press the green run button. Templates or presets of the most useful signals for each application type are preprogrammed in PowerUSER and can be added quickly and conveniently into the signal scope via the "Configure" button, see the article How to use signal scope templates in PowerUSER for more information.

The signal logging will continue until the inverter is shut down or the stop button is pushed in the PowerUSER interface. The recorded signals are shown in real time on the signal scope view, shown in figure 2.

The recorded signal can be zoomed in/out and the values of a specific moment in the recording can be shown by enabling the cursor from the right toolbar. A visualization toolbar for the Control limit word signal can be enabled by right-clicking the signal name on the bottom of the page, and selecting the show decode option, see the article Show the active limit status in PowerUSER signal scope (decode) for more information.
Recorded data can be saved to a file by clicking the save data button, and saved data files can be recalled for viewing by clicking load data.
