Now the program start has to be done with
formally although there’s no program still yet. Using “Start
Recording“
the process data value of the oversampling PDO “L1 Voltage Samples “ via the linked PLC
array variable can be recorded time dependent now.
As an example a sine wave input measurement value (204.5 Hz) will be illustrated below:
Fig. 150: Example of recording a sine signal with 10 x oversampling at 1 ms measurement cycle time
The X-axis view was fitted properly by using “Panning X”
after the recording was stopped
.
Following the “Chart” property “Use X-Axis SubGrid” was set to true with 10 divisions as well as the
“ChannelNodeProperties” attribute “Marks” was set to “On” with the colors “Line Color” blue and “Mark Color”
red. Therefore the latter indicates that 10 oversampling measurement points by the red marks.
Proceeding with / via ADS alternatively
In former TwinCAT 3 versions (or a lower revision as specified in the
above) the oversampling
PDO of the respective oversampling able terminal/box can be made visible for the ScopeView by activation
of the ADS server.
