The “Channel Status Updates” window displays the operating mode that the VM40C
transmits once after startup. Furthermore you will find the last warning and alarm
events with timestamp. Figure 27 shows an example.

The graphs headed with “Field ...” show the data of the fields 1 to 6 (cf. page 10).
By clicking on     you can label and scale the axes and change the style of the
graphs. 
By clicking on “MATLAB Visualization” you can create additional visualizations.
Various templates are available for this purpose.

After selecting the template, you can create the desired visualization in the MAT-
LAB scripting language. The following script example generates a diagram with the
curves of the amplitudes X/Y/Z and the frequency according to the example in Fig-
ure 26 on the basis of the template “2-D line plots with y-axes on both left and right
side”.
To connect the script with the data of your measuring channel you only need to enter
the channel ID for x...x and the Read API key for y...y. Both can be found in the
“Private View” of your channel.

Note: A battery charge value of 110 % indicates that the battery is being charged.
