Comment: An accompanying text about the virtual channel. This text can be a detailed explanation of the
channel's name or may be used for any other purpose. The comment's maximum length is 255
characters.
Unit: A drop-down list box full of choices for the unit is presented. An arbitrarily set text, having up to 42
characters, can also be entered as the unit.
Sampling interval: The virtual channel's sampling rate, which results from the sampling rates of the
channel-function's parameter channels, is indicated. In addition to the parameter channels' sampling
rates, data reduction is also given consideration, if applicable.
On the Function page, you can specify how the virtual channel's values are computed. For this purpose, a
function formula is selected and parameterized.
Virtual Channel Properties dialog (Page 2)
Function: In the drop-down list, the available functions, ordered by function group, are offered (an
overview of the computational functions is to be found in the chapter 'Virtual Channels' ). A help text
about the function selected is presented.
Function parameters: In the boxes below the function selection box, the function parameters can be set.
A description of the function parameters can be found in the 'Functions Reference'.
The functions usually take one or two channels as their parameters. The channels can be physical
channels or other virtual channels. If two channels are specified as parameters they must have the same
sampling rate.
If the selected function's expression contains numerical constants or is combined in mathematical
operations with parameter channels, it is given in the parameter channel's units. The parameter
channel's scaling must be taken into account for the numerical constant.
The page Message mapping contains information on the data type, the position in the message and the
channel's scaling.
