NC channel
A TwinCAT NC configuration has at least one, but possibly also several channels. When selecting the SAF Task entry in the tree view, an axis channel can be added using the context menu described below.
Context menu:

Add channel
Adds another axis channel to the configuration. More detailed explanations can be found at Add NC-channel.
Delete
Removes the currently selected channel from the configuration.
Import channel
Imports a previously exported channel configuration (extension *.tce) into the current NC configuration.
"General" tab
With the entry "Axes" an axis channel is automatically created below the NC process image. If you select the corresponding option in the tree view, as shown in the following figure, the dialog "General" for the object is displayed on the right side. Furthermore, an online dialog is available for the axis channel.
