Repeated Capabilities

Repeated capabilities attributes are used to set the channel_string parameter to the underlying driver function call. This can be the actual function based on the Session method being called, or it can be the appropriate Get/Set Attribute function, such as niSwitch_SetAttributeViInt32().

Repeated capabilities attributes use the indexing operator [] to indicate the repeated capabilities. The parameter can be a string, list, tuple, or slice (range). Each element of those can be a string or an integer. If it is a string, you can indicate a range using the same format as the driver: ‘0-2’ or ‘0:2’

Some repeated capabilities use a prefix before the number and this is optional


session.channels['0-2'].channel_enabled = True

passes a string of ‘0, 1, 2’ to the set attribute function.
