When using the Set Property functions in either LabVIEW or C, some of the available properties apply to the CAN interface and not a specific channel. Whenever you attempt to set an interface property after the port interface has already been started you will receive this error.
For example, if you try to set any of the Interface
properties in a loop you will see this error since the port is already running. Make sure that you set the Interface
properties outside of your loops to avoid this error.
This interface is usually configured to Start On Open. This option can be disabled.
