PCAN Handle Definitions

The PCAN_NONEBUS is a value used as default channel value. It is used for general purposes as using and configuring the Log capabilities of the PCAN-Basic API. It can also be used to remove all channel connections made by an application. 

These definitions are constants values in an object oriented environment (Delphi, .NET Framework) and declared as defines in C++ (plain API). 

Hardware Type and Channels: 

Not Plug & Play: The hardware channels of this kind are used as registered. This mean, for example, it is allowed to register the PCAN_ISABUS3 without having registered PCAN_ISA1 and PCAN_ISA2. It is a decision of each user, how to associate a PCAN-Channel (logical part) and a port/interrupt pair (physical part). 

Plug & Play: For hardware handles of PCI, USB and PC-Card, the availability of the channels is determined by the count of hardware connected to a computer in a given moment, in conjunction with their internal handle. This mean, that having four PCAN-USB connected to a computer will let the user to connect the channels PCAN_USBBUS1 to PCAN_USBBUS4. The association of each channel with a hardware is managed internally using the handle of a hardware. 

Python: 

The definitions of these values have the following form: TPCANHandle(handle) where handle is the value contained in the column with the same name. e.g. PCAN_PCCBUS1 is defined as TPCANHandle(0x61).
