DioGetTriStateTerminationMode

GX5295, File.

Return the channel Tri-State termination mode.

DioGetTriStateTerminationMode (nHandle, nChannel, pnMode, pnStatus)

Name	Type	Comments
nHandle	SHORT	Master board handle, Board handle or File board handle.
nChannel	PSHORT	If Board Handle was passed: Channel number in the DIO board, each board has 32 I/O channels, I/O channels number range is 0-31. Each DIO board has 4 Auxiliary channels number range is 0-3. If Master Board Handle was supposed: Channel number in the DIO domain, each DIO board adds 32 I/O channels, I/O channels number range is 0-991 (1 master and 30 slaves). Each DIO board adds 4 Auxiliary channels, Auxiliary channels number range is 0-123 (1 master and 30 slaves).
pnMode	PSHORT	Returned Tri-State termination mode: 0 DIO_TRI_STATE_TERMINATION_MODE_DEFAULT: Default termination mode, in this mode the channel will be set to Hi-Z whenever the channel direction is set to input. 1 DIO_TRI_STATE_TERMINATION_MODE_LEVEL: in this mode the channel will be set to the voltage as specified in DioSetupTriStateTerminationVoltage API whenever the channel direction is set to input.
pnStatus	PSHORT	Returned status: 0 on success, negative number on failure.

GX5295:

The specified termination voltage is the same voltage that is used by the input active load commutating voltage.

Channels termination voltage can be read back and set dynamically at any time even while the DIO is running mode.

The following example returns the channel Tri-State termination mode for channel 0:

SHORT nMode;
