GpibSendIFC

Function

Transmits the line (IFC) that makes talker/listener/controller state of all devices to initial state.

Format

Ret = GpibSendIFC ( Id, IfcTime )

Parameter

Id [ VB.NET: Short ][ C, C++: short ][ C#: short ]

Specifies DevID or EqpID.

Whichever it specifies, operation does not change.

IfcTime [ VB.NET: Short ][ C, C++: short ][ C#: short ]

Sets the time for transmitting IFC.

1 to 255

Time for transmitting IFC (value * 100[usec])

Return Value

Ret [ VB.NET: Integer ][ C, C++: long ][ C#: int ]

0	Normality completion
10001	Invalid ID was specified
10002	Driver can not be called
10552	The value of IfcTime is outside the designated range
20573	When it was not a master (controller), communication accompanied by address was performed.

Initial Value

None

Remarks

Usually it is no problem to set value of IfcTime to 1.

It does the same work as transmitting UNL or UNT when not changing state of controller.

When changing state of controller, devices except master (system controller) become slave (non-controller) state.

Please use GpibSendDeviceClear function to set slave device to initial state (when power is supplied).

Example

Transmits IFC in 1 usec.

C	short IfcTime; IfcTime = 1; Ret = GpibSendIFC ( Id, IfcTime );
