GpSetEventSrq

$image\BLTLRGSQ.gif$ Boards that Support the Function $image\SETUP.gif$ $image\SANBTN.gif$

$image\head10.gif$ Operarion An event is generation according to receiving of SRQ.In order to make an event generation in fact, performance of GpSetEvent function is necessary.

$image\head10.gif$ Format

(VB.NET)

Dim hWnd As Integer

Dim wMsg As Short

Dim SrqOn, Ret As Integer

Ret = GpSetEventSrq(hWnd, wMsg, SrqOn)

(C)

HANDLE hWnd;

WORD wMsg;

DWORD SrqOn,Ret;

Ret = GpSetEventSrq(hWnd, wMsg, SrqOn);

(C#)

int hWnd;

ushort wMsg;

uint SrqOn, Ret;

Ret = gpib.SetEventSrq(hWnd, wMsg, SrqOn);

(Python)

hWnd = ctypes.wintypes.HANDLE()

wMsg = ctypes.c_ushort()

SrqOn, Ret = ctypes.c_ulong(), ctypes.c_ulong()

Ret.value = GpibPy.GpSetEventSrq(hWnd, wMsg, SrqOn)

$image\head10.gif$ Mode Master mode

$image\head10.gif$ Parameter hWnd : Specify the handle of the receiver of the conversion complete event message

wMsg : The discrimination message number which is used by generation event message is designated.

Designation possible range : 400H to 7FFFH

SrqOn : Designation of the event generation at the time when SRQ was received.

0 : Event is not generation.

1 : Event is generation

Ret : End information(Return value)

0 : Normal completion

80 : GpIni() hasn't execute

140 : Asynchronous function is executing now

255 : Parameter error

(See "Return Values" for details.)

$image\head10.gif$ Notes 1.When SRQ was received, this function appoints whether generation an event.In order generation an event in fact, execute of GpSetEvent function is necessary.Moreover, when an event of SRQ was made generation, in order to receive following event, SRQ by a slave needs to be missed at once.In order to make following event generation, performance of GpPoll function and GpEnableNextEvent function becomes indispensable.Please be careful.

2.By API-TOOL,even each series use this message.A using message number has been set up as follows.

SIO 410H to 42FH

GPIB 430H to 44FH

AIO 450H to 46FH

DIO 470H to 48FH

SMC 490H to 4AFH

CNT 4B0H to 4CFH

It is recommended by GPIB to use a value of 430H to 44FH.

3.Do not make a message number(GpSetEventDet function, GpSetEventDec function) please duplicate with the value which was set up in other event setting function.
