Causes a specified GPIB device to switch into local mode of operation.
[ lStatus = ] GpibLocal ( lBoardDevice )
The GpibLocal procedure syntax has the following parts:
|
Name |
Type |
Description |
|
lStatus |
Long |
Status |
|
lBoardDevice |
Val Long |
Board to Device address |
This function causes the specified device to obey commands from its front panel control switches by performing the Go To Local GPIB function (GTL). If lBoardDevice specifies only a board address, the Remote Enable (REN) line is de-asserted, placing all devices connected in local mode.
The hexadecimal format of lBoardDevice should be as follows:
lBoardDevice = 0xBBPPSS
Where:
|
BB |
Board address (1 - 9) |
|
PP |
Device Primary address (0 - 31) - 0 if not used (bus address), 31 used for Primary address of 0 |
|
SS |
Device Secondary address (0 - 31) - 0 if not used (bus address or device without Secondary address), 31 used for Secondary address of 0 |
When PPSS is 0, lBoardDevice specifies a board address.
The value of lBoardDevice may be obtained using the GetDriverAddress function.
The function returns 0 on success and -1 on failure.
The following command sets an oscilloscope into local mode:
GpibLocal(GetDriverAddress("SCOPE"))
