Chapter 4 GPIB 488.2 Library Reference
EnableLocal
Places specified devices in local mode (Can be "programmed" from front panel controls.).
Syntax
C EnableLocal(int board, short addresslist[])
Parameters
board
is an integer which identifies the GPIB board to be used for this operation. In most applications, this value is 0.
addresslist
is an array of GPIB addresses, terminated by the value
NOADDR
. These addresses identify the devices to enable locally.
Returns
ibsta
will contain a 16-bit status word as described in Appendix B,
IBSTA
.
iberr
will contain an error code, if an error occurred.
Usage Notes
When this routine is executed, the Controller addresses the specified GPIB devices as listeners and then sends the GPIB
Go To Local
(GTL) command.
To put all devices in local mode, use an array containing only the
NOADDR
value. This unasserts the GPIB
Remote Enable
(REN) line, thereby placing all GPIB devices in local mode.
Example
Put the GPIB devices at addresses 6 and 7 (connected to board 0) in local mode.
C short addresslist[3] = {6,7,NOADDR};
EnableLocal(0, addresslist);
