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);
