NI-488.2 Routines — SetRWLS
SetRWLS
Purpose
Place devices in Remote With Lockout State.
Format
C
void SetRWLS (int boardID, Addr4882_t *addrlist)
Visual Basic
CALL SetRWLS (boardID%, addrlist%())
Input
boardID
addrlist
The interface board number
A list of device addresses that is terminated by NOADDR
Description
SetRWLS places the devices described by addrlist in remote mode by asserting the
Remote Enable (REN) GPIB line. Then those devices are placed in lockout state by the
Local Lockout (LLO) GPIB message. You cannot program those devices locally until the
Controller-In-Charge releases the Local Lockout by way of the EnableLocal NI-488.2
routine.
Possible Errors
EARG
Either an invalid address appears in addrlist or the addrlist is empty;
ibcntl is the index of the invalid address in the addrlist array.
EBUS
ECIC
EDVR
ENEB
EOIP
ESAC
No devices are connected to the GPIB.
The interface board is not the Controller-In-Charge; see SendIFC.
Either boardID is invalid or the GPIB driver is not installed.
The interface board is not installed or is not properly configured.
Asynchronous I/O is in progress.
The interface board is not configured as System Controller.
