SetRWLS
Purpose
Place devices in Remote With Lockout State.
Format
C
void SetRWLS (int boardID, const Addr4882_t *addrlist)
Visual Basic
CALL SetRWLS (boardID%, addrlist%())
Interactive Control (Usage Notes)
SetRWLS addrlist
Input
| boardID | The interface number |
| addrlist | 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 call.
Possible Errors
| EARG | Either an invalid address appears in addrlist or the addrlist is empty; Ibcnt is the index of the first invalid address in the addrlist array. |
| EBUS | No devices are connected to the GPIB. |
| ECIC | The interface is not the Controller-In-Charge; see SendIFC. |
| EDVR | The NI-488.2 driver is either configured incorrectly or is not properly installed. |
| EHDL | boardID is out of range. |
| ELCK | The requested operation could not be performed because of an existing lock by another process. |
| ENEB | The interface is not installed or is not properly configured. |
| EOIP | Asynchronous I/O is in progress. |
| ESAC | The interface is not configured as System Controller. |
