Interactive Control (Usage Notes)
|
DevClearList addrlist |
Input
| boardID | The interface number |
| addrlist | A list of device addresses terminated by NOADDR that you want to clear |
Description
DevClearList sends the Selected Device Clear (SDC) GPIB message to all the device addresses described by addrlist. If addrlist contains only the constant NOADDR, the Universal Device Clear (DCL) message is sent to all the devices on the bus.
Possible Errors
| EARG | An invalid address appears in addrlist; 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. |
