Interactive Control (Usage Notes)
ibsic
Input
| ud | Board descriptor |
Output
| Function Return | The value of Ibsta |
Description
ibsic asserts the GPIB interface clear (IFC) line for at least 100 µs, then unasserts IFC. Asserting IFC unaddresses all devices on the bus and makes the interface board CIC.
The IFC signal resets only the GPIB interface calls of bus devices and not the internal device calls. Consult your device documentation to determine how to reset the internal calls of your device.
