Diepni:
What version of ComponentWorks do you have? Since the NI-6601 board came out after ComponentWorks 2.X, that version of ComponentWorks does not support the NI-6601. Support was added for this board in ComponentWorks 3.0.
If you would prefer, you could instead program your 6601 directly with NI-DAQ from Microsoft Visual Basic. NI-DAQ ships with some Microsoft Visual Basic examples you may be interested in. A number of these examples are written specifically for the TIO ASIC on your 6601 board and can be found under NI-DAQ\Examples\VBasic\Ctr.
There has been a number of enhancements added to version 3.0 of ComponentWorks. You can read more about these differences at the following URL.
