Universal Library Virtual Instruments (VIs) Counter VIs
Counter VIs
The Universal Library for
NI LabVIEW extensions provides VIs for the initialization and configuration of
counter chips. It is important to note what this means:
ƒ VIs can configure a counter for any of the counter's operations.
Counter configuration does not include the use of counters —such as event counting and pulse width.
Counter use is accomplished by programs which use the counter VIs. Some counter-use VIs are available.
To use a counter for any but the simplest counting VI, you must use the information contained in the chip
manufacturer's data sheet. Technical support of the VIs does not include providing, interpreting or explaining
the counter chip data sheet.
