digital data

Set of digital data that you want to use for a comparison.

datatype_icon

comparison

Value that the specified digital data is compared to.

Name Value Description
Equal 0 0 Force Down
Equal 1 1 Force Up
Equal Z 2 Force Z
Equal L 3 Compare Low
Equal H 4 Compare High
Equal X 5 Compare Don't Care
Equal T 6 Compare Invalid
Equal V 7 Compare Valid
Equal 0 or L 8 Equal to Force Down or Compare Low
Equal 1 or H 9 Equal to Force Up or Compare High
Not Equal 0 or 1 10 Not Equal to Force Up or Force Down
Not Equal 0, 1, L, or H 11 Not Equal to Force Up, Force Down, Compare Low, or Compare High.

Default: Equal 0

error in

Error conditions that occur before this node runs. Unlike most nodes, this node runs normally even if an error occurs before this node runs.

Default: no error

datatype_icon

comparison results

A Boolean array that indicates whether any values in the specified digital data matches the comparison condition. This array is the same size as the array of digital values in the specified digital data.

True Values in the specified digital data match the comparison condition.
False Values in the specified digital data do not match the comparison condition.

passed?

A Boolean that indicates whether all values in boolean array match the comparison condition.

True All values in boolean array match the comparison condition.
False Not all values in boolean arraymatch the comparison condition.

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Where This Node Can Run:

Desktop OS: Windows

FPGA: This product does not support FPGA devices

Web Server: Not supported in VIs that run in a web application
