Dialog Box=>Data Filter

To import a subgroup of data a record filter can be specified. For example a filter that only data will be imported where a certain channel is above a specified threshold (e.g. Torque > 10 Nm).

Channel

List of all available data channels.

Comparison Operators

The following operators are available:

Value	Meaning
==	equal or with tolerance
>	greater than
<	less than
<=	less than or equal
>=	greater or equal to
!=	not equal to

Value

Sorted list of the data values. If the channels contains more than 8000 data points only the first 8000 points will be listed.

Tolerance

For the == operator a tolerance in percent or an absolute value can be specified. To avoid a tolerance set the value to 0 or clear the field.

Up to seven filters can be logically linked using one of the following operators:

Value	Meaning
AND	logical AND
OR	logical OR

The AND operator has a higher precedence than the OR operator. Parentheses cannot be used.

Comment

Filters can only be specified for NC files where all channels have the same number of data points.

For the filter a new channel with the name __Filter__ will be added to the NC file. Only data points where __Filter__ is 1 will be imported.

In a filter numeric and text channels can be used. For text channels the wildcards * and ? can be used. The asterisk character (*) substitutes for zero or more characters. The question mark (?) substitutes for exactly one character. Example Mode == On*
