Specify Filter Criteria dialog box

Use the Specify Filter Criteria dialog box to control the number of items displayed in the Available Items window of the browser. After you set filter criteria, it applies to the items shown for any group selected in the Branches window of the browser.

Click the Filter button on the browser to open this dialog box. Click OK to close it and activate the filter criteria; click Cancel to close with no filter criteria set.

Note: Filter criteria stays in effect on displayed browser contents until the browser is closed. At that point, the filter dialog box displays the default settings, as shown below.

The filter dialog box provides three sets of filters:

• Item Name- Type a specific item’s name or use wildcards (* and ?) to widen the range. Default setting is all item names (*). Wildcards function like typical Windows wildcards: * replaces several characters, ? replaces a single character.

• Item Data Type- Select "Any" or one of the following OPC data types: short, integer, float, real, currency, data, string, boolean or unsigned char. If the data type is an array element, click the checkbox. The item syntax for array elements is <sg>.Attribute(<item>)[<index>]. Default settings are "Any" and unchecked.

• Item Access Rights- Select the type of OPC access rights of the desired items: Readable Only, Writeable Only or Readable and Writable. Default setting is "Readable and Writable."
