Creating Permission Groups

You can create new permission groups for other sets of users. For example, you might need a permission group that reads only predefined data items, unlike the DefaultReaders group. Predefined items can have special read and write access groups. You can specify which groups can create items, write items, and read items. As a result, different computers can have individualized access to different predefined items.

Complete the following steps to create a new permission group that reads or writes to a predefined data item.

1. Launch the DataSocket Server Manager by selecting Start»Programs»National Instruments»DataSocket»DataSocket Server Manager.
2. Click the New Group button.
3. Enter a descriptive name for the permission group in the Name textbox.
4. Modify the Hosts list to include the computers to which you want to grant access. You can specify a computer either by the computer name on the network or the IP address in dotted decimal notation. The DataSocket Server Manager also has two variables, localhost and everyhost; localhost represents the local computer (the computer where the server is running) and everyhost represents all computers (unrestricted access).
5. Select the data item to which you want to grant access from the Predefined Data Items list, and then select the new permission group from the Read Access or Write Access pull-down menu.
