Buttons New Folder and New exist in the Device Manager view of a device-level component under any driver network. Use of New Folder is optional. Typically, you use New only if the driver does not support online discovery, or if you are programming offline.
New Folder and New are also on the Device Manager toolbar and the Manager menu.
The button in the Device Manager adds a special “DeviceFolder” component you can use to organize devices. This is equivalent to copying that same component from that driver’s palette. A Name dialog lets you name the folder before it is created (Figure 18).
When you click OK, a new DeviceFolder component is added under the network.
A driver’s DeviceFolder component is different than a “normal” Folder component, as it provides that driver’s Device Manager view by default (just like the parent network
component). Also, an “All Descendants” command is available from the root Device Manager, which allows you to see all devices in the network. For details, see All Descendants.
The New button in the Device Manager allows you to add a new device component to the station. This is equivalent to copying a device component from that driver’s palette. The New dialog provides a selection list for device type, and also the number of devices to add (Figure 19).
When you click OK, a new device-level component is added under the network. You usually need to edit specific details for each new device, including addressing parameters for communications.
