3. Register the ACME Example C# Device Plug-in (Version 1.0) plug-in and observe register
command calls.
The following image shows a representative message box seen during the instantiation of the
example plug-in. You must click the OK button in a timely fashion to allow normal plug-in
operation, otherwise the director may time out waiting for the plug-in to respond. If you choose to
Cancel the Plug-in API call instead, the director will be notified that the Plug-in API call has
failed. Note that the pop-up message box may sometimes be obscured by other application
windows, but you can see and select it on the Windows task bar.
4. Execute the ACME Describe Device command on a device in your network. To do this with the
LonMaker tool, right-click the device, point to Plug-ins, and then click ACME C# (Describe
Device) on the shortcut menu.
