Not that it needs it, but The SmartPAC 2 has the most extensive diagnostic capabilites of any press control.   You can view the resolver signals, the status of inputs and outputs (this is invaluable during installation), as well as the internal event and error logs. 

In addition, this diagnostic information can be sent directly to the Wintriss Technical Support department using SmartPAC 2's messaging feature, or can be downloaded to a USB disk via SmartPAC 2's built-in USB port.
