Main Window:

The interface application is designed to provide a friendly and flexible interface to the controller. It allows the controller settings to be read and written, and the process temperature to be monitored. The main window of the interface application is shown below ( fig. 1 ). This is the initial view when the program starts. When you click on the ">" button, the extended view will appear ( fig. 2 ) and if the controller is connected to the right COM port, the configuration data will be received.
