Description of an AS-i V2 module's debug screen

At a Glance

The debug screen dynamically displays the status of the AS-i V2 module and the devices which are connected to the bus.

It also allows access to the adjustment of the slave parameters and to the channel commands (forcing the input or output value, Set/Reset of an output, ).

NOTE: if in your user program you use the function READ_STS () to read information relating to the AS-i V2 module, it is important not to carry out this function more than every 5s otherwise the debug screen will not display correctly.
