Note
The "alive and well" counter is a 3 bit modulo counter at the PP application level. The PP
application can be monitored using this counter. Failure of the application software does not
generally result in a communication failure, as this is developed in a hardware-supported
manner. The watch dog switches off the digital outputs, while the inputs remain at their last
set values.
