9.1.5 Event mess ages
If exceptional events occur (alarm activation, entering and exiting programming, switching on and off etc.), the
matrix communicates an event message to the PC, which includes an event code and the time at which the
event occurred.
The format of a typical event message is '[2002/06/19 12:15:02 reset uC]'
The following table lists the event messages:
