2.2.9- Equations for recording status changes (EVENT)
This function allows to store, in chronological order, the status change of the real input points and of the
virtual points that have been specified in the EVENT block. Each status change will be stored together to:
Day/Month Hour:Minutes:Seconds
The EVENT function allows to specify if MCP 4 has to store the OFF-ON or the ON-OFF status change or
both. The EVENT function will also automatically register the so called “system events”, that are the failure
and the restoring of any module and of the bus; the doubled address events will be automatically registered
too. Up to 2048 events can be stored in the RAM.
The section of the RAM where these events are stored has the battery back-up feature, therefore the events
remain stored even if the main supply voltage fails (at least until the battery does not reach the minimum
retaining voltage of the memory).
Keyword:
EVENT
Create the event list (fixed buffer): when the buffer is full, it does not accept any other
event (in this way the list contains the first 2048 events from the last cleaning of the
buffer)
EVENTC
Create the event list (circular buffer): when the buffer is full, it overwrites the old
events (in this way the list contains the last 2048 events)
No more than 1 EVENT block can be declared in the same MCP 4 module. If the buffer is full (case EVENT)
or the old events have been overwritten (case EVENTC), then the virtual point
V2008
will be activated to
report this occurrence.
