There are two types of operations with Permanent I/O elements: simple
monitoring and event generating. Monitoring method is used when current
I/O information needed with regular GNSS coordinates. Event generating
method is used when additional AVL packet is needed when current value of
I/O exceeds predefined High and Low levels. I/O settings allow defining I/O
event criteria
.
Figure 48. I/O settings
Enabled or disabled field – allows enabling I/O element so it is added to the data packet
and is sent to the server. By default all I/O element are disabled and FM3622 records only GNSS
coordinates.
Priority (AVL packet priority) can be low, high or panic. Regular packets are sent as Low
priority records. When low priority event is triggered, FM3622 makes additional record with
indication that the reason for that was I/O element change. When High priority is selected,
module makes additional record with high priority flag and sends event packet immediately to
the server by GPRS. Panic priority triggers same actions as high priority, but if GPRS fails, it sends
AVL packet using SMS mode if SMS is
enabled in SMS settings
.
High and Low levels – define I/O value range. If I/O value enters or exits this range, FM3622
generates event. “Generate event” parameter defines when to generate event – when value
enters defined range, exits it or both.
Averaging constant – it is an I/O event delay parameter. In some applications there is no
need to generate events on every I/O range enter/exit immediately. Sometimes it is necessary to
wait some time interval before event generating. Averaging constant allows setting I/O event
delay (averaging). If I/O value is entering or leaving predefined range, it must have same value
for Averaging constant time. 1 Averaging constant value equals about 30 miliseconds. In Deep
Sleep mode there is no Averaging.
