DESCRIPTION
4.
High Level - define I/O value range. If I/O value enters or exits this range, FM6320
generates event.
5.
Low Level – define I/O value range. If I/O value enters or exits this range, FM6320
generates event.
6.
Generate event – defines when to generate event. When value enters defined range,
exits it or both enters and exits.
7.
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 to be ensuring that
current event is not a short time event. 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. One unit of averaging constant value equals 20
milliseconds.
Selected data source value input averaging constant are calculated by following
formula:
Where:
VAL
Mean
– Value calculated during actual cycle
6
;
VAL
Mean-1
– Value calculated during previous cycle;
CONST – Averaging constant;
REALVAL – Real value detected on digital input.

I/O properties
I/O properties are additional data sources, which are recorded along with usual GPS data.
IO#0 (ID=x300)
I/O#0 priority
Parameter defines I/O property type of priority: 0 is disabled, 1 is low, 2 – high, 3 – panic,
4 – SW21, 5 – SW22, 6 – SW23, 7 –SW24.

I/O#0 High level
Parameter defines high value of triggered I/O property. This parameter is used to set
thresholds for I/O properties to generate events.
