Template:FM36YX I/O settings

When no I/O element is enabled, AVL packet comes with GNSS information only. After enabling I/O element(s) AVL packet along with GNSS information contains current value(s) of enabled I/O element.


Permanent I/O elements (are always sent to server if enabled)
No. Property Name Description
00 Digital Input Status 1 Logic: 0 / 1
01 Digital Input Status 2 Logic: 0 / 1
02 Digital Input Status 3 Logic: 0 / 1
03 Digital Input Status 4 Logic: 0 / 1
04 Analog Input 1 Voltage: mV, 0 – 30 V
05 Digital Output 1 Logic: 0 / 1
06 Digital Output 2 Logic: 0 / 1
07 GNSS PDOP Probability * 10; 0-500
08 GNSS HDOP Probability * 10; 0-500
09 External Voltage Voltage: mV, 0 – 30 V
10 GNSS Power States:
0 – off state (when GPS module is off)
1 – Reserved
2 – GPS ready (antenna is working, but with no GPS fix)
3 – GPS working (antenna is working and has GPS fix)
4 – GPS sleep (when device is in GPS sleep mode)
5 – Overcurrent (The only condition to get value 5, then antenna is damaged and short circuit)

Monitoring

I/O monitoring starts after enabling I/O element and setting up I/O parameters as it is shown below:

Event generating

Events happen when the value of enabled I/O intersects thresholds (enter, exit or on both) predefined by High and Low level thresholds. Table below defines all available values of I/O settings.

Setting Value
Priority low, high
High level maximum threshold
Low level minimum threshold
Generate event on interval enter, on interval exit, on both enter and exit
Average constant 1 – 232 (4 Bytes)

I/O elements can generate events according to hysteresis algorithm. If I/O event operand “Hysteresis” is selected, events will be generated as it is shown in the illustration below (I/O speed is taken as I/O value example):
