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)
Description Voltage Duration
Normal operation 10-30V Unlimited


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):
