Hysteresis
Figure 32 Hysteresis parameter configuration
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):

Data
Data is saved as I/O elements. OBD I/O elements must be enabled using configurator. All
OBD elements are configured in same logic as other I/O property elements (
Figure 34
).
SCAN function.
SCAN function allows user to automatically scan for available messages on OBD. FM1000 can
scan available OBD messages if ALL of these conditions are met:
•
Ignition must be ON.
•
Device connected to vehicle through OBD and to PC with USB.
