4.11. MANIPULATING SIGNALS
Unit’s TAIP reference chapter and the Scenarios and Examples sections.
4.11 Manipulating signals
Signals marked with a (-) sign on the signals’ list on the Event Machine
section can be directly manipulated by the user. These signals are:
•
Outputs (4).
•
User Signals (10).
Signals’ manipulation and consulting is achieved with the
SS
TAIP message.
When setting/resetting an output with the
SS
message a direct hardware
activation/deactivation takes place on the selected output. See the Outputs
section on the Configuration chapter for more information.
4.12 User signals
User signals (U) are used to create complex configurations. User signals are
set or reset only with the
SS
message. Thus, they are used to trigger events
based on a user set/reset
SS
command or on a set/reset
SS
event user-action.
Refer to the Scenarios and Examples section for more information. The Safe
engine turn-off example is configured so that a user signal activation starts
the safe engine turn-off process. This user signal activation is not done
on the script as it is not part of the configuration of the unit but of its
operation: Whenever a remote system tries to turn-off the engine, a user
signal activation is performed by sending the TAIP
SS
command over the
air.
4.13 Using Heading Deltas (turn-by-turn report)
By using Heading Deltas , a turn-by-turn reporting criteria can be created.
This is achieved by making the unit report only when the vehicle’s heading
changes significantly since the previous heading-change report. To do so,
the
J signals are used. A J signal is automatically set high whenever the
vehicle’s heading changes by more than the delta value defined with a
XAGH
message. After being evaluated, the signal is set to low to enable further
triggers. Also, the heading value used for comparing the actual heading of
the vehicle is updated so a new heading change can be detected.
Heading-change detection is only done when the vehicle’s speed is
greater than 5mph.
Note:
A turn-by-turn report, having a delta value of 45 degrees, looks like:
