Terms and Definitions
Server
— hardware and software combination of Telematics Service ORF 4, designed for
Operation Data processing and storage, also for generation and transfer of Analytical Re-
ports upon User's request.
Event
— relatively rare and sudden change in SPN. For example, the attempt to falsify val-
ues of ―Instant fuel consumption‖ counter by applying electromagnetic field to fuel flow me-
ter will be recognized as ―Interference‖ Event. An Event can have one or several character-
istics. ―Interference‖ Event has the following: date/time and duration of interference. When
the Event occurs, a terminal unit registers the time of occurrence, which is later mentioned
in a report on the event. Thus, the Event is always attached to exact time and place of oc-
currence.
Counter
— cumulative numerical characteristics of Parameter. Counter is represented by a
number, which can only grow in time. Examples of Counters: fuel consumption, engine op-
eration time, total distance and other.
Telematics system
— complex solution for real-time and after trip vehicle monitoring and
control. Main vehicle parameters monitored: route, fuel consumption, operation time, tech-
nical condition of vehicle, safety. Consists of OE, Communication channels, Telematics Ser-
vice ORF 4.
Vehicle
— an object controlled within Telematic system. Usually Vehicle means a truck,
tractor or bus, sometimes a locomotive or river boat. From Telematic system point of view,
stationary objects are also considered to be vehicles: diesel gensets, stationary tanks,
boilers/burners.
Function Module
(FM) — unit-embedded component of hardware and software combination,
executing a group of special functions. Uses input/output PGNs and settings PGNs.
Unit
— an element of Onboard Equipment of Vehicle, which is connected to Telematics In-
terface S6. Particularly, in this document Unit means DFM fuel flow meter.
