You can find the allocation of the variables for this example
in the table below.
13. Click on the variable in the list that you want to
allocate the placeholder to.
Allocate the following variables to the placeholders:

You have completed the configuration for logging
specific data bytes.
5.2.4 Logging GNSS position data
The GNSS position data contains information on
longitude and latitude, altitude, direction, and speed as
well as time and date. Data is only logged when valid
position data is received.
1. Click on the GPS functionality folder.
2. Set and save the following:
Table 28: GPS functionality
Variable
Function
o
nCe
per
file
Each logfile contains position data at least once.
e
naBleD
Enables/ disables the position data logging.
AND / OR
AND: Position data is logged if both conditions (time
and distance) are met.
OR: Position data is logged if one of the conditions
(time or distance) is met.
l
ogging
p
erioD
(s)
Time period during which the position data
should be logged.
l
ogging
DistanCe
(
meters
)
Distance between the last position logged and the
current position (linear distance).
NOTICE
Oversampling due to too-frequent logging of GPS position
data will cause high data consumption or high number of
write cycles on the internal memory.
At the following settings, the position data is logged every
100 ms:
Logging period = 0
Logging distance = 0
These settings generate a high data consumption. If there
is no mobile radio connection, the position data is written
to the device’s internal memory instead. This considerably
reduces the service life of the internal memory.
•
Under Variable Logging period, enter a value >= 2 s
because the device only receives new GPS data every 2 s.
•
Under Variable Logging distance, enter a value above the
GPS accuracy.
5.2.5 Configuring the logging of internal variables
You can log various internal variables. Internal variables can
be both device variables and interface variables.
To log internal variables, you need an object
a
Ction
-
f
unCtion
- o
peration
in the object dictionary group
o
peration
m
anager
. With the object
a
Ction
– f
unCtion
–
o
peration
,
up to 8 internal variables can be logged in one process as a
virtual CAN message.
