2.8.3 DUT-E CAN readings totalizing
ATTENTION: S6 Technology allows to summarize fuel volume indications of
up to 8 pcs. of DUT-E CAN sensors. Each sensor should be assigned a unique network
address within the range 101…108. Fuel tank calibration table should be stored in the
internal memory of each DUT-E CAN connected to S6 bus (see 3.10.7).
1) To receive data on the measured total volume of fuel of two and more Vehicle
tanks via RS-232/RS-485 interface, you may use MasterCAN C 232/485 vehicle data
interface together with DUT-E CAN sensors. In order to receive data on the total volume of fuel
via RS-232 interface, you may use MasterCAN V-GATE together with DUT-E CAN.
See annex D for connection scheme of MasterCAN and DUT-E CAN and order codes of required
cables.
Check out MasterCAN Operation manual for detailed information on vehicle data interfaces
MasterCAN C 232/485 and MasterCAN V-GATE.
2) DUT-E CAN sensors with 4.6 and higher can be used for obtaining data on total
fuel volume of several tanks under CAN j1939/S6 interface.
See annex B for connection scheme of DUT-E CAN and order codes of required cables.
To get correct values DUT-E CAN should be configured with Service DUT-E software (version
3.25 and higher). Configuration instructions (see 3.10.4):
• select the highest address for N
n
sensor at Settings-Operation modes module.
For the correct and fast data transfer from sensor to sensor network addresses N
1
to N
n-1
should be consequent.
• set Master for N
n
sensor in Summator drop-down list.
• set Slave status for N
1
to N
n-1
in Summator drop-down list.
• set Off in drop-down list if there no need for totalizing
• shut down Service DUT-E since configuration is made because the further operation
of the software blocks data exchange between DUT-E CAN.
Summerized data of fuel volume (PGN 62982, see annex C) are provided only by the sensor
which is assigned Master status.
