4 SETTING PROCEDURE AND DEFINITION OF THE PARAMETERS
4.1 SETTING PROCEDURE
When the whole system is connected the following steps have to be followed to start
the system up:
1. Set the local parameters in each one of the installation components (UDat /
UDat Power+, UValves, UCounts, UVision, etc.). These local parameters are:
address, End of Line resistor and Filter CAN (this one only for UDat / UDat
Power+)
2. Set the global parameters of the installation from the UTrack, these
parameters define the hose reels, tanks, language, scenario of data
introduction, etc.
3. Make the probes calibration if UTank is installed.
4. Send this configuration of the global parameters from the UTrack to the rest
of the system.
4.2 ADDRESS DEFINITION
Each component on the network must have an address.
Each component must have an address that is unique in its family. 3 types of families
are distinguished:
- Family I. UDat / UDat+
- Family II. UValve, UCount, UMeter / UMeter+.
- Family III. UView.
- Family IV. UTank.
The numeration in each family goes from 1 to 127, without leaving EMPTY SPACES:
- The UDat / UDat Power+ will have the following numeration: 1, 2, 3, etc...
- The UValve, UCount, UMeter / UMeter+ 1, 2, 3, etc...
Note: In the case of this family, the address corresponds to the number of
a hose reel.
- The UViews are numbered with 1, 2, 3 etc...
- The UTanks are numbered with 1, 2, 3 etc...
Two units in the same family must not have the same address.
4.3 END OF LINE (EOL) RESISTORS
In the standard case, the components in the end of the network will have the line end
resistor connected.
