Rosemount 2410
Appendix C. Advanced Configuration
C.8.1 Delta Level
Calculation
The following example illustrates how to use TankMaster WinSetup to
configure a Rosemount 2410 to calculate the difference between product
levels for two tanks Tank 1 and Tank 3. The result is stored in tank
measurement variable Delta_Level in Tank 1.
A Virtual Relay Output can be configured to use the measurement variable
Delta_Level as source parameter to trigger the relay whenever the level
difference exceeds a specified value. See “Relay Output” on page C-6 for
more information on how to configure relay functions for a Rosemount 2410.
Figure C-13. Arithmetic
operations are configured in
Holding Registers 4800 to 4879
Figure C-14. The result is
displayed in Input Register 4800
and higher
1. Choose subtraction.
2. Put the result in Tank
Measurement Variable
TMV_Delta_Level.
3. Put the result in Tank 1.
Now the result will be stored in
TMV_Delta_Level for Tank 1.
4. For arithmetic operation
parameter A choose Tank
Measurement Variable=Level.
5. Choose arithmetic operation
parameter A from Tank 1.
6. For arithmetic operation
parameter B choose Tank
Measurement Variable=Level.
7. Choose arithmetic operation
parameter B from Tank 3.
