Energy Management System DIN EN / ISO 50001

2. Scenario Previous Exercises JEVis Live System basics Open an analysis
Create own analysis
Task
Import data manually and create a calculation
Preconditions
JEVis Monitoring System with data

3. Steps Log-in into JEVis System Create Energy Node
Manual Energy Data Import
Create Mass Node
Manual Mass Data Import
Create EnPl Node
Create Calculation
Visualization of EnPl

4. 1) Log-in to the JEVis System
Start JEConfig and log-in
On JEVis Live System: Online via My-JEVis:
user name: Admin your own log-in data
password: jevislive

5. 2) Create New Nodes Add nodes for 2 Input data rows:
Main Electricity Meter (energy)
Production Output (mass)
Add node for 1 Output data row:
EnPI* (result of calculation)
* Energy Performance Indicator

6. 2) Create Energy Node
Click New Property → Float → Physical → Energy

7. 2) Create Energy Online Node
Click New → Datasource → Online

8. 2) Create Energy Online Node
The data will be imported manually
→ almost no settings have to be made
Important:
“Differential” is set to “true”
Uncheck “Create PrecalcCleaner DS”

9. 3) Manual Energy Data Import
Time Zone !
Format: “dd-MM-yyyy HH:mm:ss”;”Value”
→ First day of the month at 00:00:00
→ Value in W and as decimal

10. 3) Manual Energy Data Import
The input form provides a simple way to enter data manually
Example data
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "
" :00:00";" "

11. 4) Create Mass Node
Click New Property → Float → Physical → Quantity

12. 4) Create Mass Online Node
Click New → Datasource → Online

13. 5) Manual Mass Data Import
→ Value in t
→ pay attention to use identical time stamps

14. 5) Manual Mass Data Import
The input form provides a simple way to enter data manually
Example data
" :00:00";"262.00"
" :00:00";"298.00"
" :00:00";"292.00"
" :00:00";"385.00"
" :00:00";"388.00"
" :00:00";"370.00"
" :00:00";"405.00"
" :00:00";"298.00"
" :00:00";"262.00"
" :00:00";"298.00"
" :00:00";"300.00"
" :00:00";"400.00"

15. 6) Create EnPI Node
Click New Property → Float → Physical → Energy per ton

16. 6) Create EnPI Online Node
Click New → Datasource → Online

17. 7) Create Calculation Calculation is child node of “My Company”
Click New → Object → Data Gateway → GenericCalc
Set JobStatus to “CALCULATE”
Uncheck “Create PrecalcCleaner DS”

18. 7) Create Calculation
Your Registry should look like this:

19. 7) Create Calculation In the following steps you need
The Online Node ID of Main Electricity Meter for Energy Data
The Online Node ID of Production Output for Mass Data
The Online Node ID of EnPI for EnPI Data
Note the IDs from the Registry

20. 7) Create Calculation
Define Inputs
INPUT var=ID;
Define Output
OUTPUT ID=var;
Divisions in Octave
Take care of using the ./ operation for matrices

21. 7) Create Calculation Use the IDs of your data structure!
Save everything with the blue disc button
Set JobStatus to “FETCH”

22. Force Recalculation
Onto the JEVis Live System you have to
start the calculation of data by click on the
icons shown below:
Run JEJobMaster for fetching data and
calculation of Octave code
Run JECalc for calculation of clean data

23. JEVis Live System
Start JEGraph

24. JEGraph Login Type your User in the Username field
Type your Password in the Password field
Additional Features
The log-in dialogue entering of the
server address.
JEVis is multilingual. Select your
language from the drop down box

25. 8) Visualization of EnPI
Close the “load analysis” dialogue
Choose Analysis → new → JEChart

26. 8) Visualization of EnPI
Select “EnPI” data row from the Registry where you saved it
Always select the last year as time period

27. 8) Visualization of EnPI

28. Conclusion JEVis supports calculations in MatLAB / Octave syntax
JEConfig provides csv and manual data import
Calculations start automatically on server based JEVis Systems
