Next, in settings page, browse to the folder Real-time Diagram Setup and collapse the folder like below: • • • • • •
Click on STEP1 to configure the page names and enabling/disabling the 5 possible pages. EM100 allows users to program up to 5 real-time diagrams.
Check the Enable box to display the diagram on the WEB page. Unchecking this Enable box will hide this specific diagram.
Enter the desired application name in the text box under Diagram Name column. The diagram name will be shown at the real-time diagram WEB pages to distinguish between various diagrams.
Next click on STEP2: Upload the background image you want to display as the back drop of the real time diagram. Click on Upload. When the diagram is not uploaded ie. First Install, the diagram ima ge appears with a grey “X”. Uploading a new image will display this new image in the thumbna ils replacing this “X”. To replace an existing image, click Upload button again and overwrite with another replacement image. It is best to use a large resolution image as the background as the image may stretch. Try uploading the image on the diagrams you will use only.
Next click on STEP3: This step places the diagram objects on the diagram and applies connections to measurement parameters to the objects.
EM100 supports maximum 60 objects per single real time diagram. For scenarios requiring more display objects, it is advised to use multiple real time diagrams to accomplish this task, ie. one diagram shows the main electrical diagram, another diagram shows the HVAC parameters
Select the correct diagram that you want to configure by clicking on the menu at upper right as below:
Check the check box und er each item (1-60) toenable the object. If the “item” is not checked, this object will not be displayed in the real time diagram.
Do NOT enable the check box if you do not intend to use these objects. Only use the ones necessary.
Type in the name to be displayed for this object und er the “Name” text box. Please note there is a limitation on the length to avoid going off the screen. All text boxes allow multiple languages.
These are the supported ob jectsand their corresponding descriptions of each:

The last step “Data Link” links the object to a measurement or a variable. Linking an object turns the object “alive” by connecting the object to an actual value. Objects can be linked to many types of data points, and each type of object can link to a specific set of measurements or variables. Numeric objects can apply arithmetic formulas prior to displaying the real-time value. Please refer to the list below.
The formula box above is the area where you can manually type in any formula that satisfies the condition. For example, you can input a number “3” in this text box, then the data will display the constant 3 in the real time diagram. Using the formula box is not
recommended unless you are an advanced user, normal users follow the steps by clicking the devices and clicking on their respective measurement signals.
For connecting to a monitored object, select the Device in the left vertical list under the formula box, click on the object being
monitored. For example, you can select an expansion unit, Modbus slave device, power meter, or even EM100 itself.
For connecting to a data point, select the parameter in the right vertical list under the formula box, click on the parameter being monitored. All parameters that are monitored in the device will be listed. For example, you can select kVA if you choose to select a power meter.
For advanced setup, you can type in formulas with arithmetic operators to enhance the calculation. Learn more in the Using Formula section.
Go to Settings and then Database Management. Under the heading Real-time Diagram Import/Export, click on Export Real- time Diagram as shown below. Make sure you shut down the database by closing the connection before continuing. By clicking on Export you will download the “OneLineDiagram.tar” file and save it on your computer.
Users can restore the previous saved real-time diagram file by clicking on Import Real-time Diagram a nd pointing to the OneLineDiagram.tar file saved before.
