1. Hardy 3030 Home Page
These slides will walk you through setting up the mapping to send a “Tare” command to the HI 3030 unit. This same principle would be used for other commands in this unit as well as in other units like the HI 3010, or the HI This will walk through an example of doing a mapping equation. For more information on mapping, you can click on the link to a “Technical Paper on Mapping” found on the mapping Source page and get a PDF file explaining mapping in more depth.
Here you have the Home page for the HI 3030 controller. From this page, you would click on the link to Configuration.

2. Configuration Menu Selection
Here you see the configuration menu selections. For setting up the Tare command, you will need to set up a mapping equation. Click on the link to the Mapping Setup.

3. Here you see the mapping setup page 1. This is the Destinations page
Here you see the mapping setup page 1. This is the Destinations page. Here you will choose the Destination for the mapping equation. The Destination is just that, where the data will go. This may be a data location for a parameter, like span, a command like tare, or a Network location to send the data to. Every equation will have a Destination and only one Destination. This is always the left side of the equation.
You will notice you have several categories of pull down menus to choose from. Each category may have several related selections to choose from. For our example, the Tare command, we would look in the Control category. If you don’t know which category a selection would be found in, you may pull down any selection to “hunt” for it.

4. Once we open the Control menu, we will find the Tare command
Once we open the Control menu, we will find the Tare command. We would highlight this selection and click on it. NOTE: The “Tare” command is listed as “Tare”, not to be mixed up with the Tare Wt, which is the tare value.

5. Once you have selected the Tare command, you will notice it will show another selection for the channel you want to run the Tare command on. This will only show up on the HI 3030, as this is the only multi-channel unit. You would want to enter the channel you wish to run the command on and click on select. For this example, we will use channel 1.

6. Once you have made the selection for the destination of the mapping equation, you will want to click on the “Jump to Source Page”. Here you see the Source page. This page looks similar to the Destination page, however, the selections in the pull downs will differ. Here is where you will select where the data will come from. This could be an input contact, a network registers, or some register within the unit itself. For our example, we will be using an input from the DeviceNet network. So, we will pull down the Networks selection.

7. As you can see, we will have network choices for all network connections to our unit. For this example, we will look at the DeviceNet selections. You will notice that as a source, we can use either the DeviceNet output or Input selections, and we have different formats of these selections. We can choose Boolean for a single bit selection, the Short Int for a 16 bit register (word), Int for a 32 bit register (DINT), or Float (32 bit IEEE) register.
For our example, since the Tare command only needs a bit signal to turn it on, and we want this signal to come from the PLC, we will choose DeviceNet Boolean In.

8. Once we make the selection for DeviceNet Boolean In, it will open the selection for which word and which bit within that word to use. Enter these selections and click on the select button.

9. Mapping Window
Once you have made the selections, you will notice that during this process, each selection you make will add to the equation in the mapping window. For our selections of Tare channel 1 = DeviceNet Boolean In, word 1, bit 0, we will have the equation HO1.0 = DI1.0. At this point you would click on the Map button to actually enter this mapping equation into the unit. If you click on Map and it does not add the equation to the current mappings, then there was something incorrect in the equation.

10. Current Mapping
As seen here, once the Map is done, it will add the equation to the current mappings. Now, when bit 0 of DeviceNet input word 1 is set high, the unit will tare channel 1.
If you had any further mapping to do, you would click on the Return to Destination Page button and start the process again for the next equation.
