This procedure will use switching logic to add the pseudo analog point. With the RIO plant having the focus, go into
switching logic. Select the
Software Points menu item and then Pseudo Analog. The Create/Select Software Point <Va>
dialog box will be displayed. Type in a New point name for the enthalpy sensor (such as OaEnthaply) and click on the OK
button. The new point that was just created will be added to the screen as the header point for switching logic table and
also added to the
Point List . Select the Cancel button to exit the Create/Select Software Point <Va> dialog box. Exit
switching logic by selecting the File menu item and Exit. CARE will display the Delete Unused Software Points list box.
Click the Cancel button to continue.
2. Go into the Data Point Editor (Controller/Edit/Data Point Editor) and under Point select the pseudo analog point that was
just created and click the OK button. Select the drop down list for the Engineering Unit and scroll through the list until the
mA (mA matches the engineering unit of the RIO input) engineering units are displayed. Select the mA engineering unit
that is shown with one decimal place (number 66) and click the OK button to save the selection. Cancel the User
Address list box and select File/Exit to exit out of the Data Point Editor.
3. Translate the Zone Manager and Export the Zone Manager files to E-Vision by selecting the Project and Export to E-
Vision menu items. Type in the name of the Zone Manager Export file when the Export Zone Manager dialog box is
displayed. Select the project and the Zone manager within that project that is being exported and click the
Export button.
Exit CARE and Start E-Vision. Select the E-Vision project to open and the CARE Export Filename created above. Once
the project is open, select the RIO device that the enthalpy sensor is connected to and go into the Application Selection
screen (offline) by selecting the
Controller, then the Application Selection menu items. From the Inputs tab of the
Application Selection dialog box, add Oa_Enthalpy to either analog input 5 or 6 and select the OK button to save the
selection.
4. Select the Controller menu item and then Import from CARE to import the Zone Manager files with the new pseudo
analog point. If this function has already been performed before, the user will be prompted with the message CARE
Export File has already been imported, do you want to import again?. Select Yes to continue with the Import. When the
import is finished, E-Vision displays the message CARE Export File has been imported. Select
OK to continue.
5. Select the Network menu item and then Map C-Bus Points. Select RIO1 as the Controller Type from the Map C-Bus
Points dialog box. Under Unmapped CARE, select the name of the RIO device that the enthalpy sensor was added to in
CARE. Under
Unmapped Excel 10, select the name of the RIO device that the actual enthalpy sensor was added to
(both names should be the same). Next, select the Custom button and the Custom Mapping CARE Points dialog box will
be displayed. Select the OaEnthalpy point under CARE Points and CurrentAI under Excel 10. CurrentAI is the user
address in the RIO device that contains the actual sensor value for the OaEnthalpy (C7400A1004, 4 to 20 mA device).
Select the Map button to add the OaEnthalpy point to the list of Mapped Points. Click on the Close button to exit the
Custom Mapping CARE Points dialog box. Click on the Close button to exit the Map C-Bus Points dialog box.
6. To use the OaEnthalpy custom mapped point with other Excel 10 controllers on the E-Bus, select the Network menu item
and Refer Excel 10 Points. Select the RIO device name as the Source Excel 10 and then scroll down the list of Excel 10
Points: until you reach CurrentAI and select it. Select an Excel 10 controller from the Destination Excel 10 list. For
example if the user had selected a CVAHU controller from the
Destination Excel 10 list, the user would select from the
Excel 10 Points list as the destination point and then click on the Add button to add the point association (Binding)
between the RIO and CVAHU controllers. If
DestOaEnth is already being used in an association, then the message At
Least one of the output network variables is in an existing connection and E-Vision will not allow this association to be
added. In order to add this association, the user has to remove any other associations with the
DestOaEnth point. Select
the Close button to exit out of the Refer Excel 10 Points dialog box. Any controllers involved in the new association or
change in an existing association will require commissioning.
7. Select the Controller menu item and the Update Zone Manager Files. E-Vision will add the custom mapping information
to the Zone Manager files. When the Update Zone Manager Files function is done, commission any controllers that need
to be commissioned, then close the E-Vision project and exit out of E-Vision.
8. Start CARE and open the Zone Manager that was just updated through the Update Zone Manager Files function and
start XI584 by selecting the Controller, Tools and XI584 menu items. Once XI584 is started, select the Utilities and File
Transfer menu items and select CARE Import. Select the project and the Zone Manager that was just updated and select
Import and click OK on the Select Target Controller dialog box. When the CARE Import is complete, close the CARE
Import dialog box. If this is the initial loading of the Zone Manager, then it will have to be reset and the CPU address set
by the XI581 Emulation function (
Applications, XI581 Emulation menu). Select the Utilities, File Transfer menu items and
select Download. The Download dialog box will be displayed. Check the All selection and click the Controller button.
When the Select Controller/Subsystem dialog box is displayed, make sure that the correct CPU address or name is high
lighted and select the OK button. Click the Download button and click Yes to the message Replace updated application
part in controller (CPU address or Controller name). When the download is complete, exit out of the Download dialog
box. From the XI584 main menu, select the Data, Access by User Address menu items. Type OaEnthalpy in the Search
For User Address and click the Search button. When the OaEnthalpy point displays in the User Addresses list, click on
the point and select the
Attributes button. XI584 will now display the value of the enthalpy sensor connected to the RIO
device. This point can now be used in the Zone Manager control strategy or switching logic. This point can be used in
other Excel 5000 (C-Bus) controllers by assigning a global analog point in the destination controller with the user address
name of OaEnthalpy. Refer to the CARE User’s Manual form, 74-5587 for information on creating global points in Excel
5000 controllers.
ADDING OTHER VOLTAGE/CURRENT SENSORS
See Table A-1 for the supported Voltage/Current analog input sensors that can be connected to the RIO Device. The user
must add a software point (pseudo analog - in RIO CARE Plant) that can be mapped to the actual hardware input (RIO Plant)
through the Custom Mapping function of E-Vision. The procedure described previously for adding an enthalpy ( 4 to 20 mA)
sensor should be followed and instructs the user on adding the pseudo analog point in the RIO CARE Plant and using the
