ADDING DIGITAL INPUTS

 

See Table A-2 for the supported Digital input types that can be connected to the RIO Device. The user must add a software point (pseudo digital nstate - 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. The user will add a Pseudo Digital nstate point (<Vd>) in step one instead of the Pseudo Analog to the RIO CARE Plant and then use the Custom Mapping function. From there it can be used with other Excel 10 controllers (referenced) on the E-Bus, that are used in Zone Manager control strategy or switching logic, or are used with Excel 5000 controllers on the C-Bus.

ADDING DIGITAL OUTPUTS

 

See Table A-3 for the supported digital output types that can be connected to the RIO Device.

The user must add a software point (pseudo analog) that can be mapped to the actual hardware output through the Custom Mapping function of E-Vision. The following procedure will instruct the user on adding the pseudo analog and using the Custom Mapping function so that the Digital Output can be used in the Zone Manager control strategy or switching logic, or be used with Excel 5000 controllers on the C-Bus.

1.With CARE running, open an existing RIO plant. The user can go into either switching logic or control strategy to add the pseudo analog point. If the user does not have an existing control loop through control strategy, use switching logic to add the pseudo point, otherwise a control loop will have to be created along with unnecessary RACL to add the point. 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 Digital Output (such as MiscExhFan) 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 the OK button. Select the drop down list for the Engineering Unit and scroll through the list until the Pct engineering units are displayed. Select the Pct engineering unit that is shown with one decimal place (number 55) and 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
