Configure Two SCADAPack Modbus Digital Input Points

Each digital input on your SCADAPack Modbus controller can be represented in your system by a SCADAPack Modbus digital point. The configuration of the point defines whether its states trigger alarms, its retrieval rate, address, and so on.

For this tutorial, you are going to create two digital input points which will represent two of the digital inputs on your SCADAPack Modbus controller:

1. Display the Database Bar (see Display an Explorer Bar in the ClearSCADA Guide to ViewX and WebX Clients).
2. In the Database Bar, right click on the ‘Site’ Group to display its context sensitive menu, and then select Create New>Modbus - Advanced>SCADAPack Modbus> Digital Input Point.
   A new digital input point is created.
3. Name the digital input point: DI 1

   

4. Display the configuration Form for the 'DI 1' point.
5. Select the Digital Point tab.
6. Select the In Service check box to enable the point.

   

7. Use the browse button feature of the Outstation field to associate the point with the 'ScPack' Outstation that you have already created.

   

8. Set the Address to 10001 (this is the first digital input point address)
9. Set the Retrieval Interval to Interval 1.

   

10. In the States section, set the Severity of State 1 to Alarm and High. This means that when the point changes state to State 1, a high priority alarm will be raised.

    

11. Select the Historic tab.
12. Select the Enabled check box to activate the historic feature.
13. Set the Offset to: S-55S

    This time setting represents the current second minus 55 seconds

14. Set the Interval to: 1M

    This sets the Interval to 1 minute. So the Historic Trend for the point will show 1 minute on the x-axis, with the first time on the x-axis being 55 seconds in the past.

    

15. Save the Point Form and then close it.
16. Make a copy of the 'DI 1' point and paste the copy into the 'Site' Group. The copy is named ‘DI 2’ automatically.

    

17. Display the configuration Form for the 'DI 2' point.
18. On the Digital Point tab, set the Address to 10002.

    

19. Save the Point Form and then close it.

Proceed to Configure Two SCADAPack Modbus Digital Output Points.
