Part 5: Link XRIO Parameters Into RIO Device Function In The Test Object

GE SR750/760 Relay Tutorials

Open the test document that been created from the previous tutorial (Part 3).

When the Omicron Control Center document is open, select the Hardware Configuration then go to Insert tab in the ribbon menu. In the Insert tab, click the Group button to insert a new folder group under the Hardware Configuration. Right click on the new group and select properties. In the properties dialog box, set the title to Phase Current.

Select the Phase Current group and go to Insert tab then click Group button. Right click on it the select properties. In the properties dialog box, set the title to Phase Time Overcurrent 1.

Select the Phase Time Overcurrent 1 group and go to Insert tab then click Test Module button. The Insert Test Module dialog box will popup, select create new Overcurrent then click OK. Right click on it the select properties. In the properties dialog box, set the title to Phase Time Overcurrent 1 Trip Time Test - R. Then open and close the Overcurrent test module to generate the required RIO functions in the test object.

Now, open the test object and make sure that the advanced view is checked in the view menu to enable the linking in RIO function parameters.

As you can see, Overcurrent and CB Configuration function blocks are added. Now, add new block under under GE SR750/760 » Relay Parameters » Protection and set the following properties.

GE SR750/760 » Relay Parameters » Protection
Phase Current
ID	PHASE_CURRENT
Name	Phase Current

Under Phase Current block, add new block then set the following properties

GE SR750/760 » Relay Parameters » Protection » Phase Current
Phase Time Overcurrent 1
ID	PTOC1
Name	Phase Time Overcurrent 1

Open the EnerVista 750/760 Setup, open the setting file and go to Protection » Phase Current » Phase Time Overcurrent 1. There are twelve parameter settings and add those parameter settings in the Omicron Test Object. To do that, enter the following parameter details below.

Rename the third block to Phase Time Overcurrent Active and set the ID to PTOC_ACTIVE, then add new parameter and set the following. Phase Time Overcurrent 1 and 2 will be link here using the conditional formula iff(). This formula is commonly used to compare two parameters and it will give a certain result.

In this tutorial you've learned adding multiple blocks, adding multiple parameters, linking parameters to other parameters, linking parameters with conditional formula like iff(), Inserting test module to test document (OCC)

In the tutorial, I will show you how to link XRIO parameters in the RIO function module. I will show you how to use this test plan during the testing of the relay.

See you next time.
