GE SR750/760 Relay Tutorials - Part 5: Link XRIO Parameters Into RIO Device Function In The Test Object

Welcome to the fifth part of GE SR750/760 Relay Tutorial series. In this tutorial, I will show you how to link XRIO parameters into RIO Device Function, writing formula in the script function editor, I will show you how to make this test plan/routine flexible during relay testing and also, other stuff.

Device function block contains general information and settings such as:

the test object's name or description and its manufacturer *
the test object's device type and address *
the test object's serial or model number *
additional information to identify the test object *
power system nominal values *
residual factors *
overload detection sensitivity *
limits *
and others *

* Reference from Omicron Test Universe help manual

Open the test document that been created from the previous tutorial (Part 3). Make sure that the advanced view is checked in the view menu to enable the linking in RIO function parameters.

Go to device nominal values block under the RIO block then link f nom parameter to Frequency Nominal. Right click on to f nom formula then click add reference. In the insert formula reference dialog box select the Frequency Nominal parameter under XRIO » Power System block then click OK button.

GE SR750/760 » RIO » Device
Parameter	Formula
f nom	`FREQUENCY_NOMINAL`
Formula ID's	Path
`FREQUENCY_NOMINAL`	GE SR750/760 » XRIO » Power System » Frequency Nominal

Because we want to make this test plan/routine to be flexible, we have to create a test controller for voltage and current selection. To do that, add new block under GE SR750/760 block then set the following parameters

GE SR750/760
Test Controller
ID	TEST_CONTROLLER
Name	Test Controller

Then move the test controller block to the top by right click on it and selecting move up or by doing shortcut key Ctrl + U until it reach the top.

Add another block under GE SR750/760 > Test Controller block and set the following

GE SR750/760 > Test Controller
Voltage/Current Controller
ID	VOLTAGE_CURRENT_CONTROLLER
Name	Voltage/Current Controller

Once that completed, add two parameters under the Test Controller > Voltage/Current Controller block and set the following parameter's details

GE SR750/760 > Test Controller > Voltage/Current Controller

Voltage Controller

VOLTAGE_CONTROLLER

Name

Voltage Controller

Data Type

Enumeration

Enumeration Values
ID	Name
BUS_VT	Bus VT
LINE_VT	Line VT

Value

Current Controller

CURRENT_CONTROLLER

Name

Current Controller

Data Type

Enumeration

Enumeration Values
ID	Name
PHASE_CT	Phase CT
GROUND_CT	Ground CT
SGROUND_CT	Sensitive Ground CT

Value

Phase CT

Once that completed, that should be looked like the image below.

Now, back to the device function nominal values block , let's link the current and voltage using the voltage and current controller. On the V nom parameter, we're going to link the Bus VT and the Line VT using iif() command. Enter and link the formulas listed below.

GE SR750/760 » RIO » Device
Parameter	Formula
V nom	`iif(VOLTAGE_CONTROLLER=BUS_VT, BUS_VT_SECONDARY, LINE_VT_SECONDARY)`
V prim L-L	`iif(VOLTAGE_CONTROLLER=BUS_VT, BUS_VT_PRIMARY, LINE_VT_PRIMARY)`
Formula ID's	Path
`VOLTAGE_CONTROLLER`	GE SR750/760 » Test Controller » Voltage/Current Controller » Voltage Controller
`BUS_VT`	GE SR750/760 » Test Controller » Voltage/Current Controller » Voltage Controller » Bus VT
`BUS_VT_SECONDARY`	GE SR750/760 » XRIO » Power System » Bus VT Secondary
`LINE_VT_SECONDARY`	GE SR750/760 » XRIO » Power System » Line VT Secondary
`BUS_VT_PRIMARY`	GE SR750/760 » XRIO » Power System » Bus VT Primary
`LINE_VT_PRIMARY`	GE SR750/760 » XRIO » Power System » Line VT Primary

The results should be like in the image below.

Let's link the I prim and In. Enter and link the following formula listed below.

GE SR750/760 » RIO » Device
Parameter	Formula
In	`iif(CURRENT_CONTROLLER=PHASE_CT, PHASE_CT_SECONDARY, iif(CURRENT_CONTROLLER=GROUND_CT, GROUND_CT_SECONDARY, SG_CT_SECONDARY)`
I prim	`iif(CURRENT_CONTROLLER=PHASE_CT, PHASE_CT_PRIMARY, iif(CURRENT_CONTROLLER=GROUND_CT, GROUND_CT_PRIMARY, SG_CT_PRIMARY)`
Formula ID's	Path
`CURRENT_CONTROLLER`	GE SR750/760 » Test Controller » Voltage/Current Controller » Current Controller
`PHASE_CT`	GE SR750/760 » Test Controller » Voltage/Current Controller » Current Controller » Phase CT
`GROUND_CT`	GE SR750/760 » Test Controller » Voltage/Current Controller » Current Controller » Ground CT
`PHASE_CT_SECONDARY`	GE SR750/760 » XRIO » Power System » Phase CT Secondary
`GROUND_CT_SECONDARY`	GE SR750/760 » XRIO » Power System » Ground CT Secondary
`SG_CT_SECONDARY`	GE SR750/760 » XRIO » Power System » Sensitive Ground CT Secondary
`PHASE_CT_PRIMARY`	GE SR750/760 » XRIO » Power System » Phase CT Primary
`GROUND_CT_PRIMARY`	GE SR750/760 » XRIO » Power System » Ground CT Primary
`SG_CT_PRIMARY`	GE SR750/760 » XRIO » Power System » Sensitive Ground CT Primary

The results should be looked like the image below

As you can see, the In value is zero because we haven't set yet their values in the XRIO > Power System block . I'm going to write formula for that to parse the nominal current in relay order code. Copy the code below and paste it to the Script Function editor.

Function GetNominalCurrent(OrderCode As String, PGS As String) As Double
    If PGS = "P" Then
        If OrderCode.Contains("P5") Then
            Return 5
        Else
            Return 1
        End If
    ElseIf PGS = "G" Then
        If OrderCode.Contains("G5") Then
            Return 5
        Else
            Return 1
        End If
    Else
        If OrderCode.Contains("S5") Then
            Return 5
        Else
            Return 1
        End If
    End If
End Function

Let's use that formula to get those nominal current. Go back to Power System block under the XRIO block , type the following formula for each parameter listed below and link the ORDER_CODE parameter to parse.

GE SR750/760 » XRIO » Power System
Parameter	Formula
Phase CT Secondary	`GetNominalCurrent(ORDER_CODE, "P")`
Ground CT Secondary	`GetNominalCurrent(ORDER_CODE, "G")`
Sensitive Ground CT Secondary	`GetNominalCurrent(ORDER_CODE, "S")`
Formula ID's	Path
`ORDER_CODE`	GE SR750/760 » Relay Parameters » Device Definition » Order Code
`"P" "G" "S"`	String selector. P - primary, G - ground, S or " " - sensitive ground

The results should be the same in the image below.

Now, let's make additional relay information blocks and parameters to link in the RIO Device Function. First, add new block under the GE SR750/760 block then set the following block details below.

» GE SR750/760
Additional Information
ID	ADDITIONAL_INFORMATION
Name	Additional Information

This block will be inserted in the bottom list so move it up right next to Relay Parameters. Then add another block under this Additional Information block and set the following block details below.

» GE SR750/760 » Additional Information
Relay Information
ID	RELAY_INFORMATION
Name	Relay Information

Add ten string parameters into Relay Information block under the GE SR750/760 » Additional Information block then set the following parameter details below.

» GE SR750/760 » Additional Information » Relay Information

Link the Order Code and Relay Serial Number from Device Definition parameter into Relay Information Relay Model and Serial Number receptively. The results should be looked like in the image below.

GE SR750/760 » Additional Information » Relay Information
Parameter	Formula
Relay Model	`"SR" & left(ORDER_CODE, 3)`
Serial Number	`SERIAL_NUMBER`
Formula ID's	Path
`ORDER_CODE`	GE SR750/760 » Relay Parameters » Device Definition » Order Code
`SERIAL_NUMBER`	GE SR750/760 » Relay Parameters » Device Definition » Serial Number

Let's link those parameters into RIO Device function nameplate and location. Link the following parameters in the table below

GE SR750/760 » RIO » Device » Name Plate
Parameter	Formula
Device name	`RELAY_MODEL`
Manufacturer	`RELAY_MANUFACTURER`
Device type	`DEVICE_TYPE`

`BAY_NAME`	GE SR750/760 » Additional Information » Relay Information » Circuit Name
`BAY_ADDRESS`	GE SR750/760 » Additional Information » Relay Information » Circuit Address

The results should be looked like in the images below

That's it for now. In the next part, I will show you adding Overcurrent function and linking parameters onto it.

Summary

In this tutorial, we learned adding more blocks and parameters, writing formula in the script function editor, using script function formulas in the the parameter's formula, linking parameters with condition to make the test plan/routine flexible during testing.

See you next time.
