00:00:22,445 --> 00:00:28,973
After identifying the problems with “RIO” files, “OMICRON” company decided to implement a new idea.

2
00:00:29,115 --> 00:00:33,669
According to this idea, a file format named “XRIO” was created

3
00:00:33,763 --> 00:00:38,531
in which a section named “Relay parameter section” was designed for every relay

4
00:00:38,556 --> 00:00:44,625
and all relay menus were arranged and addressed exactly the same way as in the relay software.

5
00:00:44,650 --> 00:00:53,945
Another section -of this file- is “Additional information” which includes -that- necessary information which is not available in the relay software and should be read from its catalogue.

6
00:00:53,970 --> 00:00:58,500
For example, if you click on “General information” tree diagram on “General” block,

7
00:00:58,525 --> 00:01:07,449
you can see that “AREVA” is recorded as the “Manufacturer” which is not available in the relay menu but is necessary to complete the device information.

8
00:01:07,474 --> 00:01:13,290
The important point in getting familiar with “XRio” is that you should know how “XRio” blocks are defined.

9
00:01:13,315 --> 00:01:18,211
For example, in “Relay Parameter Section” tree diagram and in the “SYSTEM DATA” block,

10
00:01:18,236 --> 00:01:23,530
, the “Language” parameter is of “Enumeration” type and its value is defined as “English”.

11
00:01:23,555 --> 00:01:31,187
Now, if the “XRio” file of this relay is opened in “Notepad++”, after opening the “Custom” tag, you can see the “Setting” block,

12
00:01:31,212 --> 00:01:45,661
“ID_00”  block and parameter with “id=ID_0001”. The “Name”, “ForeignId” and “DataType” of this parameter are “Language”, “0001” and “Enumeration” respectively.

13
00:01:45,686 --> 00:01:51,325
In the “EnumList” tag, you can see that, four languages including English, French,

14
00:01:51,350 --> 00:01:57,372
German and Spanish are available as “Value” for this section and in this case “English” has been selected.

15
00:01:57,397 --> 00:02:05,419
Now, if you return to the “Vebko AMPro Test” software, you can see the exact same information in the “Test Object” section.

16
00:02:05,444 --> 00:02:13,583
This means that by double-clicking on “Relay Parameter Section” in the tree diagram you can see that its “ID” is defined as “SETTINGS”;

17
00:02:13,608 --> 00:02:21,255
then by double-clicking on the “System Data” block you can see that its “ForeginID” is defined as “ID_00”.

18
00:02:21,280 --> 00:02:30,693
In its parameters table, you can see that “Enumeration” is defined as “Type” for the parameters named “Language” and “ForeignID:0001”.

19
00:02:30,718 --> 00:02:35,380
Also, in the “Value” field there are four languages of English, French,

20
00:02:35,405 --> 00:02:41,919
German and Spanish available where “English” is selected by default in accordance with the displayed codes.

21
00:02:41,944 --> 00:02:48,685
After an “XRio” file is loaded, the necessary settings and information of the “Rio” section are completed accordingly

22
00:02:48,710 --> 00:02:55,482
and the cells whose information is dependent on a formula or parameter from the “XRio” file, are turned purple.

23
00:02:55,507 --> 00:03:04,161
For example, the value of nominal frequency in the “Nominal Values” block is defined according to a formula from the “Formula” column

24
00:03:04,186 --> 00:03:15,318
 and if this value is modified manually,the color of the cell changes to pink which means that there is no more a connection between the value of this cell and the formula defined for it.

25
00:03:15,343 --> 00:03:21,732
-To make the value of this cell again dependent on the formula, right-click on it and select "Recalculate formula"-.

26
00:03:21,757 --> 00:03:27,153
To find out about that how the nominal frequency (with purple color) is defined, first, you should select it

27
00:03:27,178 --> 00:03:33,958
and then click on the “Reference Map” icon to view a map of the parameters to which the frequency is dependent.

28
00:03:33,983 --> 00:03:36,982
By clicking on any of the boxes in this section,

29
00:03:37,007 --> 00:03:44,614
the parameter that affects the final value of the frequency is displayed which, in here, the frequency is taken from “Fnom”.

30
00:03:44,639 --> 00:03:50,528
The value of “Fnom” parameter is, itself, based on a formula and is dependent on another parameter

31
00:03:50,553 --> 00:03:55,396
which by clicking on the “Map” box,you can see that a parameter named “Frequency” is used.

32
00:03:55,421 --> 00:03:59,802
This means that, since “50” is set as the value for “Nominal Values”,

33
00:03:59,827 --> 00:04:11,021
the value for “Fnom” is, according to its formula, “50” too and finally the amount of nominal frequency in “Nominal Values”, according to the defined relation, is “50” Hz.

34
00:04:11,046 --> 00:04:14,803
Now, if you open the “XRio” file in “Notepad++”,

35
00:04:14,828 --> 00:04:21,732
you can view the path that was used to find the affective parameters in the software in the codes of this file.

36
00:04:21,757 --> 00:04:29,576
Follow the path “Rio->Device->Nominal Value” in the codes of this file until you find “Fnom”.

37
00:04:29,601 --> 00:04:37,943
You can see that this parameter has a value of “50” but has a “ValueRefList” whose affective parameters are in the mentioned “Reference”.

38
00:04:37,968 --> 00:04:47,076
To find this parameter, you need to follow the mentioned path which is “CUSTOM.RIOPLUS.POWERSYSTEMPARAMETERS.FNOM”.

39
00:04:47,187 --> 00:04:53,066
You can see that type, value, unit and formula of this parameter are mentioned in this path.

40
00:04:53,091 --> 00:05:03,784
It is mentioned in the formula of this section that if “ID_0009=FIFTY”, the value for this parameter is 50, otherwise it equals 60.

41
00:05:03,809 --> 00:05:09,871
It is also necessary to define the two phrases “ID_0009” and “FIFTY”.

42
00:05:09,896 --> 00:05:18,340
To view the definition of these two phrases, you need to open the “ValueRefList” tag. there is a “Value reference list” mentioned for each of these phrases.

43
00:05:18,435 --> 00:05:19,589
You can see that

44
00:05:19,614 --> 00:05:23,605
 there is a “Value reference list” mentioned for each of these phrases.

45
00:05:23,630 --> 00:05:35,588
For “ID_0009” you should follow the path “CUSTOM.SETTINGS.ID_00” and find the value of “ID_0009”.

46
00:05:35,613 --> 00:05:44,480
In this case, you can see that this parameter is named “Frequencey” and its “ForeginID:0009” and is of the “Enumeration” type.

47
00:05:44,505 --> 00:05:51,316
Also, in the “EnumList” tag, “50” Hz is defined for “FIFTY” while “60” Hz is defined for “SIXTY”.

48
00:05:51,341 --> 00:05:57,809
The explained case is a very simple example of defining parameters values of a relay for test.

49
00:05:57,834 --> 00:06:04,394
An another example, it is possible to select and open the “ZONE P GROUND” block

50
00:06:04,419 --> 00:06:10,973
from the tree diagram of the distance block and then click on “M3” to view its parameters in the table.

51
00:06:10,998 --> 00:06:15,341
If the “Reference Map” of the “Angle” parameter is opened, you can see that...

52
00:06:15,366 --> 00:06:18,593
that this parameter is dependent on many other parameters

53
00:06:18,618 --> 00:06:25,326
By clicking on any of the available boxes in this “Reference Map”, the given parameter for address is displayed.
