Define Device Type Tags tab
The Define Device Type Tags tab displays device types and the tags that may be associated each device type. This includes real-time, onboard alarm, control, and reset tags. Most of the fields on this tab are read only (they can be changed on other screens). The following table describes this tab. The tags listed assume that Advanced Properties has been enabled. Not all elements appear on every sub-tab.
Field Name/Valid Entries |
Comments |
---|---|
Device Type Name (Select the device type) |
Each device type includes a different number of tag categories, which also changes the list of tags that display. The device list includes the default device types, and any that have been created for this system. |
Add / Edit button: Click to open the Add / Edit Device Type screen. |
Provides a means of adding new device types and editing custom device types (user-created device types). Also provides a means of adding new custom tags and editing existing tags. |
Locked/Custom icons:
|
Locked icon indicates that the list of selected tags cannot be edited. Custom icon indicates that the device type was created by a user. See Locked and custom icons for complete information. |
Tag groups (left-hand pane) |
|
Select a tag group; the tags included in that group display on the right. |
Each tag belongs to a group. The group is determined when the device is added to the system. For custom tags, this is on the Add/Edit Custom Tags screen. Tags for standard device types are pre-determined and cannot be changed.)
NOTE: If a tag group displays in red copy, there is at least one address that is not valid for the tag to which it is assigned. To correct this issue, click the tag group, ensure that Display Advanced Properties is selected, then scroll down through the tags in the right-hand column. The tags that have invalid addresses will have the “Edit...” displayed in red. Click this field to open the Edit Address page; correct the errors in the address. |
Tag tabs: Real Time, OnBoard Alarm, Control, and Reset |
|
Click a tab to view the tags of that type that are included for the selected device type. If the device type is not locked, you can use the Add/Edit Device Type screen to edit the list of tags. |
|
Tag Description (all tag types)/Display only |
This is the tag name, hard-coded for standard tags. For custom tags: The name is from the Tag Name field in the Add/Edit Custom Tags screen. |
Units/Display only |
Lists the abbreviation, added when creating the engineering unit template. |
IEC Tag Name/Display only |
Tag name that conforms to IEC61850 standard. See About tags for more information. |
Type (Real Time only)/Display only |
Displays the data type chosen when the tag was created. |
Address (not Control tags)/ To edit, click the Edit Address link.
|
Displays the address information for this tag, including elements such as type of register, number of registers, and scaling and bitmasking data. See About tags for a detailed description of address construction. |
Normally Closed (Control tags only)/ Check the box to invert the functionality of the control. See description. |
For a control with one command, writing a 1 to the tag will cause the command to occur. (This option is greyed out.) For a control with two commands that is either static or normally open, writing a 1 to the tag will cause the first command to occur; writing a 0 will cause the second to occur. (Check box not checked.) For a control with two commands that is normally closed, writing a 1 to the tag will cause the second command to occur; writing a 0 will cause the first command to occur. (Check box checked.) |
Edit Addr/Click to display Edit Address screen. (Real Time and Onboard Alarm only) |
Provides the means of changing the elements of an unlocked real-time tag address (for example, the number of registers, their numbers, and whether they are consecutive). See Editing tag addresses for detailed information. |
Register 1/Display only (Real Time tags only) |
This field contains first register used to store this tag. If there are additional registers, they are indicated in the address. The total number of registers is listed in the Num Registers column. This field allows you to verify or change the value of Register 1 without having to open the Edit Address screen. NOTE: If you enter a number that is not compatible with other address settings, you are prompted to go to the Edit Address screen. |
Num Registers/Display only (Real Time tags only) |
Displays the number of registers used by this tag. |
Formatting/Select the format type from the drop-down list (Real Time tags only) |
After you change formatting for a tag and move the cursor to another field, you are asked whether you want to open the Address Editor. If you click No, the format is unchanged; if you click Yes, the Edit Address screen opens for you to enter the appropriate changes for this tag. See Editing tag addresses. |
Scaling Register/View or enter the register number (Real Time tags only) |
This is entered in the Edit Address screen, but it can be edited here. It is the register used to read the value for scaling.
NOTE: If you enter a number that is not compatible with other address settings, you are prompted to go to the Edit Address screen. |
Functional Address/Display only (Real Time, Onboard Alarm, Control, and Reset tags) |
If you have added a functional address for this tag, it displays here. To add or edit this address, use the Edit Functional Address field. |
Typically used for data concentrators, the functional address is a means of entering the individual data points needed to define multiple addresses. Entered as a formula (must be in C#), it will contain the variables the user must enter when the block is instantiated by the I/O Device Manager. A simple example: Address = "T:MV;m:" + (startingpoint + 1005).ToString() + ";L:P:22"
You would then define "startingpoint" when instantiating the profile in the I/O Device Manager. |
|
Tag ID/Display only/Display only |
Assigned by the system when the tag was created. If this is a custom tag, it will be a negative number. |
Category Type (real-time only) Utility Type (real-time only) Statistical Type (real-time only) Quantity (real-time only) |
Each of these types is a real-time filter, added when the tag was created. |
Categorization (onboard alarm only) Subcategorization (onboard alarm only) Alarm Type (onboard alarm only) Alarm Group (onboard alarm only) Alarm Level (onboard alarm only) |
Each of these is an onboard alarm folder, added when the tag was created. |
