PRODUCT SETUP
When the Ok button is clicked, the entered values for Product LD inst name and Functional ldName are checked for
uniqueness within the UR, and they are updated in the pane.
The settings are explained as follows, where <iedName> is a syntactic variable representing the present value of the IED
NAME setting. When adding or editing a logical device entry, these are the fields that need to be completed.
Customized logical nodes are not saved in the URS file.
Product LD inst name
5
Range: 1 to 64 VisibleString characters
Default: as per the following table
Each logical device has this setting. The value is fixed at "Master" in the first logical device and configurable in all others.
Valid characters are upper and lowercase letters, digits, and the underscore (_) character. The entered value sets the
logical device inst name. Each logical device inst name is required to be unique within the device, and it cannot be blank.
Also, if the corresponding functional ldName setting is blank, the concatenation of the IED name and the logical device
inst name must form an LDName that is unique within the network for proper operation. It is recommended that the
length of the IED NAME plus the length of this setting be not greater than 64 to respect the requirements of IEC 61850 7
2:2010 22.2 for LDName.
The factory default configuration is for six logical devices with Product LD inst name settings and logical node
assignments as per the following table.

This is the root logical device.
To comply with IEC 61850 7 1 Ed2 clause 6.4.5.1, all group L logical nodes (logical nodes with class names
begin with "L"), except LLN0, belonging to this IED are in this logical device.
