The logical devices in UR series devices are arranged in a hierarchy, with the Master logical device as the root logical
device and all other implemented logical devices direct descendants. The effect of this arrangement is that the scope of
certain items in the Master logical device includes the entire hierarchy, as outlined in the following table.
Table 3-10: Master/root data objects and attributes
3.5.1.1 Event recorder (EvtRcd)
See LLN0.
3.5.1.2 Logical node zero (LLN0)
LLN0 is instantiated in all UR series devices.
The following is specific to the Master logical device. LLN0 in other logical devices have different content.
Table 3-11: Logical node zero data objects
Name Description
Mod The controllable data object Mod controls the test mode selection of the UR device and thus affects the status of Beh
data objects and of q data attributes
configRev The configurable data attribute configRev has a scope that includes the entire UR device.
Modify this attribute whenever any logical node gets a new semantic use, for example an instance of a CSWI is now
serving a different physical switch or an instance of a logical node PDIS is now used for another zone.
Also modify this attribute whenever any data object gets a new semantic use, for example the use of ConInGGIO.Ind1
changes from "Door open" to "Fire alarm".
As it is not in general possible for the device to know that such a change has occurred, you need to revise the value of
configRev.
paramRev The configurable data attribute paramRev has a scope that includes the entire device, and thus is modified whenever
any setting in the device changes. The UR increments the value of paramRev by one whenever a setting change occurs
by any means (front panel, Modbus, or MMS) other than by SCL file download. Incrementing occurs whether or not the
setting is represented in the information model. When a UR device or EnerVista UR Setup accepts an SCL file, paramRev
is set to the value in that SCL file. When EnerVista UR Setup changes one or more settings, and prepares an SCL file, it
increments paramRev to the next higher multiple of 10 000.
SCGB The setting group control block in the Master logical device has a scope that includes the entire device due to the UR
logical device hierarchy. That is to say, all grouped settings are controlled form this one control block.
