PRODUCT SETUP
TxGOOSE1 DatSet
Range: None, DataSet01, DataSet02,...
Default: None
This setting selects the published data set using the UR Setup software designator for the data set. The IEC 61850 name
of the data sets are configured in the Datasets panel, as described later.
An ObjectReference to the data set, which consists of the concatenation of the string "<LDName>/LLN0." and the data
set name, is published in the datSet field of TxGOOSE1 messages and can be used by subscribers to discriminate
TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 DST MAC
Range: any 12 digit hexadecimal number
Default: 01-0C-CD-01-00-00
The value entered sets the Ethernet destination Media Access Control (MAC) address in published TxGOOSE1 messages.
As the standard requires that the address have the multicast bit set TRUE, that is to say the second digit is set to an odd
number, messages transmitted have the multicast bit set TRUE no matter its value in this setting.
The destination MAC address can be used by the network to restrict message delivery to selected devices that need to
receive them, reducing network loading. This address also can be used by hardware in receiving devices to filter out
messages that are of no interest to them, reducing processor burden. Different filtering algorithms are implemented by
different devices. The standard recommends that the algorithm used by hardware of the receiving device be considered
when assigning destination multicast addresses.
Subscribers can use this address to discriminate TxGOOSE1 messages from other GOOSE messages.
TxGOOSE1 VLAN PRIORITY
Range: 0, 1, 2, 3, 4, 5, 6, 7, 5-4, 6-4, 6-5, 7-4, 7-5, 7-6
Default: 4
5
When the value entered is 0, 1, 2, 3, 4, 5, 6, or 7, the User Priority value in the IEEE 802.1Q VLAN tag included in published
TxGOOSE1 messages is set to that value. When one of the two-digit values is entered, the dynamic priority feature is
selected: the first event message has the User Priority value of the first digit, and User Priority is decremented in each
following message until reaching the value of the second digit. For instance, if the selected value is 7-5, then the User
Priority values in successive messages beginning with the message triggered by an event is 7, 6, 5, 5, 5, 5, 5, and so on.
Do not make a dynamic priority selection when standard behavior is required.
Network devices can forward a message with a higher priority value before a message with a lower priority value, which
speeds delivery of high priority messages in heavily loaded networks. The standard recommends that higher priority
messages, such as GOOSE, have priority values in the range of 4 to 7.
TxGOOSE1 VLAN ID
Range: 0 to 4095 in steps of 1
Default: 0
The value entered sets the VID value in the IEEE 802.1Q VLAN tag included in published TxGOOSE1 messages. VID can be
used by network devices to direct messages to only selected devices, reducing network burden. VID values of 0 and 1
are assigned by IEEE 802.1Q to other functions and are not to be used for GOOSE.
TxGOOSE1 ETYPE APPID
Range: 0 to 65535 in steps of 1
Default: 0
The value entered sets the APPID value in published GOOSE messages and can be used by subscribers to discriminate
TxGOOSE1 messages from other GOOSE messages.
The standard reserves the value range 0 to 16383 for GOOSE Type 1 (Fast messages), and reserves the value range
32768 to 41151 for GOOSE Type 1A (Trip messages). Some subscribers can process messages in the Type 1A range
faster than messages in the Type 1 range. The standard reserves the default value (0) to indicate lack of configuration.
The standard strongly recommends unique, source-orientated APPIDs within a given system.
