SVCB attribute |
Description |
|---|---|
|
SVID |
A SVCB-specific string. The default value is <IedName>MU0x. Maximum SVID length is 129 characters, as defined in IEC 61850-9-2 Ed 2.1. |
|
Multicast address |
A multicast addressing scheme is used when sending sampled values messages. A multicast address can be shared by several sending devices or it can be IED specific. To keep the multicast message filtering of the devices working, it is recommended to use unique multicast addresses. |
|
SVCB name |
The name of the SVCB structure seen by the IEC 61850/MMS client |
|
Data set |
Data sent in sampled values messages to the network. Default data set PhsMeas1 is created for 9-2LE sender. PhsMeas2 data set is created as default for IEC 61869-9 compliant sender. In 9-2LE sender mode the PhsMeas data set should not be modified. In IEC 61869-9 compliant mode the data set content must be configured manually. |
|
ConfRev |
ConfRev increases when the referenced data set is modified. Both the sampled values sender and the receiver must have the same ConfRev value. This ensures that both IEDs have the same configuration level in the substation configuration. ConfRev usage is done automatically by the tools. If the latest system configuration is not downloaded into all required IEDs, the configuration revision may differ between the receiver and sender. |
|
MAC Address |
Multicast MAC address to which the sampled values data is sent. The receiving IED filters the frames and starts to process them if a multicast address is defined in the configuration. It is recommended to have one unique multicast address per SVCB. The address range for sampled values multicast addresses is 01-0C- CD-04-00-00...01-0C-CD-04-01-FF. |
|
App ID |
Unique HEX value application identifier for sending the SVCB within the system. It identifies the purpose of a data set. The value range for sampled values is 0x4000...0x7FFF. |
|
VLAN-ID |
Used if the Ethernet switches in a station bus support VLAN. If static VLAN identifiers are defined, it also affects the switch port configuration. Value “000” indicates a non-configured VLAN and switches do not filter these messages on a port basis. This is recommended if there is no need to split the logical network. The VLAN identifier is a three-character HEX value with range 000...FFF. The recommended values are 2...1001. |
|
VLAN Priority |
Used in networks supporting VLANs. The priority is used with network switches. The default value for sampled values is “4” and the value range is 0...7. |
|
Sample Rate |
Sample rate in units defined by the sampling mode |
|
NoAsdu |
Number of ASDUs, which are concatenated into one APDU |
|
Master Clock ID |
If selected SV frame contains the grandmaster id of the SMV sender. That is, the IEC 61850-9-2 option "gmIdentity". |
Configuring unsupported SV control block attributes results in IRF warning "SMV warning" in the relay, and SMV stream sender not being activated.
