c.
They are stored (up to the specified limit for each server) in case communication
between server and client fails.
d.
The client asks for buffered reports only if it detects a connection failure or lost
report, otherwise the BRCBs act like URCBs and the server sends a block immediately
after a value or quality change.
Trigger options
a.
In an RCB, the data are pushed by the server on a trigger. The trigger supports several
options:
1.
TrgOps data-change: Data value change
2.
TrgOps quality-change: Quality change
3.
TrgOps data-update: Timestamp change
4.
TrgOps Integrity: Minimum every bufTm (bufTm is define in the RCB)
5.
TrgOps general-interrogation: On request by the client (GI)
b.
These options are set by the server, if the “Use preconfigured TrgOps” in “IEC 61850
Configurator”
is set. Otherwise the defined values in the client configuration are
used. For more information refer to section 3.3.5 Use Preconfigured TrgOps
3.4.2
Configuring URCBs
You can use either or both of the options below for configuring URCBs in the ECM850:
a.
Configuring URCB - Indirect Method : Refer Configuring URCB - Indirect Method
b.
Configuring URCB
–
Direct Method : Refer
Configuring URCB - Indirect Method
The RCB assignment can be done automatically by the IEC 61850 client driver in ECM850; in
that case the maximum of URCBs can be set in the configuration for each IED.
The URCBs are accessed in an order related to their importance. the more variables related
to a URCB that are used, the higher the priority for accessing the URCB.
The ECM850 browses all URCBs and their corresponding DATASETs. The driver will prioritize
connections to the URCBs that contain the most data to be read by the client. Other data
will be read by polling according to the Polling time configured.
Refer to the screenshot below and check the server parameter
–
Maximum URCBs. This
value can be increased for this feature. However, this is an indirect way of handling reports.
