Supported Report Control Block Features
 RptEnabled
 TrgOps
When the gateway is configured to use an IED’s report, after the gateway
establishes a connection with the IED, it turns on RptEnabled. The gateway will
then receive the reports.
TrgOps tells the gateway which internal event will produce the inclusion of a
DATA-SET member onto a report. TrgOps options are:
 Data change (dchg)
 Quality change (qchg)
 Data update (dupd)
 General Interrogation
The reason for inclusion of a piece of data in the report is because the IED is
dependent upon the TrgOps (Trigger Options) in the CID/SCD file.
Report Control Block Services
There are three typical RCB services:
 Report
 GetBRCBValues
 SetBRCBValues
The process starts with the Client issuing RptEna (report enable), as follows:
(This diagram has been taken directly from the IEC 61850 Standard document)
The Report service is used by the BRCB to send reports from the server to the
Client. Transmission is unconfirmed, meaning there is no validation check at the
Client or acknowledement from the Client back to the server.
