The user must pay attention when configuring the function type and information number
of the different points, because they must be unique. There is no mechanism in the
EnerVista 8 Series Setup software or the front panel HMI to detect duplication of the
information index.
The IEC 60870-5-103 point lists always begin with point 0 and end at the first "Off" value.
Since IEC 60870-5-103 point lists must be in one continuous block, any points assigned
after the first "Off" point are ignored.
The optional communications processor supports both the IEC61850 GOOSE and IEC
61850 MMS Server service as per IEC 61850 standard Ed. 2. The GOOSE messaging service
provides the 845 unit the ability to Publish/Subscribe Digital Input Status and it's Quality
and Timestamp to/from other IEDs with supporting GOOSE messaging service, while the
server support allows remote control center, RTU/Gateway, local HMI or other client role
devices access to the relay for monitoring and control. The configuration of IEC61850
services is accomplished using the 845 configuration software, EnerVista 8 Series
Setup software. A rebooting MUST be done before any changes made take affect.
The IEC 61850 Configurator
The 845 relay supports the IEC 61850 protocol which is identified by order code option "2A"
or "2E".
The IEC 61850 configurator is found in both the online and offline section of the EnerVista
8 Series Setup software for configuring the online 845 relay and offline 845 settings file
respectively.
IEC 61850 Configurator Details
The IEC61850 Configurator allows the user to edit all sections of the IEC61850 CID and ICD
file. The user cannot perform any other operations in the EnerVista 8 Series Setup software
if the IEC 61850 Configurator is open. The user must close the IEC61850 session to perform
other operations in the EnerVista software.
The IEC 61850 configurator consists of five sections:
• ICD/CID
• Settings
• Reports
• Goose Reception
