CHAPTER 4: SETPOINTS DEVICE
845 TRANSFORMER PROTECTION SYSTEM – INSTRUCTION MANUAL 4–45
These 96 Single Points and 32 Measured Values are also sent as a response to a General
Interrogation.
The Integrated Totals (M_IT) has its own Counter Group 1, and it is sent as a response to a
General Request Counter.
IEC 60870-5-103 The point map for the 103 is different from the one shared by the IEC104 and DNP
protocols. IEC 60870-5-103 serial communications protocol is supported on the rear RS485
port only.
The DNP, 103 and Modbus can not be enabled simultaneously. Only one instance of
DNP3.0, IEC 103 or Modbus can run on the RS485 serial port.

All binary inputs are configured from FlexLogic operands. For a complete list, see Format
Code FC142.
FAST PATH:
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.
FAST PATH:
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.
IEC 61850 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 its 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 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 and offline 845 settings file
respectively.
