2. Application Notes
G1IF4 is applied to provide the following functions:
(1) Interface for connecting protection relays without IEC61850 communication to a
Substation Automation System (SAS) with IEC61850
(2) Gateway in RSM100 communication
To realise the above:
G1IF4 provides two RS485 communication ports. The first is for communication between
G1IF4 and protection relays by IEC60870-5-103 protocol. The second RS485 port, dedicated for
the interface of G1IF4 and TOSHIBA GR relays, is used for monitoring and maintenance by
RSM100.
The Ethernet LAN and TCP/IP protocol are used for communication to station LANs, and its
transmission medium is 100 Base-TX UTP cable or 100 Base-FX optical fibre.
2.1 Interface from/to IEC61850
To connect the protection relays without IEC61850 communication to a SAS with IEC61850 via
G1IF4, the following two methods:
(1) Between IEC60870-5-103 and IEC61850
The G1IF4 is an interface unit which is applied between protection relays (equipped with
IEC60870-5-103 protocol, maximum 10 units) and station LANs belonging to a Substation
Automation System (SAS) as shown in Figure 1.
The main purpose of this unit is to establish a communication link between protection relays and
station LANs (conversion of IEC60870-5-103 to IEC61850 protocol).
The first RS485 port is applied to Master function of IEC60870-5-103 provided with G1IF4. If a
protection relay without IEC61850 but with Slave function of IEC60870-5-103 is connected to
G1IF4, the G1IF4 can convert data between IEC60870-5-103 and IEC61850.

The second port of G1IF4 is applied to RSM communication. The RSM100 is a PC tool for
monitoring and maintenance. Communication between PC and relays is performed by serial or
TCP.
RSM100 is connected to G1IF4 via the RS232C port at the front panel or via the Ethernet port at
the rear panel. Then, the G1IF4 operates as Gateway for RSM100 communication, and the RSM
communication can performed between PC and the relays connected to via the second RS485

2.3 Other Functions
The G1IF4 provides the following functions;
- Time synchronising
- Human interface (LED x 14, RS232C x 1)
- Automatic supervision
2.3.1 Time Synchronising
A time synchronising function between G1IF4 and a master clock is necessary to realize 1ms
resolution for each event and time distribution to protection relays.
GPS (Global Positioning System) provides a master clock and a GPS receiver distributes the
time information to each interface unit via SNTP protocol over UDP/IP.
Normally, the internal clock in the G1IF4 is synchronised with the SNTP server clock and when
the time synchronisation network is interrupted, the internal clock runs locally.
2.3.2 Human Interface
The front panel of the G1IF4 incorporates the following human interfaces:
- Two fixed logic Light Emitting Diodes (LEDs) and twelve configurable logic LEDs
The two fix logic LEDs are used to display the following signals:
- IN SERVICE (Green)
- ALARM (Red)
The colour of the twelve configurable logic LEDs can be selected from among red, green and
yellow respectively. Table 2.3.1 shows the default setting of configurable logic LED. For
details, see Appendix D.

2.3.3 Operation Mode
G1IF4 has two operation modes: on-line mode and test mode.
On-line mode is the normal operation mode. In Test mode, a test flag is added to all transmission
signals from relays.
2.3.4 Automatic Supervision
The automatic monitoring function detects failures that might occur within G1IF4. The
following items are monitored by the automatic supervision function:
- Binary input and output circuits
- Communication circuits for the station LAN, IEC60870-5-103 transmission network
- Processor (Watch Dog timer)
- Memory
- DC power supply circuit
When failures are detected by automatic monitoring, the "ALARM" LED on the front panel is
turned on and also detailed failure information is transmitted to station level control equipment
as event data.
The failure of the interface unit is indicated on the workstation at the station level, and its details
are also displayed on the local HMI.
2.3.4.1 Memory monitoring
The memories are monitored as follows depending on the type of memory:
Random access memory monitoring:
Writes/reads prescribed data and checks the storage function.
Program memory monitoring: Checks the checksum value of the written data.
Setting value monitoring: Checks discrepancy between the setting values stored in
duplicate.

2.3.4.2 Watchdog Timer
A hardware timer which is cleared periodically by software is provided and it is checked that the
software is running normally.
2.3.4.3 DC Supply monitoring
The secondary voltage level of the built-in DC/DC converter is monitored and checked that the
DC voltage is within a prescribed range.
2.3.4.4 PLC Data and IEC61850 Mapping Data Monitoring
Errors in PLC data or IEC61850 mapping data can prevent correct operation. Therefore, the
PLC data and IEC61850 mapping data are monitored and an alarm is issued if errors are
detected.
2.3.4.5 IEC61850 Communication Monitoring
The sending and receiving functions in the Ethernet LAN communication are monitored. The
receiving function is monitored by checking GOOSE message receiving status, and the sending
function is monitored by checking the Ping response to the other party. If a failure is detected, an
alarm is issued.
2.3.4.6 Failure Alarms
When a failure is detected by the automatic supervision, it is followed with LED indication,
external alarms and event recording.

2.3.5 Event Recording
The events shown are recorded with a 1 ms resolution time-tag when the status changes. The
user can set a maximum of 128 recording items, and their status change mode. The event items
can be assigned to a signal number in the signal list. The status change mode is set to “On”(only
recording On transitions) or “On/Off”(recording both On and Off transitions) mode by setting.
The “On/Off”mode events are specified by “Bi-trigger events”setting. If the “Bi-trigger events”
is set to “100”, No.1 to 100 events are “On/Off”mode and No.101 to 128 events are “On”mode.
The name of an event can only be set by RSM100. Maximum 22 characters can be set and can
be viewed on the RSM Setting screen.
The elements necessary for event recording and their setting ranges are shown in the table
below. The default setting of event record is shown in Appendix D.

3.1.1 Signal Processing Module
Microprocessors and communication control circuits for the station LAN are integrated into one
module as a signal processing module. 100Base-TX and 100Base-FX for LAN I/F are provided.
Either of them can be activated by setting.
A 64-bit RISC processor is used to perform dedicated functions in the G1IF4.
3.1.2 Binary Input module
The binary input module, type DIC4, provides 39 photo-coupler circuits for binary input signals.
3.1.3 Binary Output Module
The binary output module, type DIOV1, provides 13 auxiliary relays for binary output signals
including one alarm signal. The power supply circuit (DC to DC converter circuit) is also
mounted in the DIOV1 module.

3.2 Binary Input and Output Signals
3.2.1 Binary input signals
The binary input circuit is provided with a logic level inversion function as shown in Figure
3.2.1. Each input circuit has a binary switch BISW which can be used to select either normal or
inverted operation. This allows the inputs to be driven either by normally open or normally
closed contact. If a signal is not input, the function concerned is disabled. The setting of binary
input can be performed by RSM100.
Further, all binary input functions are programmable by PLC (Programmable Logic Controller)
function.

3.2.2 Binary output signals
The signals shown in the signal list in Appendix C can be assigned to the output relay
individually or in arbitrary combinations. Signals can be combined using either an AND circuit
or OR circuit with 6 gates each as shown in Figure 3.2.2. A 0.2s delayed drop-off timer can be
attached to these assigned signals. The delayed drop-off time is disabled by the [BOTD]. The
output circuit can be configured by RSM100. Appendix D shows the factory default settings.
The relay failure contact closes the contact when a relay defect or abnormality in the DC power
supply circuit is detected.

3.3 PLC (Programmable Logic Controller) Function
G1IF4 is provided with a PLC function allowing user-configurable sequence logics on binary
signals. The sequence logics with timers, flip-flops, AND, OR, XOR, NOT logics, etc. can be

elements or binary circuits.
Configurable binary inputs, binary outputs and LEDs are programmed by the PLC function.
Temporary signals are provided for complicated logics or for using a user-configured signal in
many logic sequences.
For PLC tool, refer to PLC tool instruction manual.
