4. LED Indicators
PWR: Power – steady = OK
RUN: Module – flashing = running normally
ETH: Ethernet – flashing = link/activity
SER: Serial (103) – flashing = active communication
ERR: Fault – ON = configuration/communication error
5. Installation & Wiring
Mount gateway on DIN rail in cabinet.
Connect 24 VDC power (observe polarity).
Connect Ethernet cable to RJ45 for 104 SCADA connection.
Wire serial port to 103 devices (RS‑485 recommended for multi‑drop).
Set network parameters (IP, subnet, gateway) via configuration software.
Configure 104 server parameters (ASDU address, cyclic intervals).
Configure 103 master parameters (slave addresses, baud rate, polling list).
Map 104 data points/commands to 103 data objects.
Download configuration; verify LED status and data exchange.
6. Data Mapping
Map 104: single points, double points, measured values, setpoints, commands
Map 103: information elements, measured values, commands, disturbance records
Time synchronization: 104 time distributed to 103 devices
Configurable fault states: hold last value or set to zero on timeout
7. Typical Applications
Power utility SCADA: connect 104‑based control centers to 103‑based protection relays
Substation automation: integrate legacy 103 IEDs into modern 104 networks
Oil & gas, water treatment: bridge 104 SCADA and 103 field devices
Renewable energy plants: protocol conversion for grid‑side communication
8. Safety Notes
Disconnect power before installation/wiring.
Use shielded cables for both Ethernet and serial.
Do not exceed voltage and temperature ratings.
Terminate RS‑485 bus at both ends.
Configuration must be performed by qualified personnel.
