5. Installation & Wiring

1. Mount on DIN rail in cabinet.

2. Connect 24 VDC to power terminals (redundant recommended).

3. Connect Ethernet cable to RJ45 for IEC 60870-5-104.

4. Connect PROFIBUS cable to DB9; use standard PROFIBUS pinout.

5. Set PROFIBUS slave address and baud rate via terminal/web UI.

6. Configure 104 IP, subnet, and data mapping.

7. Save config, reboot, verify communication.

6. Communication Functions

1. 104 → PROFIBUS: Write 104 commands/data to PROFIBUS slave outputs.

2. PROFIBUS → 104: Read slave inputs, timestamp, and send as 104 events.

3. Time Sync: 104 time sync to PROFIBUS (timestamped data).

4. Redundant 104: Dual client connections with automatic failover.

5. Data Integrity: Cyclic I/O with watchdog and error handling.

7. Applications

1. Power & Utility: Connect SCADA (104) to factory PROFIBUS DP I/O/drives.

2. Substation Automation: Integrate protection relays and PROFIBUS devices.

3. Legacy Integration: Bridge older PROFIBUS systems to modern 104 SCADA.

4. Process Control: Water treatment, power plants, and industrial automation.

5. Smart Grid: Enable 104‑based monitoring/control of PROFIBUS equipment.

8. Safety Notes

1. Power Off: Wire only when power is disconnected.

2. Cables: Use shielded cables for both Ethernet and PROFIBUS.

3. Grounding: Properly ground gateway and devices to avoid ESD.

4. Bus Parameters: Match baud rate and slave address on PROFIBUS bus.

5. Environment: Avoid direct sunlight, moisture, and strong EMI sources.
