The project was carried out at the Jambi fuel terminal on the ATG to TMS communication system. 2. The main device replaced was the Gateway ATG ECU-1051 Advantech. 3. The gateway is the communication interface between the field ATG devices and the TMS application. 4. The main aim was to restore tank data communication to the TMS application. 5. Additional work covered installing communication protection for RS485 Modbus and LAN Ethernet. **Challenges** 1. Data communication between the ATG and the TMS was faulty or unstable. 2. Tank data could not be read in real time in the TMS application. 3. The gateway was exposed to electrical disturbance from the field communication lines. 4. The RS485 Modbus and LAN Ethernet lines could be hit by voltage surges from lightning or electrical short circuits. 5. A gateway failure could cut the data link from the ATG to the monitoring system. **Solutions** 1. Replaced the spare part Gateway ATG ECU-1051 Advantech. 2. Reconfigured the gateway so ATG to TMS communication returned to normal. 3. Checked the RS485 Modbus connection from the ATG to the gateway. 4. Checked the LAN Ethernet connection from the gateway to the TMS application network. 5. Added an RS485 Modbus surge protector to protect the serial communication line. 6. Added a LAN Ethernet surge protector to protect the network communication line. 7. Tested data communication to confirm ATG data could be read in the TMS application again. **Lessons learned** 1. The communication gateway is a critical device in the ATG-TMS data link. 2. A gateway fault directly affects the availability of tank data in the TMS application. 3. Communication line protection should be installed from the start, especially in areas prone to lightning or electrical disturbance. 4. RS485 Modbus and LAN Ethernet lines need surge protection to lower the risk of device damage. 5. After a device is replaced, an end-to-end communication test from the ATG to the TMS application is mandatory. ## Contact - Company: PT Citia Engineering Indonesia - Email: services@citiaengineering.com - Telephone: +62 21 278 20286 - Office: Jl.
