# MOV Tidak Terbaca di SCADA? Practical Troubleshooting: From Gateway to Field Device

Citia Micro-Webinar #03, Jumat 21 November 2026 pukul 14.00 WIB via Microsoft Teams: studi kasus gratis ±20 menit tentang MOV yang tidak terbaca di SCADA.

## Topik yang dibahas

- Studi kasus MOV: sebagian perangkat terbaca, sebagian tidak
- Arsitektur komunikasi MOV, RS-485, Gateway, SCADA
- Langkah troubleshooting: power, wiring, address, polling, command & feedback
- Lesson learned dan checklist diagnosis

Ringkasnya

Motor-operated valve (MOV) adalah valve yang digerakkan aktuator listrik, sehingga ruang kontrol bisa membuka, menutup, dan menghentikannya tanpa mengirim orang ke lapangan. Aktuator itu juga mengirim balik status: posisi valve, OPEN atau CLOSE, mode Local atau Remote, kondisi thermal, torque, dan fault.

Feedback itu sampai ke SCADA lewat jalur serial, umumnya RS-485, melalui gateway yang membaca (polling) tiap aktuator berdasarkan address. Kalau hanya sebagian MOV yang muncul di SCADA, perangkat yang menjawab sudah membuktikan bahwa SCADA dan sebagian jalur masih hidup. Tugasnya mencari di titik mana perangkat yang diam itu terputus.

Micro-Webinar #03 mengambil kasus itu dan menelusuri jalur dari gateway sampai perangkat lapangan. Sesinya singkat, sekitar 20 menit, berangkat dari satu masalah lapangan dan checklist yang lahir darinya.

Sebagai bekal, halaman proyek komunikasi MOV Citia di terminal BBM Jambi menggambarkan jalur dengan bentuk yang sama, dan panduan troubleshooting Modbus RS-485 , Modbus , serta SCADA menjelaskan protokol dan sistem di sekitarnya.

- Citia Micro-Webinar #03 berlangsung online via Microsoft Teams pada Jumat, 21 November 2026 pukul 14.00 WIB, sekitar 20 menit, gratis.
- Kasusnya sekelompok motor-operated valve (MOV) yang sebagian terbaca di SCADA dan sebagian tidak.
- Sesi ini menelusuri jalur MOV, RS-485, gateway, SCADA dan memeriksa power, wiring, address, polling, serta command dan feedback.

- 21 Nov 2026 Tanggal Jumat
- 14.00 WIB Pukul Sekitar 20 menit
- Teams Platform Online via Microsoft Teams
- Free Biaya RSVP lewat siTia
- Aktuator MOV: Mengirim posisi, OPEN/CLOSE, Local/Remote, thermal, torque, dan fault.
- Jalur RS-485: Pada proyek MOV Jambi, jalur ini melewati surge protection device (SPD) lebih dulu.
- Gateway: Membaca tiap MOV berdasarkan address, register, function code, baud rate, dan parity.
- SCADA: Menampilkan data MOV sebagai tag dan mengirim perintah OPEN, CLOSE, dan STOP.

## Urutan troubleshooting

- Power: Pastikan aktuator dan elektronik komunikasinya mendapat suplai sebelum memeriksa yang lain.
- Wiring: Telusuri pasangan kabel RS-485 dari gateway ke perangkat yang diam: terminal, polaritas, dan kontinuitas.
- Address: Setiap MOV di jalur butuh address unik yang sesuai dengan konfigurasi gateway.
- Polling: Periksa apakah gateway benar-benar mem-polling perangkat dengan register, function code, baud rate, dan parity yang tepat.
- Command & feedback: Kirim perintah dari SCADA lalu baca kembali feedback MOV di SCADA untuk menutup loop.

## Siapa yang cocok ikut

Engineer dan teknisi yang merawat MOV, jalur RS-485, gateway, atau SCADA di terminal dan pabrik, serta supervisor yang perlu tahu asal alarm "tidak terbaca".

Pembawa materi: Rofiqi Hidayat, Control System Engineer, PT Citia Engineering Indonesia.

## Pertanyaan yang sering muncul

Q: Kapan webinar troubleshooting MOV SCADA berlangsung?

A: Jumat, 21 November 2026 pukul 14.00 WIB, online via Microsoft Teams, sekitar 20 menit.

Q: Apakah Citia Micro-Webinar #03 gratis, dan bagaimana cara daftar?

A: Ya, gratis. Balas HADIR ke siTia di WhatsApp +62 813-2206-507, atau pakai tombol pengingat email di halaman ini.

Q: Kenapa sebagian MOV terbaca di SCADA dan sebagian tidak?

A: Karena gangguannya berada di antara gateway dan perangkat yang diam, bukan di SCADA secara keseluruhan. Sesi ini memeriksa power, wiring, address, polling, serta command dan feedback untuk menemukan titik putusnya.

Q: Jalur komunikasi apa yang dibahas?

A: MOV ke RS-485 ke gateway ke SCADA. Pada proyek MOV Citia di Jambi, jalur yang sama ditambah surge protection device di sisi RS-485 dan LAN arrester di antara gateway dan SCADA.

Q: Apakah akan ada rekaman?

A: Citia belum mengumumkannya. Setelah sesi, halaman ini akan menyebut apakah materi atau rekaman tersedia.
