Sistem berjalan pada PLC ABB AC500 dan memantau distribusi listrik di gedung, gardu, power house dan generator di lokasi. | Info | Isi | | --- | --- | | Tahun | 2023 | | Lokasi | Bandung, Jawa Barat | | Status | Selesai | | Jenis pekerjaan | PLC | | Diperbarui | 2026-08-24 | ## Tentang pekerjaan ini ### Sistem yang ada Sistem otomasi distribusi listrik dan SCADA mengawasi jaringan listrik PT Bio Farma (Persero) di Bandung. Beberapa PLC master ABB AC500 (CPU PM573, modul komunikasi CM597) mengumpulkan data dari banyak power meter dan peralatan listrik melalui Ethernet industri, gateway Modbus dan jaringan RS-485. Server SCADA pusat dan operator workstation menampilkan hasilnya. ### Lingkup pekerjaan - **Troubleshooting PLC.** Status CPU dan modul komunikasi, koneksi antara PLC master dan perangkat komunikasi, komunikasi Ethernet dan serial, port, kabel serta antarmuka, dan koneksi laptop engineering langsung untuk diagnostik. - **Diagnostik komunikasi.** Seluruh rantai dari server SCADA melalui Ethernet industri, PLC master dan gateway Modbus hingga power meter. Pemeriksaan mencakup komunikasi terputus, data tidak valid, peralatan lapangan yang tidak terjangkau, dan perbedaan data antara perangkat lapangan dan SCADA. - **Jaringan power meter.** Modbus melalui RS-485 multidrop, dengan meter dari beberapa pabrikan pada setiap master. - **Verifikasi SCADA.** Suplai PLN, generator, switchgear MV, breaker, ATS, LVMDP, transformator dan panel distribusi pada mimic diagram dan single-line diagram. - **Parameter listrik.** Tegangan, arus, daya aktif, reaktif dan semu, faktor daya, frekuensi dan energi. - **Status switching.** Indikasi ON, OFF, TRIP, LOCAL, REMOTE dan MAINTENANCE. - **Monitoring generator.** Status operasi, jam jalan, tegangan, arus, frekuensi, daya, energi dan informasi pemeliharaan, termasuk controller Woodward EasyGen 3000. - **Halaman pemeliharaan.** Peralatan yang telah atau hampir mencapai jadwal pemeliharaan. - **Tinjauan arsitektur.** PLC master terdistribusi dan segmen jaringan yang masuk ke satu SCADA pusat, termasuk managed switch, gateway, serta topologi Ethernet dan Modbus. - **Pelaporan energi.** Tren daya, daya aktif puncak, konsumsi energi dan laporan energi bulanan. ### Cakupan Monitoring mencakup gedung bernomor di seluruh lokasi, power house, dua gardu, area produksi vaksin, fasilitas kontrol kualitas dan hewan uji, pengolahan air, boiler house, utilitas, pengemasan, gudang dan administrasi. Satu master menghubungkan power meter beberapa area produksi dan QC, utilitas serta panel switchgear melalui satu jaringan. ## Kontak - Perusahaan: PT Citia Engineering Indonesia - Email: services@citiaengineering.com - Telepon: +62 21 278 20286 - Kantor: Jl.
