Cara Mudah Mengkonfigurasi Inverter

Labels: , , , , , ,

Tahukah anda, apa itu inverter?

Inverter merupakan alat/komponen untuk mengatur kecepatan motor-motor listrik/servo. Atau bisa disebut converter, drive. Cuma kalau untuk servo lebih dikenal dengan istilah servo drive. Dengan menggunakan inverter motor listrik menjadi variable speed. Kecepatannya bisa diubah-ubah atau disetting sesuai dengan kebutuhan.

Didunia otomatisasi industri, inverter sangat banyak digunakan. Aplikasi ini biasanya terpasang untuk proses linear (parameter yang bisa diubah-ubah). Linear ya seperti grafik sinus. atau untuk sistem axis (servo) yang membutuhkan putaran/aplikasi yang presisi.

Mungkin kita kenal dari semua vendor automasi industri pasti membuat inverter juga. Contohnya saja Allen Bradley, Siemens, Hitachi, Panasonic, Omron, Mitsubishi, Danfoss dan masih banyak lagi merek-merek lain. Dari masing-masing brand tersebut mempunyai kelebihan dan kekurangan masing-masing.

Anda pasti tahu didalam inveterter kita harus mensetting parameter yang disesuaikan dengan komponen yang akan di kontrol via inveter tersebut. Contohnya: Tegangan Motor Listrik, Ampere, Frekwensi, High Speed, Torsi, dll. Dengan cara yang manual menggunakan display hal tersebut bisa dilakukan dengan mengikuti manual book yang dikeluarkan oleh vendor inveter tersebut.

Protokol komunikasi yang diimplementasikan oleh setiap inveter berbeda-beda. Ada yang menggunakan Analog output PLC, Profibus, Device NET, Sysmac (Omron), USS, Controlnet dll.

Nah disini, saya memperkenalkan software MCT-10 (VLT Motion Control Tool) yang dikeluarkan oleh DANFOSS. Dengan menggunakan software ini dan kabel serial (COM1) yang dihubungkan antara PC dan Inventer, process configurasi menjadi sangat mudah. Kita hanya menggunakan sebuah kabel interface DB9/RS232 dari PC ke inverter. Selain mudah dalam penggunaannya, dalam operation dilapangan jika mempunyai jenis inveter yang sama dengan aplikasi beban yang sama, kita bisa langsung mendownload file configurasi ini dari satu inverter ke inverter yang lainnya. Lebih mudah kan?.... mijit-mijit tombol inverterpun sudah tidak perlu lagi.

Ingin tahu lebih banyak mengenai software ini, silahkan Klik Disini untuk DOWNLOAD! Jika anda ingin mendowload softwarenya silahkan Cek Disini! Gratiss ko...

Dibawah ini contoh display dari software MCT-10 tersebut.




Jika anda menggunakan inveter Omron, mungkin anda tahu sofware CX-Drive.

Kita bahas di lain waktu... Bersambung...



PLC Timeline

Sejarah PLC? Bisa dilihat disini.

This timeline of the development of the PLC by different manufacturers is a work in progress. If you have something to contribute or correct especially concerning Siemens or Mitsubishi then please contact me.

PLCdev's article on The Birth of the PLC gives more information on how programmable logic controllers first got started.

What is SCADA ?

Labels: , , , , , , , , , , ,

1. Introduction

On 20 Sept. 2000, the Finance Committee approved the proposal to negotiate a contract with ETM A.G. (Eisenstadt, Austria) for the supply of PVSS - ETM's SCADA - for developing the control systems of ALICE, ATLAS, CMS and LHCb. In addition the SCADA Working Group, that was set up by the CERN Controls Board, recommends PVSS as one of the SCADA products for the development of future control systems at CERN.

These decisions are the accomplishment of around thirteen person-years (FTE) of effort - spanning over more than three years - to identify and evaluate a proper industrial control system that copes with the extreme requirements of high energy particle physics experiments such as those of the LHC.

Widely used in industry for Supervisory Control and Data Acquisition of industrial processes, SCADA systems are now also penetrating the experimental physics laboratories for the controls of ancillary systems such as cooling, ventilation, power distribution, etc. More recently they were also applied for the controls of smaller size particle detectors such as the L3 muon detector and the NA48 experiment, to name just two examples at CERN.

SCADA systems have made substantial progress over the recent years in terms of functionality, scalability, performance and openness such that they are an alternative to in house development even for very demanding and complex control systems as those of physics experiments.

2. What does SCADA MEAN?

SCADA stands for Supervisory Control And Data Acquisition. As the name indicates, it is not a full control system, but rather focuses on the supervisory level. As such, it is a purely software package that is positioned on top of hardware to which it is interfaced, in general via Programmable Logic Controllers (PLCs), or other commercial hardware modules.

SCADA systems are used not only in industrial processes: e.g. steel making, power generation (conventional and nuclear) and distribution, chemistry, but also in some experimental facilities such as nuclear fusion. The size of such plants range from a few 1000 to several 10 thousands input/output (I/O) channels. However, SCADA systems evolve rapidly and are now penetrating the market of plants with a number of I/O channels of several 100 K: we know of two cases of near to 1 M I/O channels currently under development.

SCADA systems used to run on DOS, VMS and UNIX; in recent years all SCADA vendors have moved to NT and some also to Linux.
