Rancang Bangun Alat Pemilah Logam Berdasarkan Ukuran Menggunakan Elektropneumatik Berbasis PLC

Tujuan dari penelitian ini adalah membuat sebuah prototipe sistem pemilah barang logam berdasarkan ukuran tinggi dan pendek menggunakan Programmable logic control (PLC). Sensor proximity dengan tipe induktif digunakan untuk mengenali ukuran benda logam. Untuk benda logam dengan ukuran tinggi akan di simpan ke tempat penyimpanan yang ada di bagian ujung convejor sedangkan untuk benda pendek akan di dorong oleh silinder ke tempat penyimpanan yang ada di bagian samping convejor. PLC di program dengan menggunakan Bahasa ladder diagram memalui software GX Works 2. Dari hasil pengujian yang dilakukan, keseluruhan sistem mampu bekerja dengan baik dan mampu mengenali objek dengan tepat. Untuk pengembangan kedepannya prototipe dapat dilengkapi dengan tampilan antar muka agar memudahkan pengguna untuk menghitung jumlah barang yang telah dipisahkan.

Software Design of Veriloghdl Code Generation for Ladder Diagram and Data Acquisition Using LABVIEW

The powerful advantages of programmable logic controller (PLC) dominate the process industries. Scan time of the PLC increases with the number of inputs, rungs added in ladder diagram (LD). Researchers have identified and proved that field programmable gate array (FPGA) is more suitable than PLC for high speed applications. PLC executes the instructions represented through LD. FPGA does not support LD. PLC programmers are not familiar with FPGA programming. This work has developed application software to generate equivalent VerilogHDL code for LD using LabVIEW. Novelty in this work is that each rung is defined using an "assign" statement to ensure concurrent execution of all the rungs. A data acquisition system was created to monitor the digital signals handled by the FPGA. The software was verified with a case study of substances mixing and traffic light control system.

Embedded Device Berbasis PLC pada Miniatur Konveyor untuk Pengoperasian Simulator Rejection System

A PLC-based embedded device on a miniature conveyor machine for operating a rejection system has been designed and constructed. The research objectives, namely (i) design and manufacture of an integrated system, (ii) making program structure based on a ladder diagram, and (iii) measuring the performance of an integrated system. Integrated system assembled from a miniature of the conveyor machines and belt installation, and installing the dc motor, while the rejection system assembly by placing several sensors, installing stepper motor, and wiring to the PLC system. Programming based on ladder diagram carried out by determining algorithms, compiling the ladder diagram, addressing the input/output, and compiling and uploading the program from PC to PLC. The performance of the integrated system was observed when (a) observation during synchronization, (b) observations of sensor readings while the rejection system simulator is operating, and (c) observation and measurement of the processing time of the rejection arm. Overall results have been obtained in the form of a PLC-based embedded device for the rejection system simulator on observations of the condition of the bottle caps for beverage packaging. Based on the overall observation, the PLC-based embedded device has functioned to operate the rejection system can be implemented at a manufacturing scale.

Mengganti Mikrokontroller Mesin Dust Collector pada PT. xxx dengan PLC OMRON CP1E-NA20CD-R

As a result of the production of powder processing causes a lot of dust around the production machine and factory. This of course can cause pollution. Dust needs to be collected using a Dust Collector (DC) machine. The controller on the DC machine at PT. xxx is often damaged in the control unit and requires repairs at a cost of around Rp. 5,000,000 per unit. In facts there are about 10 units of machines at PT.xxx that must work all. Because of DC machines are often damaged in their controllers, the maintenance department made a development to make replacement DC machine controllers. Namely using the Programmable Logic Controller (PLC). This PLC replaces the microcontroller unit on the DC machine, PLC uses ladder diagram programming language that is easily understood by some people working in the world of control. PLC parts that are easily found in the market and programming languages that are easy to understand and reliability make one of the reasons this PLC is used to replace the microcontroller unit.

SISTEM KONTROL KONVEYOR PEMILAH LOGAM MENGGUNAKAN PLC OMRON CP1E

Penelitian yang dilakukan bertujuan untuk membuat sistem kontrol pemilah logam secara otomatis menggunakan PLC Omron CP1E30 dengan program ladder diagram yang dirancang dengan aplikasi CX-Programmer Masukan PLC yang digunakan terdapat satu buah sensor proximity dan dua buah sensor photoelektrik sedangkan keluarannya terdapat dua buah motor penggerak konveyor dan satu buah solenoid. Sensor proximity berfungsi untuk mendeteksi benda logam dan bukan logam dan sensor photoelektrik berfungsi untuk mendeteksi adanya suatu benda yang melaluinya.. Keluaran PLC terdapat dua buah motor konveyor berfungsi membawa benda yang akan dipisahkan dan selenoid yang berfungsi memisahkan benda logam dan bukan logam Berdasarkan hasil pengujian ternyata sistem dapat berfungsi dengan baik dimana pada saat PLC diaktifkan maka motor konveyor 1 akan aktif untuk membawa benda yang akan dipilah, pada saat benda melewati photoelectric sensor 1 maka motor konveyor 1 akan berhenti untuk dideteksi oleh proximity sensor, apabila benda tersebut adalah non logam maka motor konveyor 2 akan membawa benda non logam tersebut sampai di ujung konveyor 2, setelah benda non logam itu di deteksi oleh photoelectric sensor 2, maka motor konveyor 1 aktif kembali untuk mengantarkan benda selanjutnya. apabila proximity sensor mendeteksi benda tersebut adalah logam maka selenoid di aktifkan sehingga memisahkan benda logam tersebut.

Sistem Kendali Pengisian Jus Otomatis Menggunakan Sensor Infrared Dan Waterflow Berbasis PLC

The need for automatic beverage vendors is quite high in public places and crowds, which will be more efficient and efficient than the beverage vendors who are human-friendly. This paper discusses the design of an automatic beverage vendor based on a programmable logic controller (PLC). The PLC used for this study is the production of Outseal, which has an Outseal Studio simulation program with a ladder diagram control. This automatic beverage vendor consists of input, process, and output. The primary input of this system is an infrared sensor, and a flow meter sensor to detect the cup's presence and how much juice poured to the cup. The DC motor and pump are the control output. A simulation program demonstrates the effectiveness of this automatic beverage supplier with the Outseal studio.
