Proses di industri membutuhkan produktivitas yang tinggi dalam setiap aktivitasnya. Salah satu contohnya adalah proses pengambilan barang di tempat penyimpanan. Sistem yang ada sekarang adalah operator mengambil barang dengan mencari secara manual ke tempat penyimpanan. Hal tersebut akan menimbulkan masalah yaitu proses pengambilan barang membutuhkan waktu yang lama atau terjadi kesalahan dalam pengambilan barang. Tujuan dari penelitian ini adalah merancang sistem pick-by-light dengan komunikasi serial RS-485 dan TCP/IP menggunakan protokol Modbus untuk mendukung aktivitas produksi yang efisien. Pick-by-light adalah sistem yang terdiri dari perangkat lampu sebagai tanda barang tersebut harus diambil, tombol sebagai konfirmasi bahwa barang sudah diambil, dan perangkat pemroses untuk memproses data. Hasil dari pengujian menunjukkan bahwa sistem pick-by-light dapat berjalan dengan baik dengan menerapkan komunikasi serial RS-485 dengan protokol Modbus RTU dan komunikasi TCP/IP dengan protokol Modbus TCP. Hasil ini didapat dari pengujian yang telah dilakukan dengan komunikasi yang berbeda, yaitu menggunakan komunikasi serial RS-485 dan TCP/IP. Dengan demikian, sistem ini dapat diterapkan pada industri manufaktur maupun pergudangan dalam meningkatkan produktivitas pengambilan barang.

ABSTRACTThe molasses monitoring system at sugar factory still uses conventional monitoring by measuring directly on the tank. It is very ineffective because when conducting sale and purchase of molaseses must measure to the tank so that the effectiveness of the sale and purchase transactions is very less.The purpose of this research to increase sale and purchase eficiency of molasses at sugar factories in the madiun area. One such device is a wireless system that can transmit data from the tank so there is no need to measure the tank in the field. Many devices are used such as access point, receiver, analog input based LAN communication, PT100 temperature sensor, level sensor, etc.Analog input-based LAN communication is one device that connects between sensors and computers through a LAN network which is then transmitted by access point through wireless signals so that it can be accessed by the receiver remotely without installing cable as far as 300 meters. Data from receiver can be accessed by computer by using visual studio program as SCADA monitoring interface by using TCP / IP modbus protocol. The result of this research can simplify the process of data retrieval from sugar tank in the field.Keywords: SCADA,Modbus TCP/IP,Monitoring System, WirelessABSTRAKSaat ini sistem monitoring gula tetes di pabrik gula masih menggunakan monitoring konvensional dengan mengukur langsung pada tangki tetes. Hal ini sangat tidak efektif karena saat melakukan transaksi jual beli gula tetes harus mengukur terlebih dahulu ke tangki penampungan sehingga efektifitas dari transaksi jual beli sangat kurang.Tujuan penelitian ini adalah peningkatan sistem pada transaksi jual beli gula tetes pada pabrik gula yang ada di area Madiun. Salah satu perangkat tersebut adalah sistem wireless yang dapat mengirimkan data dari tangki sehingga tidak perlu mengukur tangki di lapangan. Hal tersebut saat ini menjadi salah satu fokus penelitian yang terus dikembangkan. Banyak perangkat yang digunakan seperti acces point, receiver, analog input berbasis komunikasi LAN, sensor suhu PT100, sensor level, dll.Analog input berbasis komunikasi LAN merupakan salah satu perangkat yang menghubungkan antara sensor dan komputer melalui jaringan LAN yang kemudian di pancarkan oleh acces point melalui sinyal wireless sehingga dapat diakses oleh receiver dari jarak jauh tanpa memasang kabel sejauh 300 meter. Data dari receiver dapat diakses oleh komputer dengan menggunakan program visual studio sebagai interface SCADA monitoring dengan menggunakan protokol modbus TCP/IP. Hasil dari penelitian ini dapat mempermudah proses pengambilan data dari tangki gula tetes di lapangan.Kata Kunci: SCADA,Modbus TCP/IP, Sistem Monitoring, Wireless, Komunikasi

This diploma thesis is focused on the analysis of the most well-known industrial protocols and acquaintance with the Dobot Magician robotic arm. The main goal of this thesis is to create an industrial loop, which consists of communication – client and server. The individual components of the industrial loop consist of three robotic arms (including peripherals), their control units (in our case Raspberry PI 3B +), switch, and a server. The control units communicate with the server using two selected industrial protocols, namely Modbus TCP and EtherNET/IP. The result of the work is an endless loop, which tries to resemble the real operation of the assembly and disassembly of the box equipped with dierent items.

This diploma project summarizes a theoretical introduction regarding the issue of traffic light control. Further there is industrial communication discussed, where they are the Ethernet / IP protocol and the Modbus TCP protocol described more in detail. The following is the description of the Logix series programmable controllers. Then the diploma follows up with market research in order to find the most suitable development kit which is used as a trial prototype. Then it is concerned with a development kit with a communication module from AND-TECH company. Software was developed on them, more specifically a library for processor ports, memory and the Modbus TCP protocol. After verifying the functionality of the software, the hardware design was started. From the first site it is development kit and module and from the second site there are input and output circuits. There must be the assessment of the results found during the test operation. The end of the document describes incorrect steps that were repaired in hardware.

This thesis deals with description and implementation of AAS module. This thesis describes the selection of individual components of device. This module will be a part of the testbed Barman project. This project is implemented in accordance with Industry 4.0 trends. Device will be work as reader of information and ingredients from NFC tags placed on a glass. With this information, parent cell can make decision which action will be done with glass. In this thesis, software for hardware operation with AAS module will be created and described. This program will further communicate with the parent program controlling the functionality of the cell itself.

This master’s thesis is focused on behaviour of the TCP/IP protocol on free-space optical link which is affected by the effect of atmospheric turbulence. This causes fluctuation of the received optical power and therefor bit error rate changes. In the simulation model short-time bit error rate is calculated from random generated received optical signal and then used in time-domain analysis of the OMNeT++ network simulator. A buffer in transmitter is designed based on simulation results. It pauses the data transmitting in cases of FSO link outage. This method is then implemented into FPGA device.

In control technique there is evident highly expressive trend of shifting from efficient central managing systems towards smaller systems which are distributed on technology and which are connected by communication bus. There is no need to link all signals to central management system, operation is then distributed and realized directly in individual parts of technology. That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..
