Compact Solution for Reliable Network Management!
Korenix is pleased to release the brand new performance-optimized JetBox 5300-w Industrial embedded computer Linux with -40 to 80? wide operating temperature for front-end industrial control deployments. The RISC-based computer with low power consumption brings flexibility and reliability to the industrial networking market through its rich interface, featuring 2 LAN ports, 2 USB ports, 2 RS232/422/485 and 2 RS232 serial ports. In addition, the compact JetBox 5300-w carries 4 DI & 4 DO channels allowing users to integrate alarms, indicators, and sensors into their complex networking system.
Main features of JetBox 5300-w are:
RISC CPU low power consumption
-40~80? operating temp, fan-less design
Linux programming
Linux customized configuration auto-run via SD card
4-port serial: TCP server mode
Digital I/O controller: 4 DI & 4 DO, DIO scheduling
SNMP control
Modbus gateway (optional)
The JetBox 5300-w supports the Korenix Auto-Run customization setting on SD card, POE Switch which allows users to configure their own Linux commands once the system is booted. By storing the customized data onto the SD card, software engineers can automatically run specific configurations or run specific applications in the JetBox 5300-w embedded computer making the industrial network management easier and more flexible.
Besides, users can benefit from the optional Modbus Gateway function for Modbus applications by enabling serial Modbus RTU devices to communicate with Modbus TCP devices.
In addition to its advanced software features, the fan-less JetBox 5300-w with redundant dual power inputs and -40 to 80? wide operating temperature range provides reliable and secure data management in harsh environmental conditions, becoming the perfect solution for open-pit mines, railcars, railways, public utilities etc

Korenix USA supplies the extra edge for Industrial Networking!
Watch the video related to modbus
This is a VERY impromptu RS-485 Modbus network formed by five process controllers acting as Modbus slaves and a personal computer acting as the Modbus master. Configuration software is used to access parameters in the networked controllers using Modbus data packets to shuttle information back and forth between the controllers and the master computer.
Help answer the question about modbus
How can i connect Twido(Master) and Zelio(Slave) through Modbus?I want to know the memory word location for transmitting on Zelio.
also. i want an Example for twido application on how to read and write from Zelio. it will be very good if the steps comes with explanation. thanks

This is a great project. Will you be so kind to share the project files with me. I want to do some home automation, and this would be ideal.
Thanks for posting your video. It is really good to see pic micro projects.
I am new to pic micro’s and already admire their power.
Thanks
Ivan
Man great work,its relly admirable,I was wondering if i can get this project to have an idea on how to work with citect scada,iam a beginner i hope ill get better like you sumday
,Best of luck for the future,You have a fan of your work.
Modbus is a popular (and cheap/easy) protocol that all Schneider/Modicon PLCs speak. It is cheap because it is in the public domain and everyone has written drivers using that. Twidosoft and Twidosute (free downloads) botj contain Modbus drivers that can be configured, verified, and run with the Modicon PLCs.
Slavery is outlawed in most countries. You'd better watch what you say.
The hardware and wires are the same, Ethernet commonly uses Cat 5E wire and RJ-45 8 conductor connectors. They are the ones that look like an overgrown modular phone plug.
Modbus is a communications protocol, and would not be the same protocol as what your home or office network is using to communicate between computers and printers even though it is Ethernet hardware and wiring.
Modbus would commonly be used between a PLC and other devices such as an engine, turbine or generator controller (Many such devices exist) to gather data and take it back to a central HMI (Human-Machine Interface) or alarm annunciator. Some such devices can be controlled using Modbus as well.
Modbus is the protocol developed by Modicon to talk with a
RTU (Remote Terminal Unit)
Your question does not make sense…….
a "Modbus Splitter" allows two or more Modbus Masters to communicate with a network of one or more Modbus Slaves: Thus "Splitting" the network and allowing multiple Masters to communicate with a single network of Modbus Slaves.
Modbus allows for communication between many devices connected to the same network, Not just computers, but different devices
Take a look at the wiki for exaples and more detailed info
http://en.wikipedia.org/wiki/Modbus
An interface establishes a connection or boundary between the software and hardware. Say, if you want to access information about RAM an interface would provide the programming required to get the information displayed.
Protocol provides a method to acquire the communication. When talking RS232/Rs485 you are identifying converters which manipulate modulation.
For the quality of connectivity over distances you are indeed on the right track. RS232 coupled with Modbus will give you an overall better quality because the transmittion is sent over as plain form (text). Modbus is peer-to-peer but can perform over point-to-point and multidrop networks.
never heard of such a thing
