JetNet 5010G is a Managed Industrial Ethernet Switch equipped with 7 10/100TX ports and 3 10/100/1000 RJ-45/100-FX/Gigabit SX/LX combo ports. 2 of the gigabit ports are used to form the nonstop Rapid Super Ring; the 3rd gigabit port is used to connect the upper switch, couple ring or public server. The industrial embedded computer gigabit combo port design allows for flexibility to choose copper or fiber media, 100Base-FX or 1000Base-X, multi-mode or Single mode, for different distances and without stocking different switch models.
JetNet 5010G is designed with a rugged surface in aluminum material, solid design, and a wide operating temperature.
The industrial embedded computer software supports full Layer 2 management features, multi-form ring redundancy, network control, monitor, security and notification.
JetNet 5010G also provides built in watchdog timer, and digital input and relay output to avoid undetected damage.
Blown away by the Industrial Managed POE Switch? Korenix also provides a monitoring architecture which is applicable to many different markets, such as POS, banking, telecom, transportation, industrial automation, energy, power, military, and medical fields. Field site devices such as PLCs, sensors, meters, RFID readers…etc. can be connected to the JetBox 8210 through serial ports, USB ports, and DI/DO. The JetBox 8210 performs as an intelligent agent to monitor the status of field devices and transmit messages to back-end technicians through its dual Industrial Ethernet Switch ports or USB wireless dongle while abnormities occur. Further, the JetBox 8210 with Modbus gateway function let industrial automation developers consolidate field devices into SCADA system easily.

Help answer the question about modbus
Modbus and Modbus ID's??Can anyone explain what a modbus or modbus ID is?
From my understanding i see it as a software identity number that allows various bits of hardware to locate and interact with eachother?

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.
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
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.
never heard of such a thing
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…….
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.
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
