The Modbus protocol provides an industry standard method that Modbus devices use for parsing messages. This protocol was developed by Modicon, Incorporated, for industrial automation systems and Modicon programmable controllers.
Here is the presentation on ' MODBUS COMMUNICATION PROTOCOL'.
Industrial Ethernet, Part 1: TechnologiesControlEng
Industrial Ethernet implementations continue to gain traction on the plant floor and in process plants. What are the key industrial Ethernet technologies being installed today and why? Learn from automation system integrators about criteria used to choose types of switches, cabling, and topologies being applied for industrial Ethernet applications. Ethernet survey results are discussed. An exam and certificate are available for one professional development hour (PDH), according to Registered Continuing Education Program (RCEP) rules from the American Council of Engineering Companies.

Introduction to Modbus to Ethernet Device Servers and Modbus TCP to RTU GatewaysICP DAS USA, Inc.
The ICP DAS USA tGW-700 series are Modbus TCP to RTU/ASCII Device Servers that enable a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through Ethernet networks. They eliminates the cable length limitation of legacy serial communication devices. The tGW-7000 serial device servers can be used to create a pair-connection application (as well as a serial-bridge or serial-tunnel application), and can then route data over TCP/IP between two serial Modbus RTU/ASCII devices; which is useful when connecting to mainframe computers, servers or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability.

The TDS-700 series are Serial-to-Ethernet Device Servers that add Ethernet and Internet connectivity to any RS-232 and RS-422/485 device. Virtual COM ports are set up with he VxComm Driver/Utility so the built-in COM port of the TDS-700 series can be virtualized to a standard PC COM port in Windows. The TDS-700 device servers can be used to create a pair-connection application (as well as a serial-bridge or serial-tunnel), and then route data over TCP/IP between two serial devices. It's useful when connecting to mainframe computers, servers or other serial devices that do not themselves have Ethernet capability.

A computer network, or simply a network, is a collection of computer and other hardware components interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network. Simply, more than one computer interconnected through a communication medium for information interchange is called a computer network.

MQTT (Message Queuing Telemetry Transport),它是為IBM和Eurotech共同
製定出來的protocol,在MQTT的官網可以看到它對MQTT的介紹:
MQTT is a machine-to-machine (M2M)/”Internet of Things” connectivity
protocol. It was designed as an extremely lightweight publish/subscribe
messaging transport.
所以它是為了IOT而設計的protocol,它是基於TCP/IP的協定,並且透過
publish/subscribe的方式做資料傳送與接收。
它的架構如下圖:
