Ethernet Controllers
Ethernet Remote Monitoring and Control
Ethernet remote monitoring support a graphic user interface, based on a WEB server and at least on M2M protocol. This determines the two main alternatives for their usage – stand-alone or as a part of SCADA system. The graphic user interface (GUI) helps the stand-alone usage. No need for special software to work with the devices. All settings and subsequent remote monitoring and control are carried out in a standard browser – Chrome, Firefox, IE, Opera, etc.
Ethernet is the most widely installed local area network (LAN) technology. Ethernet is a link layer protocol in the TCP/IP stack, describing how networked devices can format data for transmission to other network devices on the same network segment, and how to put that data out on the network connection.
Ethernet is a network protocol that controls
how data is transmitted over a LAN. Technically it is referred to as the
IEEE 802.3 protocol. The protocol has evolved and improved over time
and can now deliver at the speed of a gigabit per second.
An Ethernet controller is a piece of computer hardware that manages and maintains a computer's connection to a wired network. The Ethernet controller thus plays an integral role in Internet usage and other network functions. A software driver controls the on-board functions of the network device.
The devices from TCW1xx series are with an 8-bit chipset and use 10MBit connectivity. They are designed to perform simple tasks. These devices do not support TLS encryption for SMTP, data logger, and graph functionality. However, they support at least one M2M protocol.
With good planning, they can be part of a small to medium sized systems for home and industrial automation. The controllers are suitable for environmental monitoring in data centers and server rooms.
The actively produced devices from TCW2xx series have much more powerful 32-bit chipset and support 10/100MBit connectivity.
All they maintain M2M protocols – MODBUS TCP/IP, SNMP v2, HTTP API with
XML/JSON status files and HTTP Post for client-server systems.
All devices of this series support TLS encryption for SMTP. Some of them support and data logger functionality and the ability to view the recorded data through a standard browser.

A building management system BMS is a computer-based control system installed in buildings that controls and monitors the buildings mechanical and electrical equipment such as ventilation, lighting, power systems, fire systems, and security systems. A BMS consists of software and hardware; the software program, usually configured in a hierarchical manner, can be proprietary, using such protocols as C-Bus, Profibus, and so on.
Vendors are also producing BMS's that integrate using Internet protocols and open standards such as DeviceNet, SOAP, XML, BACnet, LonWorks and Modbus.
