1. Introduction to Ethernet
Ethernet was originally developed by Xerox and then further developed by DEC and Intel.
This networking technology uses Carrier Sense Multiple Access with Collision Detection
(CDSM/CD) protocol and provides transmission speeds up to 100Mbps.
Ethernet is a not a network but more of a standard. It is the most current communication
standard Local Area Network(LAN). This standard defines the type of cable that is used and
the method of Signal Processing.
2. Functional Description of the Ethernet module
The L-WEB module supports the Modbus-TCP protocol. When connected to the Acuvim L
series meter, it is a slave device that can only respond to queries. The default value for the
Modbus Port is 502, however the user defined range is 2000~5999.
This module supports the SMTP protocol, which allows the user to send emails based on
a specific time interval or when a triggered event occurs. It can send mail from encrypted
servers and servers that use different SMTP ports.
The L-WEB module supports the HTTPS protocol, it is used as an HTTPS server where the
default value of the protocol port is 443. Using the HTTPS protocol, the L-WEB can send post
requests to both HTTP and HTTPS servers.
The following are all the protocols supported by the L-WEB module:
• Modbus TCP
• SNMP
• DNP 3.0
• SMTP, SNTP
• HTTP/HTTPs
• FTP
