Ethernet basic services
HTTP (RFC 1945)
HTTP (HyperText Transfer Protocol) is used to transmit Web pages between a
server and a browser. HTTP has been used on the Web since 1990. Web servers
embedded in Schneider Electric automation products provide easy access to
information and diagnostics from anywhere in the network.
BOOTP/DHCP (RFC1531)
BOOTP/DHCP is used to provide devices with IP parameters automatically. This
avoids having to manage each device address individually by transferring this
management to a dedicated IP address server.
The DHCP protocol (Dynamic Host Conguration Protocol) is used to assign
conguration parameters to devices automatically. DHCP is an extension of BOOTP.
Schneider Electric devices can be:
b BOOTP clients, allowing the IP address to be retrieved automatically from a
server, or
b BOOTP servers, allowing the device to distribute IP addresses to the network
stations.
FTP (File Transfer Protocol) & TFTP (Trivial File Transfer Protocol) (RFCs 959, 2228, and
2640)
File Transfer Protocols such as FTP and TFTP provide the basic elements for le
sharing. In an automation device, FTP or TFTP are often used to deliver rmware
updates.
NTP (Network Time Protocol) (RFC 1305)
NTP (Network Time Protocol) is used to synchronize the time of a client device from
a time server.
SMTP (Simple Mail Transfer Protocol) (RFC 0821)
SMTP (Simple Mail Transfer Protocol) is an e-mail transmission service. It is used to
send e-mail between a sender and a recipient via an SMTP email server.
SNMP (Simple Network Management Protocol) (RFCs 1155, 1156, and 1157)
Simple Network Management Protocol (SNMP) is an Internet protocol used to
manage IP based network devices. SNMP is used to:
Monitor network components, such as computer workstations, routers, switches,
bridges, and end devices to view their status.
Obtain statistics about the network, such as bandwidth utilization and detected
errors on the network.
Change information in the device SNMP database, such as when to report a high
temperature condition.
SNMP is comprised of a network manager (usually running on a computer) and
agents (running on the network devices). Network Management Systems (NMS) are
software applications used to manage SNMP managed devices.
QoS (Quality of Service) (RFC 2474)
QoS provides the ability to mark, or “tag”, packets of a specic type or origin so that
in a congested network, the switches will give higher priority to the most important
packets.
RSTP (Rapid Spanning Tree Protocol)
RSTP has been implemented in Schneider Electric automation products to allow
multi-port devices to be connected in ring congurations. It helps prevent the
formation of broadcast storms and monitors the state of the ring.
Should a link in the ring become disconnected, the protocol routes packets in a
different direction to help ensure continuity of service.
Schneider Electric offers a Network Management software application tailored for
the industrial control environment. ConneXium Network Manager has been
developed with Automation and Controls professionals in mind. ConneXium
Network Manager provides a window in network equipment operation to help
improve plant productivity. The software can be used to:
b Discover network devices and generate a network map
b Set network performance thresholds and alerts for detected errors to help avoid
downtime
b Manage ports (multiple ports at once)
b Baseline network performance
b Document the network
b Generate a report to send to technical support
b Interface to SCADA via the built-in OPC server
The software is compatible with third-party as well as Schneider Electric network
devices.
