Equipment Characteristics in Ethernet Network
1 EQUIPMENT CHARACTERISTICS IN ETHERNET NETWORK
Below are listed the main features for Ethernet communication for SRW01-ETH smart relay.
There are 3 different products, according to the specified communication protocol:
–SRW01-ETH-EIP: EtherNet/IP protocol.
–SRW01-ETH-MBTCP: Modbus TCP protocol.
–SRW01-ETH-PNIO: PROFINET IO protocol.
The interface follows the Fast Ethernet 100BASE-TX standard.
It allows communication using the 10 or 100 Mbps rates in half or full duplex mode.
It has a built-in, two-port Ethernet switch.
The Ethernet ports work with Auto-MDIX (automatic medium-dependent interface crossover), a technology which
automatically detects the type of cable used and configures the connection accordingly, eliminating the need of
cross-over cables.
The interface also makes available a Web server (HTTP).
1.1 MODBUS TCP SPECIFIC CHARACTERISTICS
Operates as Modbus TCP server.
The server provides up to 4 simultaneous Modbus TCP connections.
Allows data communication for equipment operation and parameterization, as well as markers and data used for
SRW01-ETH ladder programming.
1.2 ETHERNET/IP SPECIFIC CHARACTERISTICS
It is supplied with an EDS file for the network master configuration.
Allows up to 20 input words and 20 output words for cyclic data communication.
Acyclic data available for parameterization.
Device Level Ring (DLR) and linear network topology supported.
It features up to 2 Modbus TCP connections.
1.3 PROFINET IO SPECIFIC CHARACTERISTICS
It is supplied with a XML file for the network master configuration.
Allows up to 20 input words and 20 output words for cyclic data communication.
Acyclic data available for parameterization.
It features up to 2 Modbus TCP connections.

Ethernet Overview
2 ETHERNET OVERVIEW
Following it is presented general information about the Ethernet technology.
2.1 ETHERNET TECHNOLOGY
Ethernet is a technology for interconnecting local area networks (LAN) based on frames forwarding. It defines wiring
and electrical signals for the physical layer, the frame format and protocol for media access control layer (MAC) of the
OSI model.
Ethernet, however, mainly defines the physical medium and the frame format. Based on Ethernet, multiple protocols
and higher-level services were specified and developed in order to perform desired activities over a network, such as
packet routing, connection establishment, sending and receiving files, etc. Several of these protocols have also been
widely disseminated and employed, such as IP, TCP, UDP, FTP, HTTP.
Widely used to interconnect computers in the office environment, the Ethernet technology also started being used in
industrial environments for interconnection of field devices. For industrial environment also emerged different com-
munication protocols based on Ethernet, among which we can mention Modbus TCP, EtherNet/IP, PROFINET.

Interface Description
3 INTERFACE DESCRIPTION
The SRW01-ETH smart relay has two standard Ethernet ports. Information about the connection and installation of
the equipment to the network is presented bellow.
3.1 ETHERNET INTERFACE CHARACTERISTICS
The interface follows the Fast Ethernet 100BASE-TX standard.
It allows communication using the 10 or 100 Mbps rates in half or full duplex mode.
It has a built-in, two-port Ethernet switch.
The Ethernet ports work with Auto-MDIX (automatic medium-dependent interface crossover), a technology which
automatically detects the type of cable used and configures the connection accordingly, eliminating the need of
cross-over cables.
The housings of the Ethernet connectors – which are normally connected to the cable shield – have connections
between themselves and to the protective earth.
XNOTE!
When the equipment is turned off, the built-in switch is also deactivated.
3.2 INDICATION LEDS
The smart relay SRW01-ETH has LEDs in the each Ethernet port connector (PORT1 and PORT2), besides a bicolor
diagnostics LED (NET).
Figure 3.1: Connectors and LEDs
Those LEDs have the following functions and indications:

Network Installation
4 NETWORK INSTALLATION
This chapter presents recommendations related to equipment installation in an Ethernet network.
4.1 IP ADDRESS
Every equipment in an Ethernet network needs an IP address and subnet mask.
The IP addressing is unique in the network, and each equipment must have a different IP. The subnet mask is used
to define which IP address range is valid in the network.
For the smart relay SRW01-ETH, the programming of the IP address is made using parameters and the addressing
switches present in the product. The address configuration options depend on the protocol according to the product
model - Modbus TCP, EtherNet/IP or PROFINET IO. See the chapter about the desired protocol for the description
of these options.
4.2 COMMUNICATION RATE
The Ethernet interfaces of the SRW01-ETH smart relay can communicate using the 10 or 100 Mbps rates in half or
full duplex mode.
The baud rate is programmed at P0753.
XNOTE!
It is important that, for each Ethernet connection made between two points, the baud rate and the
duplex mode are set to the same option. If the option AUTO is used in one of the points, you must
set the other point also to AUTO, or to half duplex mode.
For PROFINET IO interface, the baud rate is locked to 100 Mbps as required by the protocol.
4.3 CABLE
Recommended characteristics for the cable:
Standard Ethernet cable, 100Base-TX (FastEthernet), CAT 5e or higher.
Shielded cable.
Maximum length between devices: 100 m.
For installation, it is recommended the use of shielded Ethernet cables specific for use in industrial environment.
4.4 NETWORK TOPOLOGY
To connect SRW01-ETH smart relay in an Ethernet network, usually the star connection is made using an industrial
switch.
