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.

NOTE!

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.

NOTE!

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.

SRW01-ETH | 10

Network Installation

Figure 4.1: Star topology

It is also possible to make the connection in daisy chain, allowing a topology equivalent to a bus.

Figure 4.2: Daisy chain topology

NOTE!

When the equipment is turned off, the built-in switch is also deactivated, preventing communication

with the subsequent equipment.

4.5 RECOMMENDATIONS FOR GROUNDING CONNECTION AND CABLE ROUTING

The correct connection with the ground decreases problems caused by interference in an industrial environment. The

following are some recommendations about grounding and cable routing:

Always use shielded twisted pair Ethernet cables and connectors with metallic housing.

Connect the equipment grounding via grounding terminal. Avoid the cable connection on multiple grounding

points, especially where there are grounds with different potentials.

Pass signal cables and communication cables in dedicated pathways. Prevent laying these cables next to power

cables.

P0029 – VALUE OF ADDRESSING SWITCHES

Range: 0 to 255 Default: -

Properties: RO

Description:

It presents the addressing switch value identiﬁed at the power-up of the smart relay.

The two addressing switches, close to the SRW01-ETH Ethernet connectors, allow to program the expected IP

address or Station Name.

In order to obtain information about the possible conﬁgurations with switches, refer to item 4.1.

P0313 – ACTION IN CASE OF COMMUNICATION ERROR (FIELDBUS)

Range: 0 = Only Fault Indication

1 = The motor is turned off

2 = Motor is turned off and commands are reset

3 = It changes to Local

Default: 0

Properties: RW, Sys

Description:

It allows the selection of the action to be executed by the device, if it is controlled via network and a communication

error is detected.

Table 5.1: P0313 options

Option Description

0 = Only Fault Indication Fault indication only with no action taken. The indication of fault will be automatically

removed if the fault condition is cleared and the relay status are not either Trip or Error. If

the relay status is Trip or Error, it is mandatory to perform “error reset” in order to remove

the fault indication.

1 = The motor is turned off It switches the motor off, for the operation modes where this commands exists. It is

necessary to perform the error reset in order to remove the indication.

2 = Motor is turned off and

commands are reset

It switches the motor off and resets the commands. It is necessary to perform the error

reset in order to remove the indication.

3 = It changes to Local It changes to local mode, providing that the local/remote selection is programmed to

be executed via Fieldbus. The indication of fault will be automatically removed if the

fault condition is cleared and the relay status are not either Trip or Error. If the relay

status is Trip or Error, it is mandatory to perform “error reset” in order to remove the fault

indication.

The following events are considered communication errors:

P0800 ... P0819 – READ WORDS #1 ... #20

Range: 0 to 65535 Default: -

Properties: RW, Sys

Description:

These parameters allow programming the number of read words (inputs: slave → master), as well as the content of

each word.

Each of words #1 to #20 can be programmed by the user. By using these parameters it is possible to program

the number of another parameter whose content must be made available at the network master input area. If, for

instance, one wants to read from the SRW01-ETH smart relay the motor current in Amps, one must program the

value 3 in one of these parameters, because the parameter P0003 is the one that contains this information. It is

worthwhile to remind that the value read from any parameter is represented with a 16 bit word. Even if the parameter

has decimal resolution, the value is transmitted without the indication of the decimal places. E.g., if the parameter

P0003 has the value 4.7A, the value supplied via the network will be 47.

It will be added to the input area the words programmed in these parameters if the contents programmed for these

parameters is different from zero. The ﬁrst parameter set to zero disables the use of itself and the other parameters

in the sequence. For example, if you set:

P0800 = 680 (P0680 = status)

P0801 = 3 (P0003 = current)

P0802 = 0 (disabled)

Only two read words (state and current) will be communicated with the master. The same number of words pro-

grammed into the equipment must be programmed in the master when conﬁguring the network.

Modbus TCP protocol allows to access each parameter directly, and do not distinguish cyclic and acyclic data.

NOTE!

For the changes in these parameters be effective, the equipment must be powered off and on again,

or an update must be performed by P0899.

P0850 ... P0869 – WRITE WORDS #1 ... #20

Range: 0 to 65535 Default: -

Properties: RW, Sys

Description:

These parameters allow programming the number of write words (outputs: master → slave), as well as the content

of each word.

The words #1 to #20 can be programmed by the user. By using these parameters it is possible to program the number

of another parameter whose content must be made available at the network master output area. If, for instance, one

wants to write to the SRW01-ETH smart relay the control word, one must program the value 682 in one of these

parameters, because the parameter P0682 is the one to program this information. It is worthwhile to remind that the

value written from any parameter is represented with a 16 bit word. Even if the parameter has decimal resolution, the
