Equipment Characteristics in Ethernet Network
1 EQUIPMENT CHARACTERISTICS IN ETHERNET NETWORK
Below are listed the main features for Ethernet communication module for SCA06 servo drive.
There are 3 different acessories, according to the specified communication protocol:
–ECO5: EtherNet/IP protocol.
–ECO6: Modbus TCP protocol.
–ECO7: 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
SCA06 ladder programming.
1.2 ETHERNET/IP SPECIFIC CHARACTERISTICS
It is supplied with an EDS file for the network master configuration.
Allows up to 16 input words and 16 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 16 input words and 16 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.

Interfaces Description
3 INTERFACES DESCRIPTION
The SCA06 servo drive uses an accessory to provide a Ethernet interface for communication.
3.1 ETHERNET ACCESSORY
Supplied items:
–Installation guide.
–Ethernet accessory.
XNOTE!
There are 3 different accessories, according to the specified communication protocol:
ECO5: EtherNet/IP protocol.
ECO6: Modbus TCP protocol.
ECO7: PROFINET IO protocol.
It is important to use the accessory model according to the desired protocol for application.
3.2 CONNECTORS
The accessory for Ethernet communication has two RJ45 connectors for network connection. The connector pin
out follows the Fast Ethernet 100BASE-TX standard, using two pairs of cables for data transmission and reception.
The housings of the Ethernet connectors, which are normally connected to the cable shield, have connections be-
tween themselves and to the protective earth via an RC circuit.
3.3 INDICATION LEDS
The Ethernet accessory has an LED indicator on the Ethernet port, and two bi-color status LEDs. These LEDs have
the following functions and indications:
