ETHERNET/IP

Following it shows operating characteristics of the SCA06 servo drive using the accessory for EtherNet/IP commu-
nication.

INDICATION LEDS

The NS LED present on the Ethernet accessory, have the following information for EtherNet/IP protocol:
Off
Green, solid

CYCLIC DATA

Cyclic data is the data normally used for status monitoring and equipment control. For EtherNet/IP protocol, the
interface supports an I/O connection that allows communication up to 16 input words and 16 output words.
It is necessary the configuration to be made both at the slave and master.
8.3

ACYCLIC DATA

In addition to the cyclic data, the interface also provides acyclic data via explicit messaging. Using this type of commu-
nication, you can access any equipment parameter. Access to this type of data is commonly done using instructions
for reading or writing data, which should indicate the class, instance, and attribute to the desired parameter. The
following table describes how to address the parameters for SCA06 servo drive.
The data is transmitted as an integer value, without the indication of the decimal places.
8.4

EDS FILE

Each device on an EtherNet/IP network has an EDS configuration file, which contains information about the device
functions on the network. This file is used by a master or configuration software to program devices present at
EtherNet/IP network.

State
No power or no IP address.
Connection established.
Waiting for connections.
Duplicate IP address, or fatal error (interface must be reinitialized).
One or more I/O connection timed out.
