EtherNet/IP

7.3

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 20 input words and 20 output words.

It is necessary the conﬁguration to be made both at the slave and master.

7.4

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 SRW01-ETH smart relay.

The data is transmitted as an integer value, without the indication of the decimal places.

7.5

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.

The EDS ﬁle is available from WEG website (http://www.weg.net). It is important to note if the EDS conﬁguration ﬁle
is compatible with the ﬁrmware version of the SRW01-ETH smart relay.

7.6

MODBUS TCP CONNECTIONS

The device for EtherNet/IP also provides up to 2 Modbus TCP connections. These connections can be used for
parameterization, as well as access to markers and data used for SRW01-ETH ladder programming. The available
Modbus functions and communication data are described in item 6.

7.7

STARTUP GUIDE

Next it describes the main steps for commissioning SRW01-ETH smart relay on Ethernet network using EtherNet/IP
protocol. These steps represent an example of use. Refer to speciﬁc chapters for details on the steps.
