EtherCAT Communication Specification

2．Terms and Definitions

2. Terms and Definitions

The terms and definitions used in this guide are given below.

Term Explanation and Definition

PDO communications

(Process Data Objects

communications)

PDO communications is used for constant data exchange

between a master and slaves. PDO data (i.e., I/O data that is

mapped to PDOs) that is allocated in advance is input and

output each EtherCAT process data communications cycle (i.e.,

the task period of primary periodic task). The NJ/NX-series

Machine Automation Controllers use PDO communications for

commands to refresh I/O data in a fixed control period, including

I/O data for slave units and the position control data for

servomotors. It is accessed from NJ/NX-series Machine

Automation Controllers in the following ways.

・With device variables for EtherCAT slave I/O

・With axis variables for a servo drive and encoder input slaves

to which an axis is assigned

SDO communications

(Service Data Objects

communications)

SDO communications is used to read and write specified slave

data from a master when required. The NJ/NX-series Machine

Automation Controllers use SDO communications for

commands to read and write data, such as for parameter

transfers, at specified times. The NJ/NX-series Machine

Automation Controllers can read/write the specified slave data,

such as parameters and error information, with the

EC_CoESDORead (Read CoE SDO) instruction or the

EC_CoESDOWrite (Write CoE SDO) instruction.

slave unit A generic name for a device that performs EtherCAT

communications with an EtherCAT master. There are various

types of slave units such as servo drives that handle position

data and I/O terminals that handle bit signals.

node address An address to identify a slave unit connected to EtherCAT.

ESI file

(EtherCAT slave information

file)

It contains information unique to EtherCAT slave units in XML

format. The ESI file can be loaded into Sysmac Studio, to

allocate EtherCAT slave process data and make other settings.

3．Precautions

3. Precautions

(1) Understand the specifications of devices which are used in the system.Allow some

margin for ratings and performance. Provide safety measures, such as installing a safety

circuit, in order to ensure safety and minimize the risk of abnormal occurrence.

(2) To ensure system safety, make sure you always read and follow the information provided

in all Safety Precautions and Precautions for Safe Use in the manuals for each device

used in the system.

(3) The user is encouraged to confirm the standards and regulations that the system must

conform to.

(4) It is prohibited to copy, to reproduce, and to distribute a part or the whole of this guide

without the permission of OMRON Corporation.
