2. Terms and Definitions

Term Explanation and Definition

Slave Slaves are devices connected to EtherCAT. There are various types of

slaves such as servo drivers handling position data and I/O terminals

handling the bit signals.

Object Represents information such as in-slave data and parameters.

PDO

communications

(Communications

using Process Data

Objects)

One type of EtherCAT communications in which process data objects

(PDOs) are used to exchange information cyclically and in realtime.

This is also called “process data communications”.

PDO Mapping The association of objects used for PDO communications.

PDO Entry PDO entries are the pointers to individual objects used for PDO

mapping.

ESI file

(EtherCAT Slave

Information file)

An ESI file contains information unique to the EtherCAT slaves in XML

format.

You can load ESI files into the Power PMAC IDE, to easily allocate

slave process data and make other settings.

ENI file

(EtherCAT Network

Information file)

An ENI file contains the network configuration information related to

EtherCAT slaves.

Power PMAC IDE This computer software is used to configure the Controller, create user

programs, and monitor the programs.

PMAC is an acronym for Programmable Multi-Axis Controller.

3. Precautions

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

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

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

Precautions and Precautions for Safe Use in the manuals for each device that is 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, reproduce, or distribute a part or the whole of this document

without the permission of OMRON Corporation.

(5) The information contained in this document is current as of April 2019.

It is subject to change without prior notice for improvement purposes.

The following notations are used in this document.

Indicates a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury, or may result in serious

injury or death.Additionally, there may be severe property

damage.

Indicates a potentially hazardous situation which, if not avoided,

may result in minor or moderate injury, or property damage.

Precautions for Correct Use

Precautions on what to do and what not to do to ensure correct operation and performance.

Additional Information

Additional information to read as required.
