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 real time.
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.
