Explanation and Definition

PDO

This method is used for cyclic data exchange between the master unit and

Communications

the slave units.

(Communications

PDO data (i.e., I/O data that is mapped to PDOs) that is allocated in

using Process

advance is refreshed periodically each EtherCAT process data

Data Objects)

communications cycle (i.e., the period of primary periodic task).
The NJ-series Machine Automation Controller uses the PDO
Communications for commands to refresh I/O data in a fixed control
period, including I/O data for EtherCAT Slave Units, and the position
control data for the Servomotors.
It is accessed from the NJ-series Machine Automation Controller in the
following ways.
・With device variables for EtherCAT slave I/O
・With Axis Variables for Servo Drive and encoder input slave to which
assigned as an axis

SDO

This method is used to read and write the specified slave unit data from

Communications

the master unit when required.

(Communications

The NJ-series Machine Automation Controller uses SDO Communications

using Service

for commands to read and write data, such as for parameter transfers, at

Data Objects)

specified times.
The NJ-series Machine Automation Controller can read/write the specified
slave data (parameters and error information, etc.) with the
EC_CoESDORead (Read CoE SDO) instruction or the EC_CoESDOWrite
(Write CoE SDO) instruction.

Slave unit

There are various types of slaves such as Servo Drives that handle
position data and I/O terminals that handle the bit signals.
The slave unit receives output data sent from the master, and sends input
data to the master.

Node address

A node address is an address to identify a unit connected to EtherCAT.

ESI file

The ESI files contain information unique to the EtherCAT slaves in XML

(EtherCAT Slave

format.

Information file)

Installing an ESI file enables the Sysmac Studio to allocate slave process
data and make other settings.

UOP

Peripheral I/O (UI/UO) is a group of specialized signals for robot control.

Digital I/O

Digital I/O (DI/DO) is a group of general-purpose digital signals for data
exchange with peripheral equipments.
