Term Explanation and Definition

PDO Communications

(Communications using

Process Data Objects)

This method is used for cyclic data exchange between the

master unit and the slave units.

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

allocated in advance is refreshed periodically each EtherCAT

process data communications cycle (i.e., the period of primary

periodic task).

The NJ-series MachineAutomation 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 MachineAutomation

Controller in the following ways.

・With device variables for EtherCAT slave I/O

・

WithAxis Variables for Servo Drive and encoder input slave to

which assigned as an axis

SDO Communications

(Communications using

Service Data Objects)

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

data from the master unit when required.

The NJ-series Machine Automation Controller uses SDO

Communications for commands to read and write data, such as

for parameter transfers, at specified times.

The NJ-series MachineAutomation 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.
