 Input Port
This port is used to input EtherCAT communications data. Always connect it to the output port on
another device. Normal communications will not be possible if you connect to the input port on
another device.
 EtherCAT Slaves
Each EtherCAT slave outputs the output data that it received from the EtherCAT master through the
EtherCAT network. It also sends input data to the EtherCAT master through the EtherCAT network.
• Each slave has one input port and at least one output port.
• In the EtherCAT network, you can use the salves and Junction Slaves that are listed below in total
up to the maximum number of slaves.
• Assign node addresses to the slaves and Junction Slaves. The node address can be any value
within the settable node address range, and can be assigned without any distinction between the
slaves and Junction Slaves. But any node address should not be used more than once.
• The EtherCAT slaves can be classified into two: whether they support synchronization based on
a distributed clock (DC) or not.
a) Non-synced Slaves
These slaves perform sequence control that does not require synchronization between them.
Digital I/O Slaves and Analog I/O Slaves are among this type. They do not support a distrib-
uted clock (DC).
b) Synced Slaves
These slaves are synchronized based on the distributed clock (DC). Servo Drives and
encoder input slaves are among this type.
Note 1 Refer to 1-3-1 Performance Specifications for details on the maximum number of slaves
and the settable node address range.
2 The slaves are synchronized even when multiple non-synced slaves and Junction Slaves
are connected.
The following tables lists some of the OMRON EtherCAT slaves that are available.
