5.1.2 Connection to an EtherCAT Network
( 1 ) Connection Method
Connectors CN1 and CN2 of the 264IF-01 Module are on the same circuit in EtherCAT. Connect CN1 to the host side
of the network that includes the EtherCAT master device, and connect CN2 to the subordinate side of a network that
does not include the EtherCAT master device. If no slave device is connected at the subordinate side of the network,
leave it open.
( 2 ) About Topology
In EtherCAT networks any kind of connection is possible, with no specification of the mode of connection, but the con-
nections before and after a 264IF-01 Module must be in the line connection mode.
However, when it is used in the open mode, since the 264IF-01 Module has no MAC address, it cannot be connected
directly to a switching HUB. Where a slave node is to be directly connected to a HUB, connect a slave device that has
a MAC address, then connect the 264IF-01 Module after this point.
Make the selection of open mode or direct mode at the EtherCAT master device.
<Open Mode>
This is the mode in which a switching HUB is used in an EtherCAT network. Slave nodes that are connected directly to
a HUB must have an Ethernet MAC address.
<Direct Mode>
This is the mode in which no switching HUB is used.
