Connection With Lan Line; Connections That Are Not Direct Connections; Settings Incompatible With Direct Connection; Functions Incompatible With Direct Connection - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

When connecting directly with the CPU module (built-in Ethernet port part), setting is also possible by clicking
the [CPU Module Direct Coupled Setting] button of the "Specify Connection Destination Connection" window.
Precautions

■Connection with LAN line

Do not connect with a LAN line and set direct connection. Data will be sent to all external devices on the LAN line, so this
setting will cause the line load to increase and will affect communication with other external devices.

■Connections that are not direct connections

• Do not use a configuration in which the Ethernet-equipped module and external device are connected with a hub. A direct
connection is not established when the devices are connected with a hub.
• When creating a network connection on the personal computer side, communication with a direct connection is not possible
if two or more Ethernet ports are set to "Enable". Review the personal computer settings so that only the Ethernet port for
the direct connection is set to "Enable", and the other Ethernet ports are set to "Disable".

■Settings incompatible with direct connection

When using the RJ71EN71 or the RnENCPU (network part), a direct connection cannot be established if the following setting
is made in the "Specify Connection Destination Connection" window of the engineering tool.
• When "Other Station (Co-existence Network)" is selected for "Other Station Setting"
• When "Other Station (Single Network)" is selected for "Other Station Setting", and "Other station in the same loop or access
to multilevel system" is selected in the "Network Communication Route Detailed Setting of Ethernet" window

■Functions incompatible with direct connection

The following functions cannot be used when the RJ71EN71 or the RnENCPU (network part) is directly connected. To use the
following functions, connect the CPU module (built-in Ethernet port part) directly or connect the CPU module with a USB
cable.
• CC-Link IE Field Diagnostics
• CC-Link IE Control Diagnostics
