Precautions
Precautions for direct connection are shown below.
■Connection to LAN line
When the Motion CPU is connected to LAN line, do not perform communication using direct connection. If performed, the
communication may put a load to LAN line and adversely affect communications of other devices.
■Connection not connected directly
• The system configuration that connects a Motion CPU with an external device using a hub as shown below is not regarded
as direct connection.
• When two or more Ethernet ports are enables in the network connections setting on the personal computer, communication
by direct connection is not possible. In the setting, leave only one Ethernet port enabled for direct connection and disable
the other Ethernet ports.
■Condition in which direct connection communication may not be available
Under the following conditions, direct connection communication may not be available. In that case, check the setting of the
Motion CPU and/or personal computer.
• In the Motion CPU IP address, bits corresponding to "0" in the personal computer subnet mask are all ON or all OFF.
Motion CPU IP address: 64.64.255.255
Personal computer IP address: 64.64.1.1
Personal computer subnet mask: 255.255.0.0
• In the Motion CPU IP address, bits corresponding to the host address for each class in the personal computer IP address
are all ON or all OFF.
Motion CPU IP address: 64.64.255.255
Personal computer IP address: 192.168.0.1
Personal computer subnet mask: 255.0.0.0
