System Configuration For The Initial Setup, Maintenance, And Inspection - Mitsubishi Electric MELSEC iQ-R Series User Manual

System configuration for the initial setup, maintenance, and
inspection
Connect a high speed data communication module to a personal computer on a 1:1 basis by using a direct connection.
Communication can be established without specifying the IP address of a high speed data communication module when using
a direct connection. (Broadcast is used.)

Considerations for using a direct connection
■Connecting to a LAN line
Do not perform communication by connecting to a LAN line directly.
This may increase the line load and affect communications of other devices.
■Connections which are not direct connections
Do not set the direct connection in a configuration where a high speed data communication module is connected to a single
configuration personal computer via a hub.

■Conditions where communication cannot be established by using a direct connection
If either of the following conditions is satisfied, the communication by a direct connection may not be established. In that case,
review the settings of a high speed data communication module and a configuration personal computer.
• When all the bits of the high speed data communication module IP address corresponding to the '0' parts of the
configuration personal computer subnet mask are ON or OFF
Ex.
High speed data communication module IP address: 64.64.255.255
Configuration personal computer IP address: 64.64.1.1
Configuration personal computer subnet mask: 255.255.0.0
• When all the bits of the high speed data communication module IP address corresponding to the host address of each
class for the configuration personal computer IP address are ON or OFF
Ex.
High speed data communication module IP address: 64.64.255.255
Configuration personal computer IP address: 192.168.0.1
Configuration personal computer subnet mask: 255.0.0.0
• The IP addresses for each class are as follows:
Class A: 0.x.x.x to 127.x.x.x, Class B: 128.x.x.x to 191.x.x.x, Class C: 192.x.x.x to 223.x.x.x
• The host addresses for each class are the '0' parts as follows:
Class A: 255.0.0.0, Class B: 255.255.0.0, Class C: 255.255.255.0
