5.3 Checking the Network Status
5.3
Checking the Network Status
Use the following methods to check the EtherNet/IP network status.
• Network diagnostics of EtherNet/IP Configuration Tool
• Checking with the buffer memory
• PING test
Network diagnostics of EtherNet/IP Configuration Tool
The network diagnostics of EtherNet/IP Configuration Tool can be used to check the connection information of EtherNet/IP
devices.
For details on EtherNet/IP Configuration Tool, refer to the following.
Page 49 EtherNet/IP Configuration Tool
Displaying the connection status of EtherNet/IP device
Enabling diagnostic mode in EtherNet/IP Configuration Tool displays the connection status of the EtherNet/IP device.
1.
Connect a personal computer on which EtherNet/IP Configuration Tool is installed to the same network as the
RJ71EIP91.
2.
Start EtherNet/IP Configuration Tool.
3.
Add the EtherNet/IP device to the network configuration settings. ( Page 94 Procedure for Registering EtherNet/IP
Devices)
4.
Switch EtherNet/IP Configuration Tool to the online state.
[File] Ö [Go Online]
5.
Write the set parameters to the RJ71EIP91.
[File] Ö [Download]
6.
Enable diagnostic mode.
[Device] Ö [Diagnostic]
7.
When the diagnostic mode is enabled, the connection status of EtherNet/IP devices is displayed in the network
configuration setting.
To check the connection status of EtherNet/IP devices, the actual network configuration needs to be written to the RJ71EIP91
with EtherNet/IP Configuration Tool. When the diagnostic mode is enabled, the network configuration setting cannot be
changed.
To start EtherNet/IP communications, 'EtherNet/IP communication start request' (Y10) must be turned off and
on and 'EtherNet/IP communication in process' (X10) must be in the ON state.
(1) An EtherNet/IP device is connected, and EtherNet/IP communications are in progress.
(2) An EtherNet/IP device is connected, but EtherNet/IP communications are not in progress.
