PING Test
The PING test checks existence of an Ethernet device on the same Ethernet network.
This test is performed on the network of stations connected to the engineering tool by sending packets for check. If a
response returns, the communication can be performed.
"Ethernet Diagnostics" window [PING Test] button
■Procedure
Set the required items in "Input Item" and click the [Execute] button to execute the PING test. The test results are displayed in
the "Result" box.
• When executing the PING test from the RJ71EN71 and the RnENCPU (network part) by connecting the
engineering tool and CPU module with a USB cable, network number and station number setting is required
to specify the PING executing station.
• When the Ethernet diagnostics are started with a setting other than "No Specification" in "Other Station
Setting" on the "Specify Connection Destination Connection" window, the PING test cannot be used.
■Action for abnormal end
If the test fails, check the following and perform the test again.
• Whether the Ethernet-equipped module is properly mounted on the base unit
• Connection to the Ethernet network
• Parameter settings written in the CPU module
• Operating status of the CPU module (whether or not an error has occurred)
• IP addresses set in the engineering tool and the PING test target station
• Whether the external device has been reset after the Ethernet-equipped module was replaced
