Ping Test; Action For Abnormal End - Mitsubishi Electric MELSEC iQ-RJ71EN71 User Manual

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.

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.

• 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
