10.1 Checking with LEDs
Action
• Check whether the buffer memory values are normal.
• Take the action corresponding to the value of 'Class1 connection 1 to 32
error code' (Un\G6262 to Un\G6325). (Page 149 Connection behavior
error status (Un\G6262 to Un\G6293))
• Check that 'EtherNet/IP communication start request' (Un\G37.b0) is on.
• If 'EtherNet/IP data link continuation specification' (Un\G5004) is set to "16:
continue EtherNet/IP communication" , turn 'EtherNet/IP communication
start request' (Un\G37.b0) on again.
Action
• Check whether the operating status of the EtherNet/IP device is normal.
(Page 121 EtherNet/IP communications cannot be performed)
• Check for errors in the line status.
• The line may be busy, so retry at a later time.
Action
Take the actions displayed in the module diagnostics. (Page 109 Module
diagnostics)
• Connect the Ethernet cable again.
• Perform a PING test to check the line status. (Page 118 PING test)
Revise the following items with EtherNet/IP Configuration Tool for FX5-ENET/
IP.
• Model and name of the connected EtherNet/IP device
• IP address of the connected EtherNet/IP device
• Version of the registered EDS file
• 'Check that 'EtherNet/IP communication start request' (Un\G37.b0) is on.
• Check and correct the data communication program.
