areas.
• Class1 communication status 'Data link status' (Un\G6030 to Un\G6031)
• Class1 communication status 'Error status' (Un\G6034 to Un\G6035)
• Connection behavior error status 'Class1 connection 1 to 32 error code' (Un\G6262 to Un\G6293)
Status of each connection
'The connection status can be checked by checking the bit corresponding to each connection in 'Data link status' (Un\G6030
to Un\G6031), and 'Error status' (Un\G6034 to Un\G6035).

PING test

A PING test is used to check that an EtherNet/IP device exists on the same EtherNet/IP network.
The FX5-ENET/IP sends a packet to the EtherNet/IP device to check its existence (an echo request). Then, the FX5-ENET/IP
checks whether communication is possible by seeing whether a response (an echo response) is returned.
(1) Echo request
(2) Echo response
Check method
The following methods are available for checking the PING test.
■Checking from EtherNet/IP Configuration Tool for FX5-ENET/IP
Use EtherNet/IP Configuration Tool for FX5-ENET/IP to execute a PING test.
