Parameters
Destination IP Address (Command)
The IP address (in hexadecimal) of the destination node for the PING command echo request packet.
Timeout Value (Command)
The wait time for the echo reply packet. The value is set in seconds. The timeout time is set at 20 seconds if the
value is specified as 0. If the echo reply packet is not received within the set time limit, the code for a timeout
error will be set as the results storage response code.
Remarks
PING Command
The PING command runs the echoback test using the ICMP protocol. When the PING command is executed,
an echo request packet is sent to the remote node ICMP. Correct communications are confirmed when the
returned response packet is received normally. The echo reply packet is automatically returned by the remote
node ICMP.
Response Codes
FINS/TCP CONNECTION REMOTE NODE CHANGE REQUEST
Requests a remote node change for the FINS/TCP connection.
The default destination IP address in a connection in which the EtherNet/IP Unit or built-in EtherNet/IP port is
used as a client is the destination IP address set under the FINS/TCP Tab Page in the Unit Setup. By sending
this command to the EtherNet/IP Unit or built-in EtherNet/IP port, the destination IP address for the specified
connection can be changed to another IP address.
Remote node changes can be made only for connection numbers specified as FINS/TCP clients in the Unit
Setup.
