If the basic settings (in particular the IP address and subnet mask) have been made correctly, then it
should be possible to communicate with nodes on the Ethernet.
The following describes how to use the PING command to perform communications testing between
CP2E N
-type CPU Units.
The PING command sends an echo request packet to a remote node and receives an echo response
packet to confirm that the remote node is communicating correctly. The PING command uses the ICMP
echo request and responses. The echo response packet is automatically returned by the ICMP.
The PING command is normally used to check the connections of remote nodes when configuring a
network. The PLC supports the ICMP echo reply functions.
If the PLC returns a normal response to the PING command, then the remote nodes are physically con-
nected correctly.
The PLC automatically returns the echo response packet in response to an echo request packet sent
by another node (host computer or other Ethernet Unit).
