Ip Communication Test - Mitsubishi Electric MELSEC Q Series Reference Manual

4.3.3

IP communication test

When the IP packet transfer function is used, whether no error occurs in the communication route within CC-Link IE
Field Network is checked. The following can be checked using the IP communication test:
• Cables are properly connected on the communication route.
• Parameters related to the IP packet transfer function, such as an IP address and routing parameters, are
correctly set on the communication route.
• If a CPU module or a CC-Link IE Controller Network module that does not support the IP packet transfer
function is connected in the communication route.
The following system configuration is used to explain the procedure of the IP communication test.
