IP communication test
This function checks whether no error occurs in the communication path within CC-Link IE Field Network when the IP packet
transfer function is used. The following can be checked using the IP communication test:
• Cables are properly connected on the communication path.
• Parameters related to the IP packet transfer function, such as an IP address and routing parameters, are correctly set on
the communication path.
• All the CPU modules and master/local modules on the communication path support the IP packet transfer function.
The following system configuration is used to explain the procedure of the IP communication test.
The IP communication test allows the communication paths in the dotted line above to be checked.

Because the communication route for data sending is different
from that for data receiving, an error occurs.
