Because the communication route for data sending is different
from that for data receiving, an error occurs.
*1 An IP communication test related error (error code: 4A28H) occurs in the IP communication test.

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.
The IP communication test cannot be executed if the engineering tool is connected to the RJ71EN71 or the
RnENCPU (network part). Use one of the following methods to check whether no error occurs in the
communication path.
• Directly connect using the Ethernet and execute a PING test in the Ethernet diagnostics. ( MELSEC iQ-
R Ethernet User's Manual (Application))
• Execute a PING from the Ethernet device connected.
