The number of error frames for the input port (PortA) for node address 4 is 123, so you can see
that error frames were received on the input port for node address 4.
Therefore, you can assume that there is a problem between the output port (X3) for node ad-
dress 64 and the input port for node address 4.
This corresponds to location (A) (B) or (C) in the network configuration diagram.
Concretely, you can assume the following possible error locations.
• The device at node address 64
• The cable between the output port at node address 64 and the input port at node address 4
or the connectors at those ports
• The device at node address 4
