Example 1 In this example, data cannot be transferred between Controller Link Units due
to some cause such as a routing table error.
Example 2 In this example, data cannot be transferred between a Controller Link Unit and
a CPU Unit.
Example 3 In this example, the specified destination node or the next relay node does not
exist.
If an error occurs, check the MRES and SRES codes for the node in question,
and correct the problem.
6-7-3 Response Codes and Troubleshooting
The table below lists response codes (main and sub-codes) returned after
execution of the FINS commands, the probable cause of errors, and recom-
mended remedies.
Upon receipt of some commands, the destination node will issue a request to
another node; the other node is referred to as the third node.
