(c) When networks are connected in a loop configuration
Be sure to configure the settings correctly so that requests and responses will
take the same route.
A response from the request target is passed back to the station that relayed the
request.
Therefore, if a different route is set, data cannot be transferred and an error will
occur.
(d) On a relay station in the multiple CPU system, when different control CPUs are
set for the network modules
Set the same routing parameters to each of the control CPUs.
