Response Codes
Section 6-6
transferred from one Communications Unit to another in an interconnected
network. Example 2 shows a similar situation, except that the remote Unit is
something other than a Communications Unit. In Example 3, the relay error
occurs because either the specified remote node or the next relay node does
not exist.
In the three diagrams, the numbers indicate the following:
(1)
The transmitted data fails to be received.
(2)
The relay error and response code are returned to the com-
mand source.
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 remote 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.
