Set the nodes and networks from which FINS write operations will be enabled. The total number of nodes set to be
excluded from write protection will be automatically set.
A maximum of 32 nodes can be set. If these settings are not made (i.e., if the total number of nodes is 0), write operations
will be disabled for all nodes but the local node.
Note: This setting is valid only when FINS write protection has been enabled.
