Echelon LNS DDE Server - Manual (Page 40)

To select another folder, either enter it manually or use the Browse button to search
for one. The server validates the path entered when you press the Apply or OK
buttons.
Use the Edit button to start the LNS Resource File Catalog Utility. This utility can
be used to edit the catalog file. Folders containing format and other resource files
may be added or removed from the catalog. You can combine changing the folder
and editing the catalog. If you start the LNS Resource File Catalog Utility and the
selected folder does not contain a catalog, a new and empty catalog is created
automatically.
When changing the folder, or when adding or removing a folder from the catalog, you
must stop and restart the LNS DDE Server for the change to take effect.
See Appendix A for more information on resource files.
Global Database Path Setting
This setting specifies the folder where the LNS Server’s global database is stored.
This database contains information about the names and locations of all the
networks that are managed by the LNS Server. The specified folder must exist and
contain a valid LNS global database. In most cases this setting should never be
changed from the default setting. Entering a folder that does not exist or that
contains a corrupted database will render the LNS Server and LNS DDE Server
inoperable.
Use the Browse button to locate the global database folder. To select another folder,
either enter it manually or use the Browse button to search for one. The server
validates the path entered when you press the Apply or OK buttons.
Remote Settings
Remote Operation
This setting specifies that the LNS Server is running on another PC; in this
situation, the DDE Server runs as a remote client. There are two types of remote
clients, full and lightweight. A full client runs on a PC other than the LNS Server
and is attached to a L ON W ORKS or L ON W ORKS /IP channel (a channel which sends
L ON W ORKS messages within IP packets). A lightweight client runs on a PC other
than the LNS Server and is attached to an LNS/IP channel (a channel which sends
LNS messages bundled within IP packets).
See the LonMaker User's Guide or the LNS for Windows Programmer's Guide for
more information about lightweight and full clients.
In order to run as a remote full or lightweight client, the LNS Server must be
running on a PC that is attached to the same network as the PC running the LNS
DDE Server (but not necessarily the same channel). When remote client operation is
enabled, all requests to look up network, subsystem, device, LONMARK object,
network variable, and configuration property names are forwarded to the PC that
