Using a Data Highway Plus Link Number
When you use a Data Highway Plus link number, you can address up to
64 nodes to your Data Highway Plus link.
To use a Data Highway Plus link number to address a Data Highway Plus
node, you must:
Not enable the route update messages. This means that your 1779-KP5
can receive route updates, but it cannot send a route update to inform
other 1779-KP5 modules on where to find the Data Highway Plus link.
Use station-management commands to send the routes from an
intelligent device on your network to the other 1779-KP5 modules.
When your device sends the FIXED ROUTE to all local 1779-KP5
modules, these modules will update the route for all other links on the
network. For more information, refer to your 1779-KFL, -KFLR or
1779-KFM, -KFMR documentation.
Important: The address of the initiating Data Highway Plus node must
be between 02 and 20 (octal) so that the reply message can be returned.
Figure 5.5 shows an example configuration using a remote Data Highway
Plus link.
