This method treats the nodes on your Data Highway Plus link as users
connected to the 1779-KP5.
The LINK number is the LINK number of the Data Highway II link that
the remote Data Highway Plus link is connected to.
The NODE number is the NODE address of the 1779-KP5 that connects
the Data Highway Plus link to Data Highway II.
The USER number is the address of the node on the Data Highway Plus.
For example, the following message instruction is an example of
communicating from a PLC-5 to a PLC-5 on a remote Data Highway Plus
across a bridge. This message instruction reads 1,000 words from a
PLC-5, Node 013 on a remote Data Highway Plus link. It reads these
words from Memory Location N100:0 of the remote PLC-5 and stores
them in Memory Location N100:0 in the initiating PLC-5.
