Addressing from Data Highway II
Chapter 4
4Ć8
When you send a message from a node on your Data Highway II link to a
node on a remote Data Highway II link, you address the node using the
LINK, NODE, and USER fields.
Use the LINK field to specify what link the remote node is on. The
LINK value of a remote link can be between 1 and 15. You set the link
value of a remote link using switches on the remote link’s 1779-KP5
(Chapter 3).
Use the NODE and USER fields the same way as normal Data
Highway II addressing. The NODE field specifies the node address on
the remote link. The USER field specifies the user on the remote node.
For example, if you want to send a message to:
User 1
on a 1779-KFL with Node Address 17
on Remote Link 13
your address fields would like like this:
USER
01
NODE
17
LINK
13
You use remote addressing to communicate with a node on a remote Data
Highway Plus link. A remote Data Highway Plus link has a link value
greater than zero.
Important: Only Series B Data Highway II modules support
communication to a remote Data Highway Plus link. The PLC-2 Family
Interface (1779-KP2, -KP2R) and the PLC-3 Family Interface (1779-KP3,
-KP3R) do not offer a Series B version.
Figure 4.3 shows an example of a configuration which uses remote
addressing.
