Addressing from Data Highway II
Chapter 4
4Ć3
The NODE value for each Data Highway Plus node is the same as the
node address of the 1779-KP5 it is connected to (between 01 and
77 octal). Refer to Chapter 3 for information on setting the node address
of a 1779-KP5 using the thumbwheels on the front panel.
For example, if the NODE value of the 1779-KP5 is 50 (octal), the NODE
value of each Data Highway Plus node connected to it is also 50.
The USER value is the Data Highway Plus node address. The USER
value must be between two and 20 (octal).
The 1779-KP5 reserves USER 01 to identify itself to nodes on Data
Highway II. You can still use Data Highway Plus Address 01 (the
1784-T50 default address), but Data Highway II nodes will not be able to
communicate to this Data Highway Plus node.
For example, a Data Highway Plus node, Address 15 (octal), connected to
the 1779-KP5 at:
NODE
50
LINK
00
would have the Data Highway II address:
USER
15
NODE
50
LINK
00
Important: Due to PLC-2 address limitations, the USER value you use
when sending a command from a 1779-KP2 does not equal the Data
Highway Plus address. For more information, refer to the following
section on PLC-2 addressing. If you are using a 1779-KP2 to
communicate to Data Highway Plus, make sure that the 1779-KP5 node
address is not 00 to 07. The 1770-T3 terminal cannot communicate to
these addresses.
The following sections provide guidelines for addressing Data Highway
Plus nodes from Data Highway II using local addressing.
