Addressing from Data Highway II
Chapter 4
4Ć6
Important: If you use a file value of greater than 15, the value wraps
around to zero. For example, a value of 16 specifies File 0, a value of 17
specifies File 1, etc.
You must enter the PLC-5 address in the following address format:
$ E [Major Section] . [File #] . [Element] . [Sub-Element]
If you send a full PLC-3 six-level address to a PLC-5, the PLC-5 will
return an error.
Addressing Data Highway Plus from a 1779ĆKFL or 1779ĆKFM Device
To address a Data Highway Plus node from a programmable device
connected to a 1779-KFL, -KFLR or 1779-KFM, -KFMR, the device
must enter the appropriate LINK, NODE, and USER values in the
message packet.
The LINK value is always 00 for local addressing.
The NODE value is the node address of the 1779-KP5 that connects you
to the destination Data Highway Plus link (the link that contains the node
you want to communicate with).
The USER value is the Data Highway Plus address of the node you want
to communicate with.
For example, if you send a message to:
a PLC-5 at Address 13 (octal)
on a Data Highway Plus connected to a 1779-KP5 with the Data
Highway II Node Address 16 (octal)
your message packet looks similar to this:
NODE
16
LINK
00
EXT SEL USER
