Data Highway Plus to an AsynchronousĆDevice Interface (1779ĆKFL, ĆKFLR)
The following is an example of PLC-5 message instruction that writes 100
words of data from the PLC-5, starting at Memory Location N100:0, to
the first port (USER = 01) of the 1779-KFL. The command is a
PLC-2-type command and stores the data at Memory Offset 010 in the
computer.

This section describes communicating to a node on a remote Data
Highway II link. To address a remote Data Highway II link, you must
send the message over a 1779-KP5 bridge. Figure 5.2 shows an example
configuration.
You can send commands to Data Highway II from Data Highway Plus
Addresses 002 through 020 (octal). You may still assign Address 001 (the
default address for the 1784-T50) and Addresses 021 through 077 (octal)
on your Data Highway Plus network, but these nodes are unable to initiate
messages to nodes on your Data Highway II network.
