In this example, we send a message from the PLC-5 with Data Highway
Plus address 011 (octal), through the 1785-KE at address 021 (octal), to the
master (1771-KGM/PLC-2) at multidrop address 014 (octal).
In this case, the PLC-5 sends the command to:
local destination: address 021
remote destination: address 014
The command remains in the 1785-KE (address 021) buffer until the
master polls address 011. The 1785-KE recognizes address 011 as a PLC-5
on its Data Highway Plus link and sends the command to the master. When
the master finishes processing the reply, it sends it to the PLC-5 through
the 1785-KE. The 1785-KE is transparent to the master.
The following examples show the T50 message instructions necessary to
send PLC-2 Unprotected Read and Unprotected Write commands from the
PLC-5 (address 011 octal) to the master (address 014 octal) through the
1785-KE.

This example writes eight words from integer file 7, word locations 0
through 7, to the PLC-2/1771-KGM master node (014 octal), data table
words 050 through 057 (octal).
Program a message (MSG) instruction with the parameters shown below.
Also, you must set up the message instruction for continuous mode by
toggling N30:0/11 to ON.
