Host computer Communicating
using an OMRON
protocol
Host Link
Host computer (Host computer:PC
= 1:1 or 1:N)
C-mode commands
or FINS commands

frame for a host
computer protocol Protocol macro
Standard system
protocol
Use a standard
system protocol.
User-created
protocol
Use the CX-Protocol to
change a standard
system protocol.
•
General-
purpose
external device
Protocol (including
no-protocol) used
mainly for stop-start
synchronous data
sending and reception Use the CX-Protocol to
create a new protocol.
•
Programming
Device (but not a
Programming
Console)
Remote
programming and
monitoring via a
modem
Note When a Programming Device is connected
to the PC, the Peripheral Bus can be used
by connecting to the ports on the CPU Unit.
This is faster than using Host Link commu-
nications.
•
OMRON
Programmable
Terminal (PT)
High-speed
communications
for multiple PTs
(up to eight).
1:N NT Link
Low-speed
communications
and only one PT
