CPU Overview
Outstanding Connectivity and Compatibility
OMRON provides all of the capabilities and capacity you
need for the advanced programming required for human-
machine interfaces, communications, data processing, and
other required applications.
J Protocols for Advanced Programming
Host Links
Host Link (C-mode) commands or FINS commands placed
within host link headers and terminators can be sent to a
host computer to read/write I/O memory, read/control the
operating mode, and perform other operations for the PLC.
Unsolicited messages can also be sent from the PLC to the
host computer by sending FINS commands from the ladder
program using the SEND(090), RECV(098), and
CMND(490) instructions.
High-Speed NT Links
High-speed NT Links that are three times faster than stan-
dard NT Links are possible with NS-series PTs. This speed
is particularly important when connecting to more than
one PT.
Custom Protocols
I/O instructions for communications ports (TXD(236) and
RXD(235)) can be used for simple data transfers (custom
protocols), such as to input data from bar code readers or
output data to a printer. Start/end codes can be specified,
and RS, CS, and other control signals can be handled.
(Custom protocols can be used only for the CPU’s built-in
RS-232C port.)

1:N NT Links
The PLC can be connected to an Operator Interface Termi-
nal via RS-232C or RS422A/485 ports, and I/O memory in
the PLC can be allocated to various Operator Interface
functions, including status control areas, status notifications
areas, touch switches, lamps, memory tables, and other
objects.
General-purpose Protocols Using BASIC
An ASCII Module can be used to create essentially any
protocol for an external device using the BASIC language,
providing the ability to handle applications for which proto-
col macros cannot be created.
