Truly Seamless Incorporation of OMRON Components and Other Devices
into Networks
When the CPU Unit (Ver. 3.0 or later) or
Serial Communications Board or Serial
Communications Unit (Ver. 1.2 or later)
receive a FINS command containing a
CompoWay/F command (see note 1.) via
network or serial communications, the
command is automatically converted to a
protocol suitable for the message and
forwarded using serial communications.

Note 1: FINS
Abbreviation for Factory Interface Network Service. A
command system for message services common to
OMRON networks. FINS commands can be sent across up
to 8 network levels*, including serial communications paths
using a serial gateway. (*Possible only with CS/CJ-series
CPU Unit Ver. 2.0 or later.)
Note 2: CompoWay/F
CompoWay/F is an integrated communications protocol
used for OMRON general-purpose serial communications.
It is used by Temperature Controllers, Digital Panel Meters,
Timer/Counters, Smart Sensors, Cam Positioners, Safety
Controllers, etc. (as of July 2004).
● Serial Gateway System (Reference)
When CompoWay/F commands are enclosed
in FINS commands and sent to Serial
Communications Boards or Serial
Communications Units (Ver. 1.2) or serial
ports on CPU Unit Ver. 3.0, the enclosed
CompoWay/F command is retrieved using a
Serial Gateway Function and sent as a
CompoWay/F command.

More Ports for Even More
Serial Device Connections
Protocol macros make it easy to create serial
communications protocols (communications
frames, error checks, retries, error
processing, etc.) to match those of remote
communications devices. Multiple ports are
provided for this function. Each PLC
supports up to 16 Serial Communications
Units (32 ports total) and one Serial
Communications Board (with 2 ports). This
makes it possible to connect up to 34
devices with serial communications at a
speed of 38.4 Kbps. Message length has
been increased from 256 to 1,000 bytes to
give communications more power than ever
before.
Windows-based Software Simplifies
Serial Device Connections
Protocol macros for Serial Communications
Units and Boards can be created using the
CX-Protocol, thus enabling message tracing
and greatly reducing the time involved in
connecting various serial devices.
Enhanced Protocol Macro
Functionality
(Serial Communications Units/Boards with Ver. 1.2 or later)
● Baud rate increased from 38,400 bps to
57,600 bps for faster communications.
● Standard system protocol added for
greater connectability with components
and PLCs.
• CompoWay/F Master
• Host Link Master functions
• Mitsubishi Computer Link Master
Wide Range of Applicable
Protocols Allows for High
Value-added Programs
The CS1 Series supports a wide range of
serial communications protocols, such as
Host Link, no-protocol, NT Link, peripheral
bus, and more. These allow for high
value-added programs such as MMI,
communications, and data processing.
The Fastest Communications in the
Industry with High-speed NT Links
Combine with one of the NS Series
Programmable Terminals (NS12, NS10, or
NS7) to enable connecting Highspeed NT
Links. Using NT Link terminology together
with a communications speed of 115 Kbps
provides high-speed response.

Supports No-protocol Communications
(Serial Communications Units/Boards with Ver. 1.2 or later)
● No-protocol communications supported for Serial
Communications Units and Serial Communications
Boards.
● This mode enables components to be connected to
multiple communications ports using no-protocol
communications.
● Serial port I/O instructions executable using no-protocol
communications from Serial Communications Units and
Serial Communications Boards (TXDU, RXDU, TXD,
and RXD) are supported for CPU Units with Ver. 3.0 or
later.
