Serial Gateway 

Truly Seamless Incorporation of OMRON Components and Other Devices into Networks.

(CPU Unit Ver. 3.0 or later)

(Serial Communications Units/Boards with Ver. 1.2 or later)

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 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.

• CompoWay/F (See note 2.)

• Host Link FINS (possible only with Serial Communications Boards or Serial Communications Units Ver.1.2 or later)

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 Unit (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 function

  • 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 (NS8, NS10 or NS12) to enable connecting High-speed NT Links. Using NT Link terminology together with a communications speed of 115 Kbps provides high-speed response.
