7 / 70 page F-12 F-13 Construction of systems in multi-vendor environments simplified with Serial Gateway Function. 55 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. 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. 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. ● 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 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.

Programmable Terminal Programmable Terminal Enhanced Protocol Macro Functionality Supports No-protocol Communications (Serial Communications Units/Boards with Ver. 1.2 or later) (CPU Unit Ver. 3.0 or later) (Serial Communications Units/Boards with Ver. 1.2 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 (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. Serial Gateway 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). Gateway FINS network Serial communications Component/PLC Truly Seamless Incorporation of OMRON Components and Other Devices into Networks 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. Sent as a CompoWay/ F command Serial Gateway: FINS command "capsule" opened and contents retrieved. FINS command received Temperature Controller Smart Sensor OMRON Components ● Serial Gateway System (Reference) ● CompoWay/F (See note 2.) ● Host Link FINS (Possible only with Serial Communications Units or Serial Communications Boards) Serial Communications Unit Serial Communications Board Data output to printer ● 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.
