1-1 Overview

1-1-1 Communications

The Host Link System is an optimum and economical communications method

for any size of FA system. The Host Link System can incorporate one or more

host computers interconnected to one or more PCs.

A Host Link System allows a host computer to monitor the operating status and

data areas of the PCs and to control PC operation through transfers of data and

programs.

Host computer

Commands

Responses

CV-series PC

As shown in the figure above, data transfer between the host computer and the

Host Link System is normally initiated when a host computer sends a command

to a PC in the Host Link System. The PC processes each command sent by the

host computer and transmits the results to the host computer.

The user can control the PCs in the Host Link System and monitor operation with

one or more host computers. For example, on a production site, a single host

computer makes it possible to monitor and control the operation of the PCs by

transferring data and programs required for production.

Transmissions from PCs The CV500-LK201 Host Link Unit also allows a CV-series PC to send a com-

mand to a host computer, thus enabling the PC to inform the host computer of

any abnormality arising on the production line that the PC is controlling. The PC

can also communicate with the host computer to check the operating conditions

of the host computer.

1-1-2 Features

CV-series PCs feature a built-in host interface. With this interface, it is possible

to create a Host Link System consisting of CV-series PCs without using any op-

tional Units. When a single interface is not sufficient, however, the

CV500-LK201 Host Link Unit can be mounted to a PC Rack to connect to more

than one host computer. The system created by connecting one or more PCs to

one or more host computers via either the host interface on the CPU or a Host

Link Unit mounted to a PC Rack is called a Host Link System. The main advan-

tages of the Host Link System are described below.

Communications Use either RS-232C or RS-422 communications.

Multiple PCs Connections Up to 32 PCs can be connected to a host computer via RS-422 communications.

Host Monitoring and Control The operating status of the PCs and its memory contents can be monitored and

controlled from the host computer.

New Command System A new command mode called FINS, or CV mode, is provided in addition to the

conventional command mode used by the C-series PCs. Refer to the FINS

Command Reference Manual.

Overview Section 1-1

Double-check System All communications are subject to a parity check and frame check sequence

(FCS) to help eliminate almost all transmission data errors.

Two Communications Ports The Host Link Unit incorporates two communications ports: a 25-pin RS-232C

port and a 9-pin RS-232C or RS-422 (selectable) port. It is possible to use these

two ports simultaneously, thus allowing the Host Link Unit to connect to two host

computers.

Although the host interface on the CPU allows a host computer to send com-

mands to PCs and the PCs to respond to the commands, the PC cannot send

commands to the host computer. The Host Link Unit, however, makes it possible

for the PCs to send commands to the host computer, thus enabling commands

generated by executing SEND(192), RECV(193), and CMND(194) instructions.

The Host Link Unit also enables any node on the network to send commands to

the host computer, even across multiple network levels.

Note The communications delay varies with the baud rate, the amount of data, and

the PC’s execution method (i.e., synchronous or asynchronous). For example, if

the PC uses synchronous execution, the PC’s cycle time will increase transmis-

sion delays. If high-speed processing is required from the host, these factors

must be considered.

Note When the model is changed so that the above commands are no longer sup-

ported, change the user program to perform the same operation using other C-

mode commands or FINS commands.

Communications Port Signals Different communications signals are used for Host Link communications for the

C Series and CVM1/CV Series depending on the model and the type of port. Dif-

ferences in the signals are listed below by port.

ST1, ST2, RT Used. Not used.

If the SR1, SR2, and RT signals are not used, the same communications cable

can be used even if the model is changed. If the SR1, SR2, and RT signals are

used, synchronized transfer of data will not be possible if the model is changed.

Change the system to sync on the CD (carrier detected) signal. Part of the cable

wiring must also be changed.

1-1-5 New/Improved Commands for the CPU Host Interface

New C-mode commands have been added for the CPU Host Interface and the

functionality of existing commands has been improved as follows:

New Commands

• RL/WL: Read and write commands for the CIO Area.

• RH/WH: Read and write commands for the CIO Area.

• CR: Read command for the DM Area.

• R#/R$/R%: SV read commands.

• W#/W$/W%: SV change commands.

• *: Initialization command.

Improved Commands

• The Link Area (CIO 1000 to CIO 1063) and Holding Area (CIO 1200 to

CIO 1299) can now be specified for the KS, KR, KC, and QQ commands.

• CVM1-CPU21-EV2 can now be read for the MM command.

The above new and improved commands can also be used with all V1 CPUs

with lot numbers in which the rightmost digit is 5 (jjj5) or higher.

Note The above new and improved commands cannot be used with the

CV500-LK201 Host Link Unit.

1-2 System Configuration

A Host Link System can be connected using RS-232C and/or RS-422 lines.

1-2-1 RS-232C

If a RS-232C line is used to connect a Host Link System, only one PC can be

connected to the host computer.

Transmission Distance The maximum transmission distance varies with the method in which a host

computer and PC are connected. There are three connection methods avail-

able: via wire cable, via Optical Fiber Cable and an Optical Interface, and via

optical fiber cable and Link Adapters.

CV-series PC

RS-232C

Host computer (mainframe, personal

computer, or mini-computer)

RS-232C Cable The maximum transmission distance is 15 m if a host computer and PC are con-

nected via RS-232C cable.

Optical Interface The maximum transmission distance is 500 m if a host computer and PC are

connected via two Z3RN-A-5 Optical Interfaces and a Z3F2-4DjM Optical Fi-

ber Cable. The following accessories are necessary. Here, RS-232C cable con-

nects the PC to one Optical Interface and the host computer to the other Optical

Interface, and the Optical Fiber Cable connects the two Optical Fiber Interfaces.

The AC Adapters provide power to the Optical Interfaces.

Note The cable connecting the Optical Interface and the connector on the PC (for con-

version between 25 pins and 9 pins) is not available from OMRON.

Link Adapters The host computer and PC can be connected via an optical fiber cable and two

3G2A9-AL004-E (or 3G2A9-AL004-PE) Link Adapters. Here, RS-232C cable

connects the PC to one Link Adapter and the host computer to the other Link

Adapter, and the optical fiber cable connects the two Link Adapters. The maxi-

mum transmission distance varies with the kind of optical fiber cable as follows:

Cable 3G2A9-AL004-PE 3G2A9-AL004-E

APF 20 m Connection impossible

PCF 200 m 800 m

APF: all-plastic fiber; PCF: plastic-clad fiber

The Host Link System makes it possible for a PC to connect not only to a host

computer but also a Programmable Terminal (PT). The PT connected to the PC

displays information on the system controlled by the PC as well as errors that

may occur in the system.

Note The CPU Unit will change to MONITOR mode if a PT is connected via a Host Link

connection when the CPU Unit is operating in RUN mode. Use an NT Link con-

nection when connecting in RUN mode. (The mode will not change if the con-

nection is made through an NT Link connection.)
