A1. Overview

The Model F3LR01-0N Fiber-optic FA-bus Modules (hereinafter referred to as modules) are interface modules to configure the distributed control system through a fiber-optic FA bus. This bus connects F A-M3 main units and sub-units. Using this bus, users can configure an efficient remote I/O system.

If the above modules are installed on the FA-M3 main units and sub-units, and connected with each other with fiber optic cables, modules on the subunits will be handled at the same level as in the main units.

A1.1 Features

Features of remote I/O systems (1) Users do not need to worry about I/O refresh time in ladder programming. (2) Subunits can include contact input/output modules and other special modules such as

RS-232-C communications modules, excepting FA link modules and Ethernet modules.

(3) If subunits are configured with an FA-bus module, users can access those units in the

same way as the modules in the main units are accessed.

configured with the modules are:

A1-1

(4) Because of its optical communications, the system will not be influenced by noise. (5) Maximum extended cable length is 200 meters.

1: I/O implies “Input” and “Output,” — stated as “contact input/output.” Remote I/Os are located far away from the CPU

module, but can be handled in the same way as for contact input/output modules close to a CPU module.

IM 34M6H45-01E 1st Edition : Feb.28,1999-00

A1.2 Application Examples

If a remote I/O system is configured, some problems could occur, which include configuration (environment) setting, uses of specific remote I/O instructions, and I/O refresh time, or the like.

Whereas if a remote I/O system is configured with a fiber-optic FA-bus module, the above problems will not occur. The system configuration example is shown below.

A4.4.3 Notice on Connecting Fiber Optic Connectors

Handle fiber optic cables with great care. When the fiber optic cables are laid, first read Sumitomo Electric Industries Manual and then ask the workers for specific applications as described in the manual.

CAUTION

• DO NOT touch optical connector core wires and protect them from dirt and dust. Otherwise, transmission performance may deteriorate or a communications error could occur.

T o store them, be sure that they are provided with appropriate cable covers.

• Each time the fiber optic cords or cables are connected, keep the cable extension within 0.7% of permissible extension percentage. When the cable is fixed, also keep the cable extension within 0.2% of permissible extension percentage. If the cable extension is beyond these limitations, fiber optic cables or cords may be disconnected. For this purpose, DO NOT cause excess tension, bending, or twisting or the like of the cables or cords.

A4.5 Preliminary Checks

After installing modules and wiring fiber optic cables, check that all electrical connections have been completed and the modules are in communications-enabled states.

Apply power to the units and check the following two points: (1) Check that the RDY (green) lamp lights up.

If this lamp does not light up, the fiber-optic FA-bus module may not be connected to the base module correctly . T urn off the power and attach the module to the base module correctly . Then apply the power and be sure that the RDY lamp lights up.

(2) Check that the ERR lamp remains turned off.

If the lamp lights up, communications will be disabled. If the power of the destination unit is off, turn on its power and check that the ERR lamp is turned off. If it is still on, transmission lines may be faulty . (Fiber optic cables may be disconnected).

A7. RAS Function

A7.1 Function for Detecting an Error Location

A7.1.1 Check the LED Display

When an error occurs in this module or when there is a cable break in the transmission line, the error LED (ERR) or alarm LED (ALM) of the CPU module turns on.

The LED of this CPU module turns on, even when an error occurs in a module other than this module.

To decide whether the cause of the lighted LED lies in this module, check the status of the RDY and ERR LEDs of the Fiber-optic F A-bus module mounted on each unit.

The relation between the fiber optic cable break and the lighting of the LED in the module is as shown below.

A7.2 Output Shutdown Function due to a

Communications Error

A7.2.1 Overview of Output Shutdown Function

This module is equipped with a function which shuts down the output of the I/O module when a communications error occurs.

When an error occurs in the fiber-optic FA-bus module, this function prevents it from af fecting the system or from resulting in hazardous operation or unstable operation of the system.

For example, when the transmission line breaks, it detects the error and immediately turns off the output signals of each I/O module and avoids any risk.

The output shutdown function on a communications error is valid only on configurations having one main CPU (with no add-on CPU).

A7.2.2 Output Shutdown of Subunit

A7-2

Subunit

CAUTION

• When it is necessary to reset the output due to power supply breakdown or transmission line error, use the output module with less than 32 points, turn on the shutdown switch of the F3LR02 and set an Output Reset using the CPU configuration setting. This setting cannot be used in a 64-point output module.

• When it is necessary to hold the output due to power supply breakdown and transmission line error, turn of f the shutdown switch of the F3LR02 and set an Output Hold using the CPU configuration setting.

• The Output Reset function cannot be used in multiple CPU systems (systems loaded with add-on CPU). Always use the Output Hold setting.

The operation of the output module corresponding to various combinations of setting is shown below for your reference.

B1. Overview

The Model F3LR02-0N Fiber-optic FA-bus T ype 2 Modules are interface modules to configure the distributed control system through a type 2 fiber-optic FA bus. This bus connects FA-M3 main units and sub-units. Using this bus, users can configure a remote I/O system efficiently.

If the above modules are installed on the FA-M3 main units and sub-units, and connected with each other with an optical fiber cable, modules in the subunits will be handled at the same level as in the main units.

1: I/O implies “Input” and “Output,” -- stated as “contact input/output.”

This module is mainly used for:

• Distributed installations of I/O modules

• System expansion

B3.5 Precautions

• The F3BU04 and F3BU06 Base Modules with Version R01 or later allow use of different slot numbers during the module installation. For other base modules, use slot numbers starting from slot number 1.

• Only one substation can be installed on the base module.

• For address setting, do not duplicate unit slot addresses in the system.

• Master stations (unit number = 0) cannot be separated on a unit-by-unit basis. Be sure to set slot number 1 for the master station.

• In a star connection, multiple F3LR01 modules may be used; but not in loop and daisychained connections.

• For use with the F3LU01 µ-bus Master Station Module, do not duplicate unit numbers.

(1) Check that the RDY (green) lamp lights up.

(2) Check that ERR1 and ERR2 lamps remain turned off. If these lamps light up, commu-

nications will be disabled. If the power of the destination unit is off, turn on its power and check that the ERR lamps are turned off. If these are still on, transmission lines may be faulty (optical fiber cables may be disconnected).

Consult Section B7.3, “Troubleshooting Flowchart When “EER1” and “EER2” LEDs Are ON,” for solving problems.

If unused ports are turned on, be sure that the functions set switch on the rear of the module are set correctly .

B4-15

(3) Make sure that the transmission configuration (star, daisy-chained and loop connec-

tions) and the setting of the module right side switch coincide.

(4) Be sure that port 2 on an unused port is vacant. For this, check to see that the switch

number 2 (SW2) on the right side of the module is in the off position. Be sure to cover vacant ports with the connector cover.

(5) Do not duplicate the unit and slot numbers. (6) Check that the optical fiber cable length and the optical port set value coincide. If the

cable length is over 200 meters, be sure to use a GI T ype H-PCF cable.

B4.6 Notice on Applying Power

Perform the following steps when applying power to the main- and sub-units: Apply power to both main- and sub-units simultaneously . Or apply power to the subunits

and then to the main unit. Once the power is supplied to the main unit, programs will start independent of supplying power to subunits. If the above power supplying procedures cannot be followed, refer to the following special relays and registers that compose subunits, to configure application's requirements:

• Special Relays for Correct Transmission Lines through Subunits

These special relays are turned on when all transmission lines of the Fiber-optic FA-bus Type 2 Module are normal. If the subunit power remains of f, or if an error occurs in a transmission line due to a disconnection or the like, the special relays will be turned off.

Using these relays, users can confirm whether an entire system power is already supplied or not, or whether the transmission line is normal.

These relays allow initial setting of multifunctioning modules installed on subunits after applying power to the entire system even with power first applied to the main unit and then subunits.

B6. RAS Function

B6.1 Function for Detecting Error Location

B6.1.1 LED Display

When an error occurs in this module or when there is a cable break in the transmission line, the error LED (ERR) or alarm LED (ALM) of the CPU module turns on to indicate the disorder.

The LED of this CPU module turns on, even when error occurs in a module other than this module.

To decide whether the cause of the lighted LED lies in this module, check the status of the RDY and ERR1 and ERR2 LEDs of the optic-fiber F A bus module mounted in each unit.

The relation between the optical fiber cable break and the lighting of the LED in the module is as shown below.

B6.1.2 Logging Transmission Line Error Location

to Error Log

When an error occurs in the transmission line, logging in an error log is possible. Depending on the condition of the error, the errors are indicated as "fiber-optic F A-bus transmission line error location notification message" and classified into the following two types:

(1) Sub-unit transmission line error

This is a state in which reading/writing for all remote I/O is not possible because of an error in the transmission line or switching off of the power supply of the remote I/O (the modules mounted on the subunits).

B6-8

When an error is detected, it is possible to specify in the configuration whether to “stop” the execution of the program (breakdown) is set to “continue.”

(2) Switching sub-unit transmission line

This is a state in which one cable in the transmission line in the loop system is broken and switching from the main loop to the sub-loop has occurred. Reading and writing to the remote I/O can be done normally .

When this error is detected, the execution of the program continues and the ALM LED turns on.

1 : It can be used in the combination of F3SP21, F3SP25, F3SP35 and ladder program M3.

2 : RUN LED of the sequence CPU module becomes off and the ERR LED becomes on.

3 : ALM LED of the sequence CPU module becomes on.
