 General Requirements for Using the FA-M3 Controller
 Avoid installing the FA-M3 controller in the following locations:
- Where the instrument will be exposed to direct sunlight, or where the operating
temperature exceeds the range 0°C to 55°C.
- Where the relative humidity is outside the range 10 to 90%, or where sudden
temperature changes may occur and cause condensation.
- Where corrosive or flammable gases are present.
- Where the instrument will be exposed to direct mechanical vibration or shock.
- Where the instrument may be exposed to extreme levels of radioactivity.
 Use the correct types of wire for external wiring:
- Use copper wire with temperature ratings greater than 75°C.
 Securely tighten screws:
- Securely tighten module mounting screws and terminal screws to avoid problems
such as faulty operation.
- Tighten terminal block screws with the correct tightening torque as given in this
manual.
 Securely lock connecting cables:
- Securely lock the connectors of cables, and check them thoroughly before turning on
the power.
 Interlock with emergency-stop circuitry using external relays:
- Equipment incorporating the FA-M3 controller must be furnished with emergency-
stop circuitry that uses external relays. This circuitry should be set up to interlock
correctly with controller status (stop/run).
 Low impedance grounding:
- For safety reasons, connect the [FG] grounding terminal to a Japanese Industrial
Standards (JIS) Class D Ground*1 (Japanese Industrial Standards (JIS) Class 3
Ground). For compliance to CE Marking, use braided or other wires that can ensure
low impedance even at high frequencies for grounding.
*1 Japanese Industrial Standard (JIS) Class D Ground means grounding resistance of 100Ωmax.
 Configure and route cables with noise control considerations:
- Perform installation and wiring that segregates system parts that may likely become
noise sources and system parts that are susceptible to noise. Segregation can be
achieved by measures such as segregating by distance, installing a filter or
segregating the grounding system.
 Configure for CE Marking Conformance:
- For compliance to CE Marking, perform installation and cable routing according to the
description on compliance to CE Marking in the “Hardware Manual” (IM34M6C11-
01E).
 Keep spare parts on hand:
- Stock up on maintenance parts including spare modules, in advance.

vi
IM34M6H41-02E 2nd Edition : Aug. 1, 2005-00
 Discharge static electricity before operating the system:
- Because static charge can accumulate in dry conditions, first touch grounded metal to
discharge any static electricity before touching the system.
 Never use solvents such as paint thinner for cleaning:
- Gently clean the surfaces of the FA-M3 controller with a cloth that has been soaked
in water or a neutral detergent and wringed.
- Do not use volatile solvents such as benzine or paint thinner or chemicals for
cleaning, as they may cause deformity, discoloration, or malfunctioning.
 Avoid storing the FA-M3 controller in places with high temperature or
humidity:
- Since the CPU module has a built-in battery, avoid storage in places with high
temperature or humidity.
- Since the service life of the battery is drastically reduced by exposure to high
temperatures, take special care (storage temperature should be from –20°C to
75°C).
- There is a built-in lithium battery in a CPU module and temperature control module
which serves as backup power supply for programs, device information and
configuration information. The service life of this battery is more than 10 years in
standby mode at room temperature. Take note that the service life of the battery may
be shortened when installed or stored at locations of extreme low or high
temperatures. Therefore, we recommend that modules with built-in batteries be
stored at room temperature.
 Always turn off the power before installing or removing modules:
- Failing to turn off the power supply when installing or removing modules, may result
in damage.
 Do not touch components in the module:
- In some modules you can remove the right-side cover and install ROM packs or
change switch settings. While doing this, do not touch any components on the
printed-circuit board, otherwise components may be damaged and modules may fail
to work.
 Do not wire unused terminals:
- Do not wire unused terminals of external connection terminal blocks or unused pins
of connectors of the module. Doing so may affect the function of the module.

A1. Overview
The Personal Computer Link Module uses serial communication (RS-232-C,
RS-422/485) to exchange data with higher-level equipment (displays, personal
computers, DCS, etc.).
Installing this module in the FA-M3 and connecting it to a higher-level equipment such
as a display or a personal computer enables you to monitor the operating statuses of the
FA-M3 and FA-M3 devices, as well as perform setup from the higher-level equipment.
Moreover, by attaching a commercially-available external modem (analog modem and
terminal adapter, mobile phone adapter, etc.), you can monitor the devices of the FA-M3
from a remote personal computer.

A1-2
IM 34M6H41-02E 2nd Edition : Aug. 1, 2005-00
A1.1 What is Personal Computer Link Module?
The Personal Computer Link module:
- Connects to higher-level equipment such as displays and personal computers and
performs serial communication.
- Enables reading of values from and writing of values to the FA-M3 devices (relays
and registers), as well as uploading and downloading of programs.
- Eliminates the need to create programs on the FA-M3 for communication.
- Enables remote access of the FA-M3 when connected to an external modem, TA
(terminal adapter), mobile phone, etc.
- Enables transmission of messages to a beeper, etc.*
* Message transmission to beepers is not available in some countries and regions.

A1.2 What can the Module Do?
nPersonal Computer Link Function
The Personal Computer Link module is used to connect to high-level equipment such as
displays, personal computers, DUONUS*1, DCS*2, etc. When a FA-M3 PC link
command is transmitted from the high-level equipment, the Personal Computer Link
module returns a reply (response).
*1: Compact Field Server from Yokogawa Electric Corporation. It enables real-time monitoring of field data of the FA-M3
from a WWW browser or in an Internet environment, using the Webmetry field monitoring package.
*2 : Distributed Control System from Yokogawa Electric Corporation.
Command
"What's the
value of
D00001?"
Response
"It's $12EF."
FA10201.VSD
Higher-level
equipment
FA-M3
By exchanging commands and responses, all devices (D registers, I relays, current
values of timers/counters, etc.) of the FA-M3 CPU module can be read and written.
Moreover, personal computer link also enables uploading and downloading of ladder
programs, reading and setting of date and time, reading of error logs and alarms,
reading of user logs, etc. (For details, refer to the list of commands).
This communications is transparent to user programs on the FA-M3. (That is, no
communications program is required on the FA-M3).
CAUTION
PC link commands are issued according to the timing of the high-level equipment. To
transmit data to the high-level equipment according to the timing of the FA-M3, you can
either poll for data continuously from the high-level equipment, or alternatively, you can
write a program that uses the “Event Transmission Function” described later in this
subsection to transmit an event to the high-level equipment from the FA-M3, and have
the high-level equipment read the data once it receives this event.

A1-4
IM 34M6H41-02E 2nd Edition : Aug. 1, 2005-00
nEvent Transmission Function
You can send any data that is 30 words*1 or shorter from the FA-M3 to a higher-level
equipment. Event transmission requires some programming on the FA-M3 side. (You
can send an event by simply storing the data to be transmitted into the register of the
Personal Computer Link module and then turning on the Request to Send relay).
To send numeric data as ASCII character strings, simply turn on a 1-bit relay and the
module will automatically performs ASCII conversion and transmission.
Although PC link commands are processed according to the timing of the higher-level
equipment, the event transmission function allows data to be transmitted according to
the timing of the FA-M3.
CAUTION
Up to 30 words*1 (60 bytes) of data can be transmitted at each event transmission. To
transmit more than 30 words of data, write programs that use the event transmission
function to notify the higher-level equipment of a request to get data and when the high-
level equipment receives the event, it uses PC link commands to read data longer than
30 words.
*1 : On the F3LC12-1F, the limit is extended to 127 words.
nModem Connection Function
By attaching a commercially-available external modem, you can do auto-dialing, re-
dialing, send messages to beepers, etc. and use a password function to ensure security
on receiving, etc.
Besides modems using normal analog lines, you can also connect to the FA-M3 using
digital lines by connecting to a TA (terminal adapter) or even access the FA-M3 from a
place without telephone lines by connecting to a mobile phone adapter.
