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 (32°F to 131°F).
- 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).
 Ground for low impedance:
- For safety reasons, connect the [FG] grounding terminal to a Japanese Industrial
Standards (JIS) Class D (earlier called Class 3) Ground*1 . 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 100 Ωmax.
 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).

vi
IM 34M6H46-01E 1st Edition : Nov. 1, 2005-00
 Keep spare parts on hand:
- Stock up on maintenance parts including spare modules, in advance.
 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 use unused terminals:
- Do not connect wires to unused terminals on a terminal block or in a connector.
Doing so may adversely affect the functions of the module.

1. Overview
The Yokogawa High-speed Link System (YHLS) master module F3LH02-0N has two
YHLS master interface ports for connecting slave units to perform remote I/O.
Table 1.1 Applicable Module
Model Code Module Name
F3LH02-0N YHLS Master Module
1.1 What is YHLS?
Yokogawa High-speed Link System (YHLS) is designed for implementing high-speed
remote I/O in an FA-M3 system. A YHLS system consists of an FA-M3 master module
connected to multiple distributed slave units through a communication cable to allow
high-speed control of remote I/O units from a sequence CPU. It has the following merits:
- Reduced wiring through use of distributed I/O units within a system
- Simple mechanism for high-speed exchange of ON/OFF signals and numerical data
with remote devices.
- Flexibility in building customized application systems using devices from different
partner manufacturers.
- Support for user-built devices.
1.2 Features of YHLS
1.2.1 Communications between Sequence CPU Module and
Slave Units
The module relays actuator ON/OFF signals from the sequence CPU module to slave
units, and relays switch ON/OFF signals from slave units to the sequence CPU module
using its input/output memory areas as buffer.

1.2.2 Withdrawal of Slave Unit
YHLS adopts a bus connection so when a slave unit is switched off or otherwise fails to
communicate, the master module can continue communicating with other normal slave
units.
1.2.3 Automatic Slave Unit Participation
When a withdrawn slave unit is switched on and returns to normal condition, it
automatically resumes communications with the master module.

1-2
IM 34M6H46-01E 1st Edition : Nov. 1, 2005-00
1.2.4 Constant Communication Cycle Time
YHLS features a constant communication cycle time, not affected by automatic
participation or withdrawal of slave units, thus delivering reliable communications with
constant cycle time under all circumstances.
1.2.5 Control of YHLS Output States when CPU Stops
If the sequence CPU module switches to STOP mode, the YHLS master module also
stops communications with the slave units. The YHLS master module can be used to
configure the output control function of each slave unit to either reset or hold its outputs
when the CPU stops.

 Cables
Prepare a plug-cable set that complies with the connector pin assignment described
above. Use cables of the type described below.
 CAT5 shielded cable or equivalent
- Shielded twisted-pair cable
- Impedance: 100 Ω
- Conductor size: AWG24
CAUTION
- If a different type of cable is recommended for a slave unit by its manufacturer, use
that cable instead.
- Commercially available Ethernet cables cannot be used for this purpose because its
connector pin assignment is different from that of the CAT5 cable.
 Connector
Use plugs of the following type:
- RJ-45 shielded modular plug
 Shield Treatment
The cable shield must be treated as follows:
- The cable drain must be connected to pin 8 of the RJ-45 modular plug.
- The cable shield must be connected to the shield of the RJ-45 modular plug.
