PREFACE-1

SAFETY PRECAUTIONS

• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the FC4A series MicroSmart analog I/O modules.

• All MicroSmart modules are manufactured under IDEC’s rigorous quality control system, but users must add a backup or
failsafe provision to the control system using the MicroSmart in applications where heavy damage or personal injury may
be caused in case the MicroSmart should fail.

• In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:

•Turn of

f the power to the

MicroSmart before starting installation, removal, wiring, maintenance, and inspection of the

MicroSmart. Failure to turn power off may cause electrical shocks or fire hazard.

• Special expertise is required to install, wire, program, and operate the MicroSmart. People without such expertise must not
use the MicroSmart.

• Emergency stop and interlocking circuits must be configured outside the MicroSmar t. If such a circuit is configured inside
the MicroSmart, failure of the MicroSmart may cause disorder of the control system, damage, or accidents.

• Install the MicroSmart according to the instructions described in this user’s manual. Improper installation will result in fall­ing, failure, or malfunction of the MicroSmart.

• The MicroSmart is designed for installation in a cabinet. Do not install the MicroSmart outside a cabinet.

• Install the MicroSmart in environments described in this user’s manual. If the MicroSmart is used in places where the

MicroSmart is subjected to high-temperature, high-humidity, condensation, corrosive gases, excessive vibrations, and

excessive shocks, then electrical shocks, fire hazard, or malfunction will result.

• The environment for using the MicroSmar t is “Pollution degree 2.” Use the MicroSmar t in environments of pollution
degree 2 (according to IEC 60664-1).

• Prevent the MicroSmar t from falling while moving or transporting the MicroSmart, otherwise damage or malfunction of
the MicroSmart will result.

• Prevent metal fragments and pieces of wire from dropping inside the MicroSmart housing. Put a cover on the MicroSmart
modules during installation and wiring. Ingress of such fragments and chips may cause fire hazard, damage, or malfunc­tion.

• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.

• Use an IEC 60127-approved fuse on the power line outside the MicroSmart. This is required when equipment containing
the MicroSmart is destined for Europe.

• Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the MicroSmart is des­tined for Europe.

• Use an EU-approved circuit breaker. This is required when equipment containing the MicroSmart is destined for Europe.

• Make sure of safety before starting and stopping the MicroSmart or when operating the MicroSmar t to force outputs on or
off. Incorrect operation on the MicroSmart may cause machine damage or accidents.

• If relays or transistors in the MicroSmart output modules should fail, outputs may remain on or off. For output signals
which may cause heavy accidents, provide a monitor circuit outside the MicroSmart.

• Do not connect the ground wire directly to the MicroSmart. Connect a protective ground to the cabinet containing the

MicroSmart using an M4 or larger screw. This is required when equipment containing the MicroSmar t is destined for

Europe.

• Do not disassemble, repair, or modify the MicroSmart modules.

• When disposing of the MicroSmart, do so as an industrial waste.

Warning

Warning notices are used to emphasize that improper operation may cause
severe personal injury or death.

Caution

Caution notices are used where inattention might cause personal injury or
damage to equipment.

1: GENERAL INFORMATION

Introduction

This chapter describes general information and specifications of the FC4A series MicroSmart analog I/O modules.

About the Analog I/O Modules

Analog I/O modules are available in 3-I/O types, 2-, 4-, and 8-input types, and 1- and 2-output types. The input channel
can accept voltage and current signals, thermocouple and resistance thermometer signals, or thermistor signals. The output
channel generates voltage and current signals.

END Refresh Type and Ladder Refresh Type

Depending on the internal circuit design for data refreshing, analog I/O modules are categorized into two types.

END Refresh Type

Each END refresh type analog I/O module is allocated 20 data registers to store analog I/O data and parameters for controlling
analog I/O operation. These data registers are updated at ever y end processing while the CPU module is running. WindLDR has
ANST macro to program the analog I/O modules.

The CPU module checks the analog I/O configuration only once at the end processing in the first scan. If you have changed the
parameter while the CPU is running, stop and restart the CPU to enable the new parameter.

Ladder Refresh Type

Each ladder refresh type analog I/O module can be allocated any data registers to store analog I/O data and parameters for con­trolling analog I/O operation. The data registers are programmed in the ANST macro. Analog I/O data are updated at the ladder
step following the ANST macro. Analog I/O parameters are updated when the ANST macr o is executed, so analog I/O parame­ters can be changed while the CPU is running.

Applicable CPU Modules and WindLDR Version

END refresh type analog I/O modules as many as listed below can be used with any FC4A and FC5A MicroSmart CPU
modules and WindLDR versions.

Ladder refresh type analog I/O modules can be used with the FC4A and FC5A MicroSmart CPU module system program
versions and WindLDR versions as listed below.

All-in-one 10- and 16-I/O type CPU modules cannot use either END refresh or ladder refresh type analog I/O modules.

Note: FC5A all-in-one 24-I/O type CPU modules cannot use analog I/O modules in combination with the AS-Interface master
module (FC4A-AS62M) and/or expansion RS232C communication module (FC5A-SIF2). When using these modules in combi­nation with analog I/O modules, use the slim type CPU module.

Confirming System Program Version

The system program version can be confirmed using WindLDR.

1. Connect a PC to communication port 1 or 2 on the MicroSmar t CPU module using the computer link cable 4C
(FC2A-KC4C).

2. From the WindLDR menu bar, select Online > Monitor. The monitor mode is enabled.

3. From the WindLDR menu bar, select Online > PLC Status. The PLC Status dialog box appears and shows the sys-

tem program version.

Analog Output Specifications

Note 1: Total input system transfer time = Sample repetition time + Internal processing time

When using the FC4A-J4CN1, FC4A-J8C1, or FC4A-J8AT1, the total input system transfer time increases in proportion to the
number of channels used.

Note 2: The data processed in the analog I/O module can be linear-converted to a value between –32768 and 32767. The
optional range designation, and analog I/O data minimum and maximum values can be selected using data registers allo­cated to analog I/O modules. See page 4-12.

Note 3: When an error is detected, a corresponding error code is stored to a data register allocated to analog I/O operating
status. See page 4-6.

Note 4: The value is measured when a 500V clamp voltage is applied to the power supply and I/O lines.

• Connect a fuse appropriate for the applied voltage and current draw, at the position shown in the

diagram. This is required when equipment containing the MicroSmar t is destined for Europe.

• Do not connect any wiring to unused terminals.

• Before turn on the power, make sure that wiring to the analog I/O module is correct. If wiring is

incorrect, the analog I/O module may be damaged.
