SAFETY PRECAUTIONS

• Read this user’s manual to make sure of correct operation before starting installation, wiring, operation, maintenance, and
inspection of the MicroSmart.

• 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:

Warning

•Turn off 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 MicroSmart. 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.

Caution

• 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 MicroSmart is “Pollution degree 2.” Use the MicroSmart in environments of pollution
degree 2 (according to IEC 60664-1).

• Prevent the MicroSmart 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.

• Dispose of the battery in the MicroSmart modules when the battery is dead in accordance with pertaining regulations.
When storing or disposing of the battery, use a proper container prepared for this purpose. This is required when equipment
containing the MicroSmart is destined for Europe.

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

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

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

1: GENERAL INFORMATION

Introduction

This chapter describes general information about the powerful capabilities of the upgraded FC5A series MicroSmart micro
programmable logic controllers and system setups to use the MicroSmart in various ways of communication.

About the MicroSmart

IDEC’s FC5A MicroSmart is an upgraded family of micro programmable logic controllers available in two styles of CPU
modules; all-in-one and slim types.

The all-in-one type CPU module has 10, 16, or 24 I/O terminals and is equipped with a built-in universal power supply to
operate on 100 to 240V AC or 24V DC. Using four optional 16-point I/O modules, the 24-I/O type CPU module can
expand the I/O points up to a total of 88 points. Program capacity of the all-in-one type CPU modules is 13,800 bytes
(2,300 steps) on the 10-I/O type CPU module, 27,000 bytes (4,500 steps) on the 16-I/O type, and 54,000 bytes (9,000
steps) on the 24-I/O type.

The slim type CPU module has 16 or 32 I/O terminals and operates on 24V DC. The total I/O points can be expanded to a
maximum of 512. When using two AS-Interface master modules, a maximum of 1,380 I/O points can be connected. The
program capacity of slim type CPU modules is 62,400 bytes (10,400 steps).

Slim type CPU modules feature Logic Engine for superior ladder processing capabilities to achieve fast execution of
instructions — 0.056 µs for a basic instruction (LOD) and 0.167 µs for an advanced instruction (MOV).

User programs for the MicroSmart can be edited using WindLDR on a Windows PC. Since WindLDR can load existing user
programs made for IDEC’s previous PLCs such as all FA series, MICRO-1, MICRO3, MICRO
well as the FC4A MicroSmart, your software assets can be used in the new control system.

HMI Module (all CPU modules)

Used for computer link 1:1 communication, user communication, and modem
communication.

Available in mini DIN connector and terminal block styles. Used for computer link
1:1 or 1:N communication, user communication, data link communication, and
Modbus communication.

An optional HMI module can be installed on any all-in-one type CPU module, and also on the HMI base module mounted
next to any slim type CPU module. The HMI module makes it possible to manipulate the RAM data in the CPU module
without using the Online menu options in WindLDR.

HMI module functions include:

• Displaying timer/counter current values and changing timer/counter preset values

• Displaying and changing data register values

• Setting and resetting bit operand statuses, such as inputs, outputs, internal relays, and shift register bits

• Displaying and clearing error data

• Starting and stopping the PLC

• Displaying and changing calendar/clock data (only when using the clock cartridge)

• Confirming changed timer/counter preset values

Clock Cartridge (all CPU modules)

An optional clock cartridge can be installed on the CPU module to store real time calendar/clock data for use with
advanced instructions to perform time-scheduled control.

Memory Cartridge (all CPU modules)

A user program can be stored on an optional memory cartridge using WindLDR. The memory cartridge can be installed on
another CPU module to replace user programs without the need for connecting to a computer. The original user program in
the CPU module is restored after removing the memory cartridge. The user program on the memory cartridge can also be
downloaded to the CPU module. The download option is selected using WindLDR.

Analog I/O Modules (all CPU modules except all-in-one 10- and 16-I/O types)

The analog input channel can accept either voltage (0 to 10V DC) and current (4 to 20 mA) signals or thermocouple (types
K, J, and T) and resistance thermometer (Pt 100, Pt1000, Ni100, and Ni1000) signals. The output channel generates volt­age (0 to 10V DC or –10 to +10V DC) and current (4 to 20 mA) signals.

AS-Interface Master Module (all CPU modules except all-in-one 10- and 16-I/O types)

One or two AS-Interface master modules can be mounted to communicate with a maximum of 124 slaves, or 496 inputs
and 372 outputs, such as actuators and sensors, through the AS-Interface bus.

Web Server Unit (all CPU modules)

The web server unit is used to connect the MicroSmart to Ethernet. Remote monitoring is made possible, sending Email
messages to personal computers or mobile phones.

1: GENERAL INFORMATION

Special Functions

The MicroSmart features various special functions packed in the small housing as described below. For details about these
functions, see the following chapters.

Stop and Reset Inputs

Any input terminal on the CPU module can be designated as a stop or reset input to control the MicroSmart operation.

RUN/STOP Selection at Startup when “Keep” Data is Broken

When data to be kept such as “keep” designated counter values are broken while the CPU is powered down, the user can
select whether the CPU starts to run or not to prevent undesirable operation at the next startup.

“Keep” or “Clear” Designation of CPU Data

Internal relays, shift register bits, counter current values, and data register values can be designated to be kept or cleared
when the CPU is powered down. All or a specified range of these operands can be designated as keep or clear types.

High-speed Counter

The MicroSmart has four built-in high-speed counters to count high-speed pulses which cannot be counted by the normal
user program processing. All-in-one type CPU modules can count up to 65,535 pulses at 50 kHz. Slim type CPU modules
can count up to 4,294,967,295 pulses at 100 kHz. Both CPU modules can use either single-phase or two-phase high-speed
counters. The high-speed counters can be used for simple positioning control and simple motor control.

Frequency Measurement

The pulse frequency of input signals to four input terminals can be counted using the high-speed counter function at a
maximum of 50 kHz (all-in-one type CPU modules) or 100 kHz (slim type CPU modules).

Catch Input

Four inputs can be used as catch inputs. The catch input makes sure to receive short input pulses from sensors without
regard to the scan time — rising and falling pulse widths of 40 µs and 150 µs (all-in-one type CPU modules) or 5 µs and 5
µs (slim type CPU modules).

Interrupt Input

Four inputs can be used as interrupt inputs. When a quick response to an external input is required, such as positioning
control, the interrupt input can call a subroutine to execute an interrupt program.

Timer Interrupt

In addition to the interrupt input, all CPU modules have a timer interrupt function. When a repetitive operation is required,
the timer interrupt can be used to call a subroutine repeatedly at predetermined intervals of 10 through 140 ms.

Input Filter

The input filter can be adjusted for eight inputs to reject input noises. Selectable input filter values to pass input signals are
0 ms, and 3 through 15 ms in 1-ms increments. The input filter rejects inputs shorter than the selected input filter value
minus 2 ms. This function is useful for eliminating input noises and chatter in limit switches.

User Program Read/Write Protection

The user program in the CPU module can be protected against reading and/or writing by including a password in the user
program. This function is effective for security of user programs.

Constant Scan Time

The scan time may vary whether basic and advanced instructions are executed or not depending on input conditions to
these instructions. When performing repetitive control, the scan time can be made constant by entering a required scan
time value into a special data register reserved for constant scan time.

Online Edit, Run-Time Program Download, and Test Program Download

Normally, the CPU module has to be stopped before downloading a user program. All CPU modules have online edit, run­time program download, and test program download capabilities to download a user program containing small changes
while the CPU is running in either 1:1 or 1:N computer link system. This function is particularly useful to make small
modifications to the user program and confirm the changes while the CPU is running.

FC5A MICROSMART USER’S MANUAL 1-3

1: GENERAL INFORMATION

Analog Potentiometer

All CPU modules have an analog potentiometer, except the all-in-one 24-I/O type CPU module has two analog potentiom­eters. The values (0 through 255) set with analog potentiometers 1 and 2 are stored to special data registers. The analog
potentiometer can be used to change the preset value for a timer or counter.

Analog Voltage Input

Every slim type CPU module has an analog voltage input connector. When an analog voltage of 0 through 10V DC is
applied to the analog voltage input connector, the signal is converted to a digital value of 0 through 255 and stored to a spe­cial data register. The data is updated in every scan.

Pulse Output

Slim type CPU modules have pulse output instructions to generate high-speed pulse outputs from transistor output termi­nals used for simple position control applications, illumination control, trapezoidal control, and zero-return control.

PID Control

All CPU modules (except the all-in-one 10- and 16-I/O types) have the PID instruction, which implements a PID (propor­tional, integral, and derivative) algorithm with built-in auto tuning or advanced auto tuning to determine PID parameters.
This instruction is primarily designed for use with an analog I/O module to read analog input data, and turns on and off a
designated output to perform PID control in applications such as temperature control. In addition, the PID instruction can
also generate an analog output using an analog I/O module.

Expansion Data Register

Slim type CPU modules have expansion data registers D2000 through D7999. Numerical data can be set to expansion data
registers using WindLDR. When downloading the user program, the preset values of the expansion data registers are also
downloaded to the EEPROM in the CPU module. Since the data in the EEPROM is non-volatile, the preset values of the
expansion data registers are maintained semi-permanently and loaded to the RAM each time the CPU is powered up.

32-bit and Floating Point Data Types

Some advanced instructions can select 32-bit data types from D (double word), L (long), and F (float) in addition to W
(word) and I (integer).

AS-Interface Network

Actuator-Sensor-Interface, abbreviated AS-Interface

The MicroSmart can be connected to the AS-Interface network using the AS-Interface master module (FC4A-AS62M).

AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a
network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer. A master
device can communicate with slave devices such as sensors, actuators, and remote I/Os, using digital and analog signals
transmitted over the AS-Interface bus.

The AS-Interface system is comprised of the following three major components:

• One master, such as the MicroSmart AS-Interface master module

• One or more slave devices, such as sensors, actuators, switches, and indicators

• Dedicated 30V DC AS-Interface power supply (26.5 to 31.6V DC)

These components are connected using a two-core cable for both data transmission and AS-Interface power supply. AS­Interface employs a simple yet efficient wiring system and features automatic slave address assignment function, while
installation and maintenance are also very easy.

For details about AS-Interface communication, see a separate user’s manual for the MicroSmart AS-Interface master mod-
ule (manual No. FC9Y-B644).
