•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 when 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 categori

zed in order

of importance to Warning and Caution:

Warning

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

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 2

40V AC, or 24 or 12V DC. Using four optional 16-point I/O modules, the 24-I/O type CPU module
(except 12V DC power type) 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
ma

ximum 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
in

structions — 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 IDE

C’s previous PLCs such as OpenNet Controller and FC4A MicroSmart, your software assets can be

used in the new control system.

• 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 can be downloaded to the CPU module. Memory c

artridge upload is also avai

lable on upgraded CPU

modules with system program version 200 or higher. The upload and download options are selected using WindLDR.

Analog I/O Modules (slim CPU modules and all-in-one 24-I/O types except 12V DC power type)

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 (Pt100, 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.

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 devices 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. Upgraded CPU modules with system program version
210 or higher have an option for read protection without a password, making it possible to inhibit reading completely.

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.

1-4 FC5A MicroSmart User’s Manual FC9Y-B1268

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 st

ored to special data registers. The ana-

log 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 co

ntrol, 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 bui

lt-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 ROM in the CPU module. Since the data in the ROM 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).

System Setup

This section illustrates system setup configurations for using powerful communication functions of the MicroSmart.

User Communication and Modem Communication System

The all-in-one type MicroSmart CPU modules have port 1 for RS232C communication and port 2 connector. An optional
RS232C or RS485 communication adapter can be installed on the port 2 connector. With an RS232C communication
adapter installed on port 2, the MicroSmart CPU module can communicate with two RS232C devices at the same time.

Expansion RS232C/RS485 communication modules (FC5A-SIF2/-SIF4) can also be mounted to the CPU modules to add
port 3 t

o port 5, so that Micr

oSmart CPU module can communicate with more RS232C/RS485 devices at the same time.

The figure below illustrates a system setup of user communication and modem communi

cation. In this example, the
operating status of a remote machine is monitored on a computer through modems connected to port 2 and the data is
transferred through port 1 to a pager transmitter using the user communication.

The same system can be set up using any slim type CPU module and

an optional RS232C communica

tion module.

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 sensor

s, actuators, sw

itches, 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-Int

erface 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 pages 2-78 and 24-1 (Advanced Vol.).

The expansion communication module has four communica

tion functions.

Maintenance Communication
(Computer Link)

When a MicroSmart CPU module is connected to a computer, operating status and I/O status
c

an be monitor

ed on the computer, data in the CPU can be monitored or updated, and user

programs can be downloaded and uploaded. Run-time program download cannot be used.

User Communication

CPU modules can be linked to remote RS232C or RS485 devices such as computers, printers,
and

barcode reade

rs through expansion communication modules, using the user communica-

tion function.

Data Link (Note)

All MicroSmart CPU modules can set up a data link system. One CPU module at the master sta­tion can communicate with 31 slave stations through an RS485 line to exchange data and per­form distributed control effectively.

Modbus Communication (Note)

All MicroSmart CPU modules can be used as a Modbus master or slave, and can be connected
to other Modbus devices

.

Note: CPU modules with system program version 220 or higher and FC5A-SIF4 are

needed to use data link or Modbus communication.

For the combination of the version numbers and supported protocols, see page A-17.

Analog I/O Modules

Analog I/O modules are available in 3-I/O types, 2-, 4-, and 8-input types, and 1-, 2- and 4-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 every 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 macro is executed, so analog I/O parameters can be
changed while the CPU is running.

Power Supply for Analog I/O Modules

When supplying power to the analog I/O modules, take the following considerations.

•

Power Supply for FC4A-L03A1, FC4A-L03AP1, FC4A-J2A1, FC4A-K1A1, and FC4A-K4A1

Use separate power supplies for the MicroSmart CPU module and FC4A-L03A1, FC4A-L03AP1, FC4A-J2A1, FC4A-K1A1,
and FC4A-K4A1. Power up the analog I/O modules at least 1 second earlier than the CPU module. This is recommended
to ensure correct operation of the analog I/O control.

Note: When re-powering up the analog I/O modules FC4A-L03A1, -L03AP1, and -J2A1, a time interval is needed before turning on
these modules. If a single power supply is used for the MicroSmart CPU module and the analog I/O modules, turn on the analog I/O
modules at least 5 seconds (at 25°C) after turning off these modules. If separate power supplies are used for the MicroSmart CPU mod­ule and the analog I/O modules, turn on the analog I/O modules at least 30 seconds (at 25°C) after turning off the analog I/O modules
whether the CPU m

odule is powered up or not.

• Power Supply for FC4A-J4CN1, FC4A-J8C1, FC4A-J8AT1, and FC4A-K2C1
Use the same power supply for the MicroSmart CPU module and FC4A-J4CN1, FC4A-J8C1, FC4A-J8AT1, and FC4A-K2C1 to
suppress the influence of noises.

After the CPU module has started to run, ladder refresh type analog input modul

es perform initialization for a maximum
of 5 seconds. During this period, the analog input data have an indefinite value. Design the user program to make sure
that the analog input data are read to the CPU module after the analog input operating status has changed to 0 (normal
operation). For the analog input operating status, see page 9-14.

Wiring Analog I/O Lines

Separate the analog I/O lines, particularly resistance thermometer inputs, from motor lines as much as possible to sup­press the influence of noises.

(FC4A-AS62M) and/or expansion RS232C/RS485 communication module (FC5A-SIF2 or FC5A-SIF4). When using these modules in com­bination with analog I/O modules, use the slim type CPU module.

Wiring 2-Wire Analog Current Output Devices

To use an analog input module with a 2-wire analog device, wire the analog device in series with a separate 24V DC
power supply.

Expansion Interface Module

Slim type CPU modules can normally connect a maximum of seven I/O modules. Using the expansion interface module
makes it possible to connect additional eight I/O modules to expand another 256 I/O points. The maximum number of I/
O points is 512, including the I/Os in the CPU module.

Expansion interface modules are available in two mounting s

tyles: for i

ntegrated mounting and separate mounting.

For the integrated mounting, expansion interface module FC5A-EXM2 is mounted next to the seventh I/O module and
more I/O modules are mounted ne

xt to the expansion interface module.

For the separate mounting, expansion interface master module FC5A-EXM1M an

d expansion interface slave module
FC5A-EXM1S are used. The expansion interface master module is mounted at the end of I/O modules, the expansion
interface slave module is used at the beginning of the other I/O modules, and the master and slave modules are con­nected with expansion interface cable FC5A-KX1C.
