1: GENERAL INFORMATION
Introduction
This chapter describes general information for understanding the MicroSmart’s powerful capabilities and system setups to
use the MicroSmart in various ways of communication.
About the MicroSmart
IDEC’s MicroSmart is a new family of micro programmable logic controllers available in two styles of CPU modules; allin-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 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. The slim type CPU module has 20 or 40 I/O terminals and
operates on 24V DC. The total I/O points can be expanded to a maximum of 264.
User programs for the MicroSmart can be edited using WindLDR on a Windows PC. Since WindLDR can load e xisting user
programs made for IDEC’s previous PLCs such as all FA series, MICRO-1, MICRO3, MICRO
your software assets can be used in the new control system.
Program capacity of the all-in-one type CPU modules is 4,800 bytes (800 steps) on the 10-I/O type CPU module, 15,000
bytes (2,500 steps) on the 16-I/O type, and 27,000 bytes (4,500 steps) on the 24-I/O type. Slim type CPU modules have a
program capacity of 27,000 bytes (4,500 steps) or 31,200 bytes (5,200 steps). When using an optional 64KB memory cartridge on slim type CPU modules, the program capacity can be expanded up to 64,500 bytes (10,750 steps).

In addition to the standard RS232C port 1, the all-in-one 16- and 24-I/O type CPU modules feature a port 2 connector to
install an optional RS232C or RS485 communication adapter. All slim type CPU modules can be used with an optional
RS232C or RS485 communication module to add communication port 2. With an optional HMI base module mounted
with a slim type CPU module, an optional RS232C or RS485 communication adapter can also be installed on the HMI
base module.
can be monitored on the computer, data in the CPU can be monitored or updated, and user
programs can be downloaded and uploaded. All CPU modules (except the all-in-one 10-I/O
type) can set up a 1:N computer link system to connect a maximum of 32 CPU modules to a
computer.
All MicroSmart CPU modules can be linked to external RS232C devices such as computers,
printers, and barcode readers, using the user communication function. RS485 user communication is also available on upgraded CPU modules of slim 20-I/O relay output and 40-I/O
types.
All MicroSmart CPU modules (except the all-in-one 10-I/O type) can communicate through
modems using the built-in modem protocol.
All MicroSmart CPU modules (except the all-in-one 10-I/O type) 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 ef fectively.

1: GENERAL INFORMATION
HMI Module (all CPU modules)
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 from a computer , and the memory cartridge
can be installed on another CPU module to replace user programs without the need for connecting to a computer.
Analog I/O Modules (all CPU modules except the all-in-one 10- and 16-I/O types)
Analog I/O modules are available in 3-I/O types, 2-input type, and 1-output type. The 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) signals. The output channel generates voltage (0 to 10V DC) and current (4 to 20 mA) signals.
AS-Interface Master Module (slim type 20-I/O relay output and 40-I/O types)
Four upgraded slim type CPU modules (FC4A-D20RK1, FC4A-D20RS1, FC4A-D40K3, and FC4A-D40S3) with system
program ver . 201 and higher can use the AS-Interface master module, and hav e additional internal relays and data registers
to communicate with slaves, such as actuators and sensors, through the AS-Interface bus. For details about AS-Interface
communication, see a separate user’s manual for the MicroSmart AS-Interface master module (manual No. FC9Y-B644).
Special Functions
The MicroSmart features various special functions packed in the small housing as described belo w. 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 make it possible to count up to 65,535 (FFFFh) high-speed pulses
which cannot be counted by the normal user program processing. One high-speed counter (all-in-one type CPU modules)
or two high-speed counters (slim type CPU modules) can be used as either two-phase or single-phase high-speed counters
at a maximum count input frequency of 20 kHz. Three or two others are single-phase high-speed counters with a maximum counting frequency of 5 kHz. The high-speed counters can be used for simple positioning control and simple motor
control.

1: GENERAL INFORMATION
Catch Input
Four inputs can be used as catch inputs. The catch input makes sure to recei ve short input pulses (rising pulse of 40 µsec or
falling pulse of 150 µsec minimum) from sensors without regard to the scan time.
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, slim type CPU modules FC4A-D20RK1, FC4A-D20RS1, FC4A-D40K1, and FC4AD40S1 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 msec.
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 msec, and 3 through 15 msec in 1-msec increments. The input filter rejects inputs shorter than the selected input filter
value minus 2 msec. 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.
Partial Program Download
Normally, the CPU module has to be stopped before downloading a user program. All CPU modules (except the all-in-one
10-I/O type) have run-time program download capabilities to do wnload 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.
Analog Potentiometer
All CPU modules have an analog potentiometer , e xcept the all-in-one 24-I/O type CPU module has tw o 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 v alue 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 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 FC4A-D20RK1, FC4A-D20RS1, FC4A-D40K3, and FC4A-D40S3 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 v alues of the e xpansion data registers are maintained semi-permanently
and loaded to the RAM each time the CPU is powered up.

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-Interf ace communication, see a separate user’s manual for the MicroSmart AS-Interface master module (manual No. FC9Y-B644).

Power Supply
All-in-One Type CPU Module (AC and DC Power)
Caution
• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
• The allowable power voltage range is 85 to 264V AC for the AC power type CPU module and
16.0 to 31.2V DC for the DC power type CPU module. Do not use the MicroSmart CPU module
on any other voltage.
• On the AC power type CPU module, if the power voltage turns on or off very slowly between 15
and 50V AC, the CPU module may run and stop repeatedly between these voltages. If failure or
disorder of the control system, damage, or accidents may be caused, provide a measure for prevention using a voltage monitoring circuit outside the MicroSmart.
• 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.
Power Supply Voltage
The allowable power voltage range for the all-in-one type MicroSmart CPU module is 85 to 264V AC for the AC power
type and 16.0 to 31.2V DC for the DC power type.
Power failure detection voltage depends on the quantity of used input and output points. Basically, power failure is
detected when the power voltage drops below 85V AC or 16.0V DC, stopping operation to prevent malfunction.
A momentary power interruption for 20 msec or less is not recognized as a power failure at the rated voltage of 100 to
240V AC or 24V DC.
Inrush Current at Powerup
When the all-in-one AC or DC power type CPU module is powered up, an inrush current of a maximum of 35A (10- and
16-I/O type CPU modules) or 40A (24-I/O type CPU module) flows.
Power Supply Wiring
Use a stranded wire of UL1015 AWG22 or UL1007
AWG18 for power supply wiring. Make the power supply
wiring as short as possible.
Run the power supply wiring as far away as possible from
motor lines.
Grounding
To prevent electrical shocks, connect the or terminal
to a proper ground using a wire of UL1007 AWG16. The

Slim Type CPU Module (DC Power)
3: INSTALLATION AND WIRING
Caution
• Use a power supply of the rated value. Use of a wrong power supply may cause fire hazard.
• The allowable power voltage range for the slim type MicroSmart CPU module is 20.4 to 26.4V
DC. Do not use the MicroSmart on any other voltage.
• If the power voltage turns on or off very slo wly between 10 to 15V DC, the MicroSmart may run
and stop repeatedly between these voltages. If failure or disorder of the control system, damage,
or accidents may be caused, provide a measure for prevention using a voltage monitoring circuit
outside the MicroSmart.
• 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.
Power Supply Voltage
The allowable power voltage range for the slim type
MicroSmart CPU module is 20.4 to 26.4V DC.
Power failure detection voltage depends on the quantity of used input and output points. Basically, power failure is
detected when the power voltage drops below 20.4V DC, stopping operation to prevent malfunction.
A momentary power interruption for 10 msec or less is not recognized as a power failure at the rated voltage of 24V DC.
Inrush Current at Powerup
When the slim type CPU module is powered up, an inrush current of a
maximum of 50A flows.
Power Supply Wiring
Use a stranded wire of UL1015 AWG22 or UL1007 AWG18 for power
supply wiring. Make the power supply wiring as short as possible.

4: OPERATION BASICS
Introduction
This chapter describes general information about setting up the basic MicroSmart system for programming, starting and
stopping MicroSmart operation, and introduces simple operating procedures from creating a user program using WindLDR
on a computer to monitoring the MicroSmart operation.
Connecting MicroSmart to PC (1:1 Computer Link System)
The MicroSmart can be connected to a Windows PC in two ways.
Computer Link through Port 1 or Port 2 (RS232C)
When connecting a Windows computer to the RS232C port 1 or port 2 on the MicroSmart CPU module, enable the maintenance protocol for the RS232C port using the Function Area Settings in WindLDR. See page 26-2.
To set up a 1:1 computer link system, connect a computer to the CPU module using the computer link cable 4C (FC2AKC4C). The computer link cable 4C can be connected to port 1 directly. When connecting the cable to port 2 on the all-inone 16- or 24-I/O type CPU module, install an optional RS232C communication adapter (FC4A-PC1) to the port 2 connector. When connecting to port 2 on the slim type CPU module, an optional RS232C communication module (FC4AHPC1) is needed. The RS232C communication adapter can also be installed on the HMI base module (FC4A-HPH1).

When connecting a Windows computer to port 2 on the all-in-one 16- or 24-I/O type CPU module or slim type CPU module, enable the maintenance protocol for port 2 using the Function Area Settings in WindLDR. See page 26-2.
To set up a 1:1 computer link system using the all-in-one 16- or 24-I/O type CPU module, install an optional RS485 communication adapter (FC4A-PC2) to the port 2 connector. Connect a computer to the RS232C/RS485 converter (FC2AMD1) using the RS232C cable (HD9Z-C52). Connect the RS232C/RS485 converter to the CPU module using the user
communication cable 1C (FC2A-KP1C). The RS232C/RS485 converter is powered by an 24V DC source or an AC
adapter with 9V DC output. For details about the RS232C/RS485 converter, see page 26-4.
To set up a 1:1 computer link system using the slim type CPU module, an optional RS485 communication module (FC4AHPC2) is needed. The RS485 communication adapter can also be installed on the HMI base module (FC4A-HPH1).
