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 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
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 OpenNet Controller and FC4A MicroSmart, your software assets can be
used in the new control system.

modules can be used with a maximum of five expansion RS232C/RS485 communication modules to expand up to seven
communication ports. Expansion RS232C/RS485 communication modules can be used for computer link communication,
user communication, data link, and Modbus communication.
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 device 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 pro-
gram in the CPU module is restored after removing the memory cartridge.
The user program can be downloaded to the CPU module. Memory cartridge upload is also available 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 volt-
age (0 to 10V DC or –10 to +10V DC) and current (4 to 20 mA) signals.
AS-Interface Master Module (slim CPU modules and all-in-one 24-I/O types except 12V DC power type)
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.

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, run-
time 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 mod-
ifications to the user program and confirm the changes while the CPU is running.

1: GENERAL INFORMATION
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 potenti-
ometers. The values (0 through 255) set with analog potentiometers 1 and 2 are stored 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 ter-
minals 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 (propor-
tional, 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 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 to port 5, so that MicroSmart 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 communication. 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 communication module.
