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).
