SAFETY PRECAUTIONS
Warning notices are used to emphasize that improper operation may cause severe personal injury or death.
Warning
Caution notices are used where inattention might cause personal injury or damage to equipment.
Caution
Read the SmartAXIS Pro/Lite User’s Manual and SmartAXIS Touch User's Manual to make sure of correct operation before starting installation,
wiring, operation, maintenance, and inspection of the SmartAXIS.
All SmartAXIS 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 SmartAXIS in applications where heavy damage or personal injury may be caused in case the SmartAXIS should
fail.
In this user’s manual, safety precautions are categorized in order of importance to Warning and Caution:
The SmartAXIS is not designed for use in medical equipment, nuclear power, railways, aviation, passenger vehicle equipment, or similar
applications requiring a high degree of reliability and safety. The SmartAXIS cannot be used for such applications.
When using the SmartAXIS in applications not described above that require a high degree of reliability in terms of functionality and precision,
appropriate measures such as failsafe mechanisms and redundant mechanisms must be taken for a system containing the SmartAXIS.
Emergency stop and interlocking circuits must be configured outside the SmartAXIS.
If relays or transistors in the SmartAXIS output circuits should fail, outputs may remain in the on or off state. For output signals which may
cause serious accidents, configure monitor circuits outside the SmartAXIS.
The SmartAXIS self-diagnostic function may detect internal circuit or program errors, stop programs, and turn outputs off. Configure circuits so
that the system containing the SmartAXIS is not jeopardized when outputs turn off.
Turn off power to the SmartAXIS before installation, removal, wiring, maintenance, and inspection of the SmartAXIS. Failure to turn power off
may cause electrical shocks or fire hazard.
Special expertise is required to install, wire, program, and operate the SmartAXIS. People without such expertise must not use the SmartAXIS.
Install the SmartAXIS according to the instructions described in SmartAXIS Pro/Lite User's Manual and SmartAXIS Touch User's Manual.
Improper installation will result in falling, failure, or malfunction of the SmartAXIS.
The SmartAXIS is designed for installation in a cabinet. Do not install the SmartAXIS outside a cabinet.
Install the SmartAXIS in environments described in SmartAXIS Pro/Lite User's Manual and SmartAXIS Touch User's Manual. If the SmartAXIS is
used in places where the SmartAXIS 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 SmartAXIS is “Pollution degree 2.” Use the SmartAXIS in environments of pollution degree 2 (according to IEC
60664-1).
While moving or transporting prevent the SmartAXIS from falling, otherwise damage or malfunction of the SmartAXIS will result.
Wiring must use lead sizes that are appropriate for the applied voltage and current. Terminal screws must be tightened with the prescribed
tightening torque.
Prevent metal fragments and pieces of wire from dropping inside the SmartAXIS housing. Put a cover on the SmartAXIS 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 the wrong power supply may cause fire hazard.
Use an IEC 60127-approved fuse on the power line outside the SmartAXIS. This is required when equipment containing the SmartAXIS is
designed for use in Europe.
Use an IEC 60127-approved fuse on the output circuit. This is required when equipment containing the SmartAXIS is designed for use in Europe.
Use an EU-approved circuit breaker. This is required when equipment containing the SmartAXIS is destined for Europe.
Make sure of safety before starting and stopping the SmartAXIS or when operating the SmartAXIS to force outputs on or off. Incorrect operation
of the SmartAXIS may cause machine damage or accidents.
Do not connect the ground wire directly to the SmartAXIS. Connect a protective ground to the cabinet containing the SmartAXIS using an M4 or
larger screw. This is required when equipment containing the SmartAXIS is designed for use in Europe.
Do not disassemble, repair, or modify the SmartAXIS modules.
The SmartAXIS contains electronic parts and batteries. When disposing of the SmartAXIS, do so in accordance
with national and local regulations.

Introduction
This chapter describes device addresses available for the SmartAXIS Pro/Lite to program FBD. Special internal relays and special
data registers are also described.
The SmartAXIS is programmed using devices such as inputs, outputs, remote inputs, remote outputs, internal relays, timers,
counters, shift registers, and data registers.
Inputs (I) are relays to receive input signals through the input terminals.
Remote inputs (I) are relays to receive input signals from external devices connected to the remote I/O slaves.
Outputs (Q) are relays to send the processed results of the user program to the output terminals.
Remote outputs (O) are relays to send output signals to external devices connected to the remote I/O slaves.
Internal relays (M) are relays used in the CPU and cannot be output to the output terminals.
Special internal relays (M) are internal relays dedicated to specific functions.
Timers (T) are relays used in the user program, available as 1-sec, 100-ms, 10-ms, and 1-ms timers.
Counters (C) are relays used in the user program, available as adding counter, reversible counter, and hour meter FBs.
Shift registers (R) are registers to shift the data bits according to pulse inputs.
Data registers (D) are registers used to store numerical data.
Special data registers (D) are dedicated to special functions.
Device Addresses
Available I/O numbers depend on the SmartAXIS type.
