1. DESIGN PRECAUTIONS
• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during
external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for
opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all outputs
are turned off. Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control
block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
3) If an overload of the 24 V DC service power supply occurs, the voltage automatically drops, inputs in the PLC
are disabled, and all outputs are turned off.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
4) Note that when an error occurs in a relay or transistor output device, the output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to
ensure safe machinery operation in such a case.
• Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the
control line at least 100 mm (3.94") or more away from the main circuit or power line.
Noise may cause malfunctions.
• Install module so that excessive force will not be applied to peripheral device connectors.
Failure to do so may result in wire damage/breakage or PLC failure.

FX3S Series Programmable Controllers
User's Manual - Hardware Edition
Caution for compliance with EC Directive
1. Installation in Enclosure
Programmable logic controllers are open-type devices that must be installed and used within conductive
control boxes. Please use the FX
shielded control boxes. Please secure the control box lid to the control box (for conduction). Installation within
a control box greatly affects the safety of the system and aids in shielding noise from the programmable logic
controller.
2. Caution for Analog Products in use
The analog products have been found to be compliant to the European standards in the aforesaid manual
and directive. However, for the very best performance from what are in fact delicate measuring and controlled
output devices, Mitsubishi Electric would like to make the following points;
As analog devices are sensitive by nature, their use should be considered carefully. For users of proprietary
cables (integral with sensors or actuators), these users should follow those manufacturers' installation
requirements.
Mitsubishi Electric recommends that shielded cables be used. If NO other EMC protection is provided, users
may experience temporary loss or accuracy between +10% / -10% in very heavy industrial areas.
However, Mitsubishi Electric suggests that if adequate EMC precautions are followed for the users complete
control system.
- Sensitive analog cables should not be laid in the same trunking or cable conduit as high voltage cabling.
Where possible, users should run analog cables separately.
- Good cable shielding should be used. When terminating the shield at Earth - ensure that no earth loops
are accidentally created.
- When reading analog values, EMC accuracy can be improved by averaging the readings. This can be
achieved either through functions on the analog product or through a user's program in the FX
PLC main unit.

DESIGN PRECAUTIONS
• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during external power supply
problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements
(such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower
positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all outputs are turned off.
Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be
disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
3) If an overload of the 24 V DC service power supply occurs, the voltage automatically drops, inputs in the PLC are disabled, and all
outputs are turned off.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
4) Note that when an error occurs in a relay or transistor output device, the output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.

Procedures
DESIGN PRECAUTIONS
• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during external power supply
problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements
(such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower
positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all outputs are turned off.
Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be
disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
3) If an overload of the 24 V DC service power supply occurs, the voltage automatically drops, inputs in the PLC are disabled, and all
outputs are turned off.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
4) Note that when an error occurs in a relay or transistor output device, the output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.
DESIGN PRECAUTIONS
• Do not bundle the control line together with or lay it close to the main circuit or power line. As a guideline, lay the control line at least
100 mm (3.94") or more away from the main circuit or power line.
Noise may cause malfunctions.
• Install module so that excessive force will not be applied to peripheral device connectors.
Failure to do so may result in wire damage/breakage or PLC failure.

Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be
disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
3) If an overload of the 24 V DC service power supply occurs, the voltage automatically drops, inputs in the PLC are disabled, and all
outputs are turned off.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
4) Note that when an error occurs in a relay or transistor output device, the output could be held either on or off.
For output signals that may lead to serious accidents, external circuits and mechanisms should be designed to ensure safe
machinery operation in such a case.

9.1Before Starting Input Wiring
9.1.1Sink and source input
The input terminals (X) of the main unit are common to sink/source input of 24 V DC internal power.
1. Differences between the sink input circuit and the source input circuit
• Sink input [-common]
Sink input means a DC input signal with current-flow from the input
(X) terminal. When a sensor with a transistor output is connected,
NPN open collector transistor output can be used.
• Source input [+common]
Source input means a DC input signal with current-flow into the input
(X) terminal. When a sensor with a transistor output is connected,
PNP open collector transistor output can be used.

2. Method of switching between sink/source input
To switch the input type to sink or source input, wire the [S/S] terminal to the [0V] or [24V] ([-] or [+]) terminal.
• In the case of AC power type
- Sink input: [24V] terminal and [S/S] terminal are connected.
- Source input: [0V] terminal and [S/S] terminal are connected.
For wiring examples, refer to Subsection 9.2.3.
• In the case of DC power type
- Sink input: [+] terminal and [S/S] terminal are connected.
- Source input: [-] terminal and [S/S] terminal are connected.
For wiring examples, refer to Subsection 9.2.4.
3. Cautions for using
Mixed use of sink/source inputs.
It is possible to set all input terminals (X) of the main unit to either sink input or source input mode.
However, a mixture of sink and source input terminals cannot be set within a single unit.
Differences from FX1S PLCs in input specifications (reference)
Sink input type only FX
(manuals in English are supplied) have different model names.
• For sink input type only FX

Introduction
These counters are 32-bit up-count/down-count binary counters.
Examples of program
1) For C235
• C235 counts the number of times the input terminal X000
switches from OFF to ON while X012 is on.
• While X011 is on, the counter resets when RST instruction
is executed.
• The counters C235 to C245 switch to the down-count or upcount mode by turning on or off M8235 to M8245.
2) For C244
• C244 starts counting immediately when the input terminal
X006 turns on while X012 is on. The count input terminal is
X000. The setting for this example is the data of the
indirectly designated data register (D1, D0).
• C244 can be reset by X011 on the sequence. For C244,
X001 is allocated as the external reset input. The counter
resets immediately when X001 turns on.
• The counters C235 to C245 switch to the down-count or upcount mode by turning on or off M8235 to M8245.

User's Manual - Hardware Edition
• C235 is set to the up-count or down-count mode through interruption by the count input X000.
• When the current value increases from -6 to -5, the output contact is set, and when the value decreases
from -5 to -6, it is reset.
• The current value increases and decreases regardless of the operation of the output contact. However,
when the counter’s value increments from 2,147,483,647, it changes to -2,147,483,648. In the same
manner, when it decrements from -2,147,483,648, it changes to 2,147,483,647. (This type of counter is
called a ring counter.)
• When RST instruction is executed after the reset input X011 turns on, the current counter's value resets to
0, and the output contact is restored.
• The current value, output contact operation and reset status of counters are backed up (kept) even if the
power is turned off.
10.5.21-phase 2-count input
These counters are 32-bit up-count/down-count binary counters.
The operations of the output contact according to the current value are the same as those of the abovementioned 1-phase 1-count input high-speed counters.

10 Use of High-speed Counters
10.5 Handling of High-speed Counters
• While X012 is on, C246 increments the value when the
input terminal X000 switches from OFF to ON and
decrements the value when the input terminal X001
switches from OFF to ON.
• The down-count/up-count operations of C246 to C250 can
be monitored through the ON/OFF operations of M8246 to
M8250.
2) For C249
ON : Down-counting
OFF: Up-counting
• While X012 is on, C249 starts counting immediately when
the input terminal X006 turns on. The up-counting input
terminal is X000, and the down-counting input terminal is
X001.
• C249 can be reset on the sequence by X011. For C249,
X002 is allocated as reset input. When X002 turns on, C249
is immediately reset.
• The down-count/up-count operations of C246 to C250 can
be monitored through the ON/OFF operations of M8246 to
M8250.

• While X012 is on, C251 counts the operation of the input
terminals X000 (A-phase) and X001 (B-phase) through
interruption.
• While X011 is turned on, the counter is reset when RST
instruction is executed.
• When the current value exceeds the setting, Y002 turns on, and
when the current value becomes lower than the setting, Y002
turns off.
• Y003 turns on (down-count) or off (up-count) according to the
counting direction.

• C254 starts counting immediately when the input terminal X006
is turned on while X012 is on. The count input terminals are
X000 (A-phase) and X001 (B-phase).
• C254 is reset by X011 on the sequence, and it is reset
immediately when X002 is turned on.
• When the current value exceeds the setting (D1, D0), Y004
operates, and when the current value becomes lower than the
setting, Y004 turns off.
• Y005 turns on (down-count) or off (up-count) according to the
counting direction.
• A 2-phase encoder generates A-phase output and B-phase output between which there is a 90 phase
difference. The high-speed counter automatically counts up or down according to the output as shown
below.
• The down-count/up-count operations of C251 to C255 can be monitored through the ON/OFF operations
of M8251 to M8255.

10.6 Timing of Updating of Current Value and Comparison of Current Value
10 Use of High-speed Counters
10.6Timing of Updating of Current Value and Comparison of Current Value
10.6.1Timing of updating of current value
When pulses are input to an input terminal for a high-speed counter, the high-speed counter executes upcounting or down-counting. The current values of devices are updated when counting is input.
10.6.2Comparison of current value
To compare and output the current value of a high-speed counter, the following two methods are available.
1. Use of comparison instruction (CMP instruction), band comparison instruction
(ZCP instruction) or contact comparison instruction
Use the comparison instruction (CMP instruction), band comparison instruction (ZCP instruction) or contact
comparison instruction if the comparison result is necessary at counting. Use these instructions only when
high-speed processing is not required because these instructions are processed in the operation cycle of the
PLC, and operation delay is generated before the comparison output result is obtained. Use the comparison
instructions for high-speed counters (HSCS instruction, HSCR instruction and HSZ instruction) described
below if it is necessary to execute comparison and change the output contact (Y) at the same time when the
current values of high-speed counters change.
2. Use of Comparison instruction for high-speed counters
(HSCS instruction/HSCR instruction/HSZ instruction)
Comparison instructions for high-speed counters (HSCS instruction, HSCR instruction and HSZ instruction)
perform comparison and output the comparison results with the relevant high-speed counting operation.
These instructions have limitations on the number of simultaneously driven instructions as shown in the
following table.
When the output relay (Y) has been designated for comparison results, the ON/OFF status of the output is
affected directly until the END instruction output is refreshed.
When the PLC is a relay output type, a mechanical delay in operation (approx. 10 ms) is caused.
Therefore, it is best to use a transistor output type PLC.
