Depending on the circumstances, procedures indicated by may also cause severe injury. It is important to follow all precautions for personal safety. Store this manual in a safe place so that it can be taken out and read whenever necessary. Always forward it to the end user.
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.

3. WIRING PRECAUTIONS
Reference
• Make sure to cut off all phases of the power supply externally before attempting installation or wiring work. Failure to do so may cause electric shock or damage to the product.
• Make sure to attach the terminal cover, offered as an accessory, before turning on the power or initiating operation after installation or wiring work. Failure to do so may cause electric shock.
• Do not supply power to the [24V] terminal (24 V DC service power supply) on the main unit. Doing so may cause damage to the product.
• Perform class D grounding (grounding resistance: 100 or less) to the grounding terminal on the main unit with a
wire 2 mm2 or thicker. Do not use common grounding with heavy electrical systems (refer to Section 8.3).
• Connect the AC power supply wiring to the dedicated terminals described in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will burn out.
• Noise resistance may be lower when the L and N wires of an AC power supply are not wired correctly. Please wire using the correct polarity.
• Connect the DC power supply wiring to the dedicated terminals described in this manual. If an AC power supply is connected to a DC input/output terminal or DC power supply terminal, the PLC will burn out.
• Do not wire vacant terminals externally. Doing so may damage the product.
• When drilling screw holes or wiring, make sure cutting or wire debris does not enter the ventilation slits. Failure to do so may cause fire, equipment failures or malfunctions.
• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due to abnormal data written to the PLC under the influence of noise:
1) Do not bundle the power line or shield of the analog input/output cable together with or lay it close to the main
circuit, high-voltage line, or load line. Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line at least 100 mm (3.94") or more away from the main circuit, high-voltage line, or load line.
2) Ground the shield of the analog input/output cable at one point on the signal receiving side.
However, do not use common grounding with heavy electrical systems.
• Make sure to properly wire to the main unit in accordance with the following precautions. Failure to do so may cause electric shock, equipment failures, a short-circuit, wire breakage, malfunctions, or damage to the product.
- Make sure to properly wire to the main unit in accordance with the rated voltage, current, and frequency of each

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.

• Indication of 24 V DC service power supply
The AC power supply type has [0V] and [24V] terminals, whereas the DC power supply type shows [•] since the DC power supply type does not have the service power supply. [•] represents vacant terminals. Do not connect with vacant terminals. For external wiring, make sure to read the power supply wiring described later.
• Indication of input terminal
Both AC and DC power supply type have the same input terminals, however, the external input wiring differs from each other. For external wiring, make sure to read the input wiring described later.
• Indication of output terminals connected to common terminal
One common terminal covers 1 or 4 output points. The output numbers (Y) connected to a common terminal are enclosed with heavy partition lines. For transistor output (source) type, [COM] is [+V].

Avoid write during RUN to a circuit block including the following instruction during execution. If write during RUN is executed to such a circuit block, the PLC immediately stops pulse output.
• PLSV (FNC157) instruction [without acceleration/deceleration operation]
Avoid write during RUN to a circuit block including the following instructions during execution.
• PLSY (FNC 50), PWM (FNC 58) and/or PLSR (FNC 59) instructions
Avoid write during RUN to a circuit block including the following instructions during execution of communication. If write during RUN is executed to such a circuit block, the PLC may stop communication after that. If the PLC stops communication, set the PLC to the STOP mode once, and then set it to the RUN mode again.
• IVCK (FNC270), IVDR (FNC271), IVRD (FNC272), IVWR (FNC273), IVMC (FNC275) and ADPRW (FNC276) instructions
• Instructions for falling edge pulse When write during RUN is completed for a circuit including an instruction for falling edge pulse (LDF, ANDF, or ORF instruction), the instruction for falling edge pulse is not executed without regard to the ON/OFF status of the target device. When write during RUN is completed for a circuit including an instruction for falling edge pulse (PLF instruction), the instruction for falling edge pulse is not executed without regard to the ON/ OFF status of the device that is set as the operation condition. It is necessary to set to ON the target device or operation condition device once and then set it to OFF for executing the instruction for falling edge pulse.
Circuit blocks which require attention on operation after write during RUN
• Instructions for rising edge pulse When write during RUN is completed for a circuit including an instruction for rising edge pulse, the instruction for rising edge pulse is executed if a target device of the instruction for rising edge pulse or the operation condition device is ON. Target instructions for rising edge pulse: LDP, ANDP, ORP, and pulse operation type applied instructions (such as MOVP)

Others
*1 The PLS instruction is not executed.
Writing in RUN mode to circuit blocks including the following instructions results in the following operation
• MEP instruction (Conversion of operation result to leading edge pulse instruction) When completing Write during RUN to a circuit including the MEP instruction, the execution result of the MEP instruction turns ON (conducting state) if the operation result up to the MEP instruction is ON.
• MEF instruction (Conversion of operation result to trailing edge pulse instruction) When completing Write during RUN to a circuit including the MEF instruction, the execution result of the MEF instruction turns OFF (nonconducting state) regardless of the operation result (ON or OFF) up to the MEF instruction. When the operation result up to the MEF instruction is set to ON once and then set to OFF, the execution result of the MEF instruction turns ON (conducting state)
• When writing during RUN with GX Works2 the program is as follows. When the number of program steps is reduced by deletion of contacts, coils and applied instructions, the program capacity becomes smaller by as many as the reduced number of steps.
• Errors cannot be detected in write during RUN even in a circuit which causes errors. Errors are detected after the PLC is stopped once, and then run again.

7. Installation In Enclosure

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.

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.

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.

10.5.2 1-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.
Examples of program
1) For C246
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.

• 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.

10.6.2 Comparison 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.

10.7 Response Frequency and Overall Frequency
1. Response frequency and overall frequency
When any of the following functions/instructions is used, the overall frequency is restricted without regard to the operand of the instruction. Consider this restriction when examining the system or creating programs, and observe the specified overall frequency range.
• When two or more high-speed counters are used.
• When the HSCS instruction, HSCR instruction, HSZ instruction, PLSY instruction, PLSR instruction, DSZR
instruction, ZRN instruction, PLSV instruction, DRVI instruction or DRVA instruction is used.
