Safety Precautions (Read these precautions before using.)

(1)

Before installation, operation, maintenance or inspection of this product, thoroughly read through and understand this manual and the associated manuals. Also, take care to handle the module properly and safely. This manual classifies the safety precautions into two categories: WARNING and .

WARNING Indicates that incorrect handling may cause hazardous conditions, resulting in death or severe injury.

Indicates that incorrect handling may cause hazardous conditions, resulting in medium or slight personal injury or physical damage.

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

WARNING Make sure to include the following safety circuits outside the PLC to ensure safe system operation even during

external power supply problems or PLC failure. Otherwise, malfunctions may cause serious accidents. 1) Above all, the following components should be included: 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) Note that when an error occurs in a relay, triac 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 100mm (3.94) or more away from the main circuit or power line. Noise may cause malfunctions.

Ground the shield wire or shield of the shielded cable at one point on the PLC. However, do not ground them at the same point as the high-voltage lines. Noise may cause malfunctions.

Install module so that excessive force will not be applied to the terminal blocks. Failure to do so may result in wire damage/breakage or PLC failure.

1. Introduction

1. Introduction

1.1 Outline Thank you very much for your continued use of Mitsubishi PLCs. It may be time to renew your PLCs due to aging or deterioration over years of use, discontinued production of products, or termination of service or repair term. This manual describes the procedure of replacing your FX (FX1N, FX1NC) series PLCs with FX3 series PLCs.

1.1.1 Replacement models

To replace FX (FX1N, FX1NC) series PLCs, a system configuration composed of FX3 series models is recommended. Recommended replacement models introduced in this manual are general representative models selected based on the number of inputs and outputs, program capacity, and shapes of input and output terminals (terminal blocks, connectors, etc.). Depending on actual usage, models other than the recommended ones may be more suitable.

1.1.2 Necessity of renewal

(1) Our products are composed of very reliable parts including a great number of electronic components. When all components function normally, optimal functions and performance of the product will be realized. However, some parts (electrolytic capacitors, relays, switches and others) have a limited service life. The length of the service life varies depending on the part, and if used beyond the service life, optimal operation can not be expected and troubles or failures may occur. Generally, the deterioration of electronic components depends on the operating environment, and premature deterioration may occur if used in hot environments, overloaded conditions, or if incorrectly installed or connected. Deterioration of parts due to aging or environment may shorten the service life of the product, and periodic renewal becomes necessary.

(2) Systematic and planned preventive maintenance. Failures are often caused by parts deteriorated due to aging or operating environment. In equipment whose production is finished, it may take considerable time for recovery from failures. It is necessary to secure spare parts and perform systematic and planned maintenance and renewal.

2. Replacement of FX1N series

2. Replacement of FX1N series

2.1 Outline This chapter describes the procedure to replace the FX1N series with its successor, the FX3G series. Replacement is recommended.

2.1.1 Cautions

(1) "Recommended replacement models" lists the most fitting FX3 series product based on specification comparison. Depending on the operation environment or the system configuration (connection of expansion equipment), or when the number of inputs and outputs in use is smaller, other products may be more appropriate than the recommended replacement model.

(2) Recommended replacement models for extension blocks, extension units, special function modules, expansion boards, and batteries are selected based on compatibility with current FX3 series main units.

(3) Pay close attention to notes marked as "Special remarks". For attributes such as external dimensions, there can be slight differences between the recommended replacement model and existing product. Before performing replacement, be sure to review other relevant details such as dimensions, and power supply requirements.

(4) For instances where there is no recommended replacement model, a message stating "No recommended replacement model" will be shown. In this case, a FX3 series system may still be able to provide equivalent operation. Evaluate the requirements of the application and use a FX3 series system configuration for replacement.
