  • Page 3: Safety Precautions

    SAFETY PRECAUTIONS (Read these precautions before using this product.) Before using products introduced in this handbook, please read relevant manuals and replacement handbooks carefully and pay full attention to safety to handle the product correctly. The precautions given in this handbook are concerned with products introduced in this handbook only. For the safety precautions of the programmable controller system, refer to the user's manual for the CPU module used.
  • Page 4 When the QJ51AW12D2 is used [Design Precautions] WARNING ● An AnyWire DB A20 system has no control function for ensuring safety. ● When connecting a peripheral with the CPU module or a personal computer with an intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the sequence program to ensure that the entire system will always operate safely.
  • Page 5 [Installation Precautions] WARNING ● Use the programmable controller in an environment that meets the general specifications in the user's manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.
  • Page 6 [Wiring Precautions] CAUTION ● Tighten the terminal block screws within the specified torque range. Undertightening can cause short circuit, fire, or malfunction. Overtightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction. ● Prevent foreign matter such as dust or wire chips from entering the module. Such foreign matter can cause a fire, failure, or malfunction.
  • Page 7 [Startup and Maintenance Precautions] WARNING ● Do not touch any terminal while power is on. Doing so will cause electric shock or malfunction. ● Shut off the external power supply (all phases) used in the system before cleaning the module or retightening the terminal screws or module fixing screws.
  • Page 8 When the LJ51AW12D2 is used [Design Precautions] WARNING ● An AnyWire DB A20 system has no control function for ensuring safety. ● When connecting a peripheral with the CPU module or a personal computer with an intelligent function module to modify data of a running programmable controller, configure an interlock circuit in the sequence program to ensure that the entire system will always operate safely.

  • Page 18: Chapter 1 Introduction

    INTRODUCTION INTRODUCTION 1.1 Replacement with AnyWire DB A20 The MELSEC-Q and L series do not have an MELSEC-I/OLINK master module. Therefore, the alternatives are the AnyWire DB A20 or the CC-Link/LT. Features for replacement are listed in the following table.

  • Page 19: Precautions For Replacement

    INTRODUCTION 1.2 Precautions for Replacement (1) Before replacing MELSEC-I/OLINK with AnyWire DB A20, refer to the manuals for each AnyWire DB A20 module, and check the functions, specifications, and how to use the modules. (2) After replacing MELSEC-I/OLINK with AnyWire DB A20, check the operation of the entire system before starting the actual operation.
