    When using Mitsubishi equipment, thoroughly read this manual and the associated manuals introduced in this manual. Also pay careful attention to safety and handle the module properly. These precautions apply only to Mitsubishi equipment. Refer to the CPU module user’s manual for a description of the PLC system safety precautions.

  • Page 4: Installation Precautions

    [INSTALLATION PRECAUTIONS] CAUTION Use the module in the environment given in the general specifications of the CPU module’s User’s Manual. Using the module outside the range of the general specifications may result in electric shock, fire or malfunctioning, or may damage or degrade the module. Insert the tabs at the bottom of the module into the mounting holes in the base unit before installing the module.

    FMA1/2 Layer 1 Physical layer The AJ71PB92D/A1SJ71PB92D has a physical layer, data link layer, DDLM, and user interface that conform to PROFIBUS-DP, and communicates data with the PLC CPU by using a buffer memory. The main application of PROFIBUS-DP is networks that execute high-speed communication at the level of sensors and actuators, and the AJ71PB92D/A1SJ71PB92D has been designed with this in mind: its functions are mainly related to data I/O with slave stations.

    RST reset instruction Point Pay attention to the increase of the scan time since it will take at least 3.3ms to process the FROM/TO instruction. It is recommended to perform the FROM/TO instruction for the AJ71PB92D/A1SJ71PB92D only once in each sequence scan.

    It is recommended to perform the FROM/TO instruction for the AJ71PB92D/A1SJ71PB92D only once in each sequence scan. (2) If the network configuration allows the power supplies to the A1SJ71PB92D and to the slave station to be on simultaneously, there may be cases in which the slave side is not completely started at the time the X1B turns on.

    APPENDIX MELSEC-A Appendix 2 Precautions for Replacing AJ71PB92 with A(1S)J71PB92D Pay attention to the following points when replacing the AJ71PB92 with the A(1S)J71PB92D. (1) The sequence programs and cable wiring prepared for the AJ71PB92 can be used for the A(1S)J71PB92D. (2) The parameters for the AJ71PB92 cannot be used for the A(1S)J71PB92D due to a file format difference.
