    FX2N-32ASI-M AS-interface Master Block Introduction 1. Applicable PLC 32ASI-M can be connected to FX , FX , FX , or FX Series PLCs. The I/O control points of both the 32ASI-M and PLC CPU must not exceed the host PLC’s maximum I/O point capacity.

  • Page 18: Maximum Controlled Slave Units

    FX2N-32ASI-M AS-interface Master Block Introduction 1. 1.3.2 Maximum Controlled Slave Units The 32ASI-M can connect up to 31 slaves. However, there is a limit to the maximum number of controllable slaves according to the PLC connected. 32ASI-M calculates the number of active slaves which can be operated, and sets a limit which cannot be exceeded.
  • Page 19 FX2N-32ASI-M AS-interface Master Block Introduction 1. 2) Active slaves fall into 2 limitation categories. a) Limitation 1 A slave which can operate is allocated the lowest available active slave address. A slave which exceeds the number of allowable active slaves cannot operate.
