Mitsubishi Electric MELSEC-A/QnA Series - Buffer Memory Address Comparison

2 ANALOG INPUT MODULE REPLACEMENT
2 - 25
2.4.4 Buffer memory address comparison
Sequence program change is required as the assignment of buffer memory differs.
For details of the buffer memory or sequence program, refer to the Channel Isolated Analog-Digital
Converter Module, Channel Isolated Analog-Digital Converter Module (With Signal Conditioning
Function) User's Manual.
