Appendix 3 Buffer Memory; List Of Buffer Memory Addresses - Mitsubishi Electric FX5-DP-M User Manual

Appendix 3
The FX5-DP-M exchanges data with the CPU module through the buffer memory. Data in the buffer memory are reset to the
defaults (initial values) when the CPU module is turned off or reset.
