Appendix 4 Buffer Memory; List Of Buffer Memory Addresses - Mitsubishi Electric MELSEC iQ-F FX55-ASL-M User Manual

Appendix 4
Buffer memory is for data communications between the FX5-ASL-M and the CPU module or the FX5-ASL-M and slave
modules.
When the CPU module is reset or the system is powered off and on, the data in the buffer memory are set back to the default
(initial values).
