Appendix 3 Buffer Memory; List Of Buffer Memory Addresses - Mitsubishi Electric MELSEC iQ-R AnyWireASLINK User Manual

Appendix 3
Buffer memory is for data communications between the RJ51AW12AL and the CPU module or the RJ51AW12AL 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).
