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

Appendix 4
The buffer memory is used to exchange data between the FX5-ENET/IP and the CPU module or EtherNet/IP devices.
Buffer memory values are set to their defaults (initial values) when the system is powered off or the CPU module is reset.
