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

Appendix 3
The buffer memory is used to exchange data between the RJ71EIP91 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.
