Appendix 3 Buffer Memory
When using the RJ71EN71 (network type: Q-compatible Ethernet)
With the Q-compatible Ethernet, the same buffer memory addresses as the MELSEC-Q series Ethernet interface module can
be used, excluding some addresses.
■Buffer memory addresses usable only with RJ71EN71
The following table lists the buffer memory addresses that can be used only with RJ71EN71.
■Buffer memory addresses differing from MELSEC-Q series Ethernet interface modules
The following table lists the buffer memory addresses having specifications that differ from the ones of the MELSEC-Q series
Ethernet interface module.
