Remote Net Additional Mode - Mitsubishi Electric MELSEC-Q Series User Manual

3.6.5

Remote net additional mode

This mode is selected when a Ver.2-compatible slave station is added to an existing Ver.1 system and cyclic points are
expanded. Unlike the remote net Ver.2 mode, RX, RY, RWr, and RWw in a Ver.1-compatible slave station are stored
into buffer memory for the Ver.1 (same buffer memory addresses); therefore, a program in the remote net Ver.1 mode
can be used.
