Data Link Stop And Restart; Remote I/O Station Points Setting - Mitsubishi Electric MELSEC iQ-R Series User Manual

Precautions
■Device to be set in the refresh device setting
Whether remote output (RY) is refreshed or compulsorily cleared varies depending on the refresh device set for the remote
output (RY) in "Link Refresh Settings" under "Basic Settings" as described below:
• When Y is set, remote output (RY) is compulsorily cleared regardless of the module parameter.
• When a device other than Y, such as M and L, is selected, remote output (RY) is refreshed or compulsorily cleared
according to the setting.

Data link stop and restart

Data link can be stopped during debugging and other operations. Also, the stopped data link can be restarted.
If data link of a master station is stopped, data link is stopped in the entire system. ( Page 110 Stopping and restarting
data link)

Remote I/O station points setting

When the master station is in the remote net Ver.2 mode or remote device net Ver.2 mode, the number of refresh points with a
remote I/O station can be selected from 8 points, 16 points, and 32 points. Changing the number of points can save the areas
of the refresh device in a CPU module. (In modes other than the remote net Ver.2 mode and remote device net Ver.2 mode,
only 32 points per station can be selected.)
