On [Link I/O] page, you can display the status of safety I/O and system internal I/O.

  • Safety I/O: All safety I/Os are redundant (with two independent channels) to ensure no loss of safety features in the event of a single failure. See "5.2.1 I/O" for functional definitions and settings of safety I/O.
  • System internal I/O: Only the I/O status display of controller internal interface board is provided, and is not open to the user.
