Whether or not to detect a failed node is set in this area.
The setting determines whether or not the off status in Node Communication
Status (address: 01BC
H
to 01BF
H
) is reflected to Slave Down Signal (X04).
• When the corresponding bit is on: Slave Down Signal (X04) is not set to on even
if the slave node went down.
• When the corresponding bit is off: Slave Down Signal (X04) is set to on if the
slave node went down.

For a node that is set as a reserved node with a master function parameter, turn on
the corresponding bit of Failed Node Detection Setting. If it remains off, it is
recognized as a failed node even if it is just a reserved node.
