3.4.4 Clearing the overlapping sending SA
If the scan block is sent from multiple nodes redundantly, it is an
overlapping sending state. In the LAN transmission map screen, the
background color of the clock changes to red to indicate the occurrence of
the overlapping state. At the same time, two numbers are displayed in
the block, indicating the node number where the overlapping state exists.
To clear the overlapping state, reset the scan sending block, and
download it to the node with the overlapping state.
After clearing the overlapping state, check that the operation is normal.
The overlapping sending map retains the state once the overlapping
sending state is detected. Therefore, to confirm the state recovery, clear
the overlapping sending SA (station address).
