8-13
2) Do not skip station numbers
The skipped station numbers are treated as "data link faulty stations" (which can be
checked in the link special register SW0080 or the buffer memory address 680
H
). However,
by setting such stations as reserved they are not treated as data link faulty stations.
Setting example 1: When one station number is skipped
3) Duplicate station numbers are not allowed.
If there are duplicate numbers, a loading status error occurs. (The error code is stored in
SW0069.)
Setting example: When one station number is duplicated
