3 SPECIFICATION
MELSEC-QnA
(f) Error invalid station specification
This is set so that the remote/local station that can no longer perform data
link due to power off, etc. will not be treated as a "data-link faulty station" on
the master station and the local station.
Be careful, however, for errors will not be detected.
1
When the same station number is specified as a reserved station, the
reserved station specification has the priority.
2
Turn on the bit corresponding to the station number of the invalid station.
However, for remote/local stations that occupy more than 2 stations, turn
on the only bit for the station numbers set by the module's station
number setting switch.
1 to 64 in the table below indicate the station numbers.
