(1)
Do not set two or more stations for the same station number, in the same
loop. If two or more stations are set for the same station number, these
stations may not operate properly. Make sure all stations are assigned
different station numbers.
(2) If remote terminal
or
I/O modules which have
two or more occupied
stations are used, set the station numbers skipping the numbers used
for occupied stations.
For example, if an A64RDC which has four
occupied stations is set for station 1 (as shown below) do not set other
remote I/O modules for stations
2,
3, and 4.
