Units B and C are units having 4 points dedicated to output. If a unit having 8 points dedicated to output
is connected as Unit C (station No. 3), latter four points will malfunction.
•
Station Nos. for input and station Nos. for output are already determined respectively. Even if the number
of occupied I/O points is not more than the specified number, an inappropriate unit cannot be connected.
For example, if a unit having eight points dedicated to input is connected to the station No. 6 or 7 which is
set for output, it will not function at all.
