Dedicated I/O type unit mode
When remote I/O units dedicated to input or output (having eight or four input or output points) are used, the
dedicated I/O type unit mode can be selected. (When a mixed I/O type remote I/O unit having both input and
output points in one unit or a remote I/O unit having 16 points in one unit is used, this mode cannot be
selected.)
1 ) When the I/O occupation setting switch MOD2 is set to OFF, I/O No. assignment in the dedicated I/O type
unit mode is selected.
2 ) By turning on/off the switches MOD0 and MOD1, determine the number of I/O points occupied by the
remote I/O system.
3 ) Assign a station No. and I/O Nos. to each remote I/O unit to be used. (Refer to the assignment table
offered as attachment.)
X (input)
Y (output)
0
In this mode, each station No. is already assigned to input or output.
Eight points (for two stations) are treated as one unit, and input and output are set alternately from the station
Nos. 0 and 1.
* If a remote unit dedicated to output is connected to a station No. set for input, malfunction will occur. If a
remote unit dedicated to input is connected to a station No. set for output, malfunction will occur. (If a mixed
I/O type unit or a unit having 16 points is connected, malfunction will occur also.)
