3.2 I/O Signals to/from Programmable Controller CPU

3.2.1 I/O Signals in 4-Point Mode Setting

3 - 4
This section describes Input/Output (I/O) signals of the QJ61CL12 to/from the
programmable controller CPU.
Input signals (X) or output signals (Y) are allocated to the area of the Remote Input or
the Remote Output respectively. No I/O signals are required to activate the
QJ61CL12.
The assignment of I/O signals varies depending on the point mode setting.
In the following Table 3.3 to 3.5, "n" represents the start I/O number of the QJ61CL12.
[Example]
When the start I/O number of the QJ61CL12 is "X/Y30":
Xn0 to XnF X30 to X3F
Yn0 to YnF Y30 to Y3F
POINT
When the number of I/O points occupied is set exceeding the maximum number of
link points in the 4-point or 8-point mode, the excessive I/O points cannot be used.
Example) When setting as follows:
Point mode:4-point mode; No. of I/O point occupied:1024;
The QJ61CL12 occupies 1024 points of I/O for the programmable
controller CPU, however, available link points are 256 (Max. link points
for 4-point mode are 256) and the remaining points of 768 are not
possible to be used.
List of the I/O signals in the 4-point mode setting is shown in Table 3.4.
