Allocation Example
IO-SA0004C
The IO-SA0004C (current) is allocated one WORD of X (Xn.0 ~ Xn.F) and one WORD of Y (Yn.0 ~ Yn.F).
n is a number representing the IO-SA0004C‘s position within the chassis.

To access the X memory registers for the IO-SA0004C, the X value range is X4.0 ~ X4.F.
To access the Y memory registers for the IO-SA0004C, the Y value range is Y4.0 ~ Y4.F.
IO-SA0004V
The IO-SA0004V (voltage) is allocated one WORD of X (Xn.0 ~ Xn.F) and one WORD of Y (Yn.0 ~ Yn.F).
n is a number representing the IO-SA0004V‘s position within the chassis.

To access the X memory registers for the IO-SA0004V, the X value range is X5.0 ~ X5.F.
To access the Y memory registers for the IO-SA0004V, the Y value range is Y5.0 ~ Y5.F.
