Allocation Example
The CM3-SP04EAO 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 CM3-SP04EAO's position within the chassis.
To access the X memory registers for this CM3-SP04EAO example, the X value range is X2.0 ~ X2.F.
To access the Y memory registers for this CM3-SP04EAO example, the Y value range is Y2.0 ~ Y2.F.
