Allocation Example

CM3-SP02ERS

The CM3-SP02ERS 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-SP02ERS's position within the chassis.

To access the X memory registers for this CM3-SP02ERS example, the X value range is X2.0 ~ X2.F.
To access the Y memory registers for this CM3-SP02ERS example, the Y value range is Y2.0 ~ Y2.F.

CM3-SP02ERR

The CM3-SP02ERR 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-SP02ERR's position within the chassis.

To access the X memory registers for this CM3-SP02ERR example, the X value range is X2.0 ~ X2.F.
To access the Y memory registers for this CM3-SP02ERR example, the Y value range is Y2.0 ~ Y2.F.
