Allocation Example
CM3-SP04EOAI
The CM3-SP04EOAI (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 CM3-SP04EOAI's position within the chassis.
To access the X memory registers for the CM3-SP04EOAI, the X value range is X2.0 ~ X2.F.
To access the Y memory registers for the CM3-SP04EOAI, the Y value range is Y2.0 ~ Y2.F.
CM3-SP04EOAV
The CM3-SP04EOAV (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 CM3-SP04EOAV's position within the chassis.
To access the X memory registers for the CM3-SP04EOAV, the X value range is X3.0 ~ X3.F.
To access the Y memory registers for the CM3-SP04EOAV, the Y value range is Y3.0 ~ Y3.F.
