What causes Unity error "Due to alignment constraint, you have to decrease or increase topological address index of 1"?

In Unity Pro/Control Expert, 32 bit datatypes must be mapped to an even address boundary when using the M340 & M580 PLCs.
For example, variables of REAL or DINT datatypes must be mapped to %MW2, not %MW1.
