Status information such as the address of the positioning action currently being
executed is read from the Position Control Unit to the CPU Unit by the CPU Unit’s
Intelligent I/O Read instruction.
Note Commands and data cannot be transferred simultaneously by the Intelligent I/O
Write instruction.

the Position Control Unit.
