4-1 Overall Structure
The Programmable Controller controls the Position Control Unit (PCU) by
means of the data and memory areas shown below, employing data inputs and
outputs during I/O refreshing and at other times.
For the purposes of this example, the explanation is provided in terms of a
C200HW-NC413 PCU. For details regarding area allocation for NC113 and
NC213 PCUs, refer to
4-1-3 Area Allocation .

Note 1. The user can select by means of a common parameters setting whether
data is to be transferred to the PCU for use, or whether the axis parameters
saved at the PCU are to be used. (Refer to
4-2 Common Parameters Area .)
2. The data transfer area is required for transferring data to the PCU (except
when the SYSMAC-NCT Support Tool is used).
