7-1 Status Types
The CPU Unit receives two types of status from the Position Control Unit: 1) the
information that is transmitted with the I/O refresh, and 2) the detailed PCU in-
formation in 15 words (eight words for the NC113) that can be read by the CPU
Unit by means of the Intelligent I/O Read instruction. These two types are illus-
trated in the following diagram.
