3 Data Exchange with the CPU Unit
3-7 Device Variables for CJ-series Unit
(Configuration)
The CJ1W-PRT21 provides 8 consecutive DM words to indicate configuration and parameterisation
data received from the PROFIBUS-DP master unit. These words are not part of the cyclic refresh, but
the unit writes this information to the Host CPU when the data in the unit changes. At power-on, or at a
reset of the unit, all data will be set to 0. The DM words are in the area assigned to the Special I/O unit,
depending on the Machine No (see section 3-5-1 Data Flow).
