4-1-3 Data Exchange Using the Words Allocated in DM Area
The data exchanged using the words allocated in DM Area consists of two types
of data.
1, 2, 3... 1. At startup or Unit restart, the Customizable Counter Unit’s initial settings
(e.g., the startup operating mode) are transferred from the CPU Unit’s DM
Area words m to m+9.
2. General-purpose data is exchanged cyclically between the DM Area words
m+10 to m+99 and the user-set words (e.g., in the DM Area or CIO Area) in
the Customizable Counter Unit.
