4.4.5 Packed Process Data

Packed input process data
Input register range: 0x0000 to 0x01FF
Note: Access to all 512 registers is always possible regardless of the I/O structure. Unused registers
respond with "0".
Packed output process data
Output register range: 0x0800 to 0x09FF
Note: Access to all 512 registers is always possible regardless of the I/O structure. Unused registers
send "0" during a read access, write accesses are ignored.
Structure of packed process data
The byte granularly packed process data contains all input data (register range 0x0000 to 0x01FF)
and output data (register range 0x0800 to 0x09FF) of the RSTi-EP station.
Note: The start address(es) of each module's process data are listed in register 0x2B00 – 0x2B7F
(refer to the section 0x2B00 – 0x2B7F Module offsets of process data).
Note: Process data is mapped according to how the modules are arranged. To avoid larger gaps in
the process data, the different modules should be arranged in an optimal manner.
