Packed process data
Packed input process data
Input register range: 0x0000 to 0x01FF
Access to all 512 registers is always possible
regardless of the I/O structure. Unused regis-
ters respond with “0”.
Packed output process data
Output register range: 0x0800 to 0x09FF
Access to all 512 registers is always possible
regardless of the I/O structure. Unused regis-
ters send “0” during a read access, write ac-
cesses 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 u-remote station.
The start address(es) of each module’s process
data are listet in register 0x2B00 – 0x2B7F
(s.section „Module offsets of process data“ on
page71).
Process data is mapped according to
the modules are arranged. To avoid larger
gaps in the process data, the different modules
should be arranged in an optimal manner.
