10.3 Process data
Output/Input
buffer
The start addresses of the input and output data are assigned in the hardware configuration for
the host system. The BIS L-409-... uses 8 bytes of input and 8 bytes of output data, with assign
-
ment as described in the following. Subaddress 00hex corresponds to the respective start
address of the hardware configuration.
The BIS L-409-... provides two fields for sending commands and data between the BIS L-409…
and the host system:
Output buffer
Input buffer
These fields are embedded into the process data transmission via the IO-Link Master. As
described above, 8 bytes of process data are sent in each direction.
The map of this process data is described below:
