Note: Every DPV1 read or write request must be acknowledged by the
PLC application program. Otherwise, the PROFIBUS master shuts down
communication for both channels, V0 (cyclic IO data) and V1 (non-cyclic
messages). This can cause unexpected lost of data between the master
and the ILX69-PBS.
Extended Status Information
Via the extended status area, the ILX69-PBS is ready to transfer 96 bytes of extended
status information to the controller application. The information transferred depends on the
parameter "ExtStaSelect" in the "Device Command Register". This can be controlled by the
application program.
If the controller application selects a specific extended status, it will be acknowledged by the
ILX69-PBS in the status region in "ExtStaSelect".
If the ILX69-PBS does not acknowledge this selection, the extended information is invalid.
The number of bytes within the extended status area depends on the selected status. The
number of valid bytes are shown in the status area in "ExtStaLen".
Extended Status 0: (Length 0 Byte):
No extended status information transferred.
