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.
