10 Diagnostic status register
Information on the operating and error states of the Axi-
olineF local bus is stored in the diagnostic status register of
the bus coupler. A state of the AxiolineF local bus is as-
signed to each bit in the diagnostic status register.
The states in the error bits (F_PW_BIT, F_PF_BIT,
F_BUS_BIT, F_CTRL_BIT) are described in greater detail
using the two diagnostic parameter registers. For informa-
tion on this, please refer to the AXLFSYSDIAG user man-
ual.
Structure of the diagnostic status register
The diagnostic status register can be read using asynchro-
nous services (index 2210
hex
, 8720
hex
).
Example in PCWorx: sending a read service
The RDREC function block is available for sending read ser-
vices.

Bit Designation Meaning
00 F_PW_BIT I/O warning At least one device indicates an I/O warning.
01 F_PF_BIT Peripheral fault At least one device indicates a peripheral fault.
02 F_BUS_BIT Bus error A bus error has occurred.
03 - Reserved
04 - Reserved
05 F_RUN_BIT Run Data cycles are being exchanged, the output data is en-
abled.
06 F_ACTIVE_BIT Active Configuration is active, PDI to the devices is possible, data
exchange with invalid/non-enabled process data.
07 F_READY_BIT Ready The local bus master is ready for operation, no data ex-
change over the bus.
08 F_BD_BIT Bus different A device which does not belong to the current configuration
has been detected at the last interface.
09 F_BASP_BIT SYS_FAIL The controller is in the STOP state or no application program
has been loaded. The output data is blocked (substitute
value behavior is active).
10 F_FORCE_BIT Force Mode Force mode (startup tool/I/O check is active).
11 F_SYNC_BIT Synchronization Synchronization between higher-level system and local bus
master has failed.
12 F_PARA_BIT Parameter error Startup parameters missing for at least one device.
