Diagnostics for the local XI/ON-BUS and the PROFIBUS-DP/
CANopen bus
For the local XI/ON bus or the PROFIBUS-DP bus: EXTENDEDINFO
contains general diagnostic data for the participants and the
diagnostic structure specified in the PROFIBUS-DP standard, with
six standard diagnostic bytes and the following manufacturer-
specific diagnostic data, as described on the device documentation
and the corresponding GSD file.
In the following description, the most important data have a grey
background.
EXTENDEDINFO[0] // for PROFIBUS-DP: Slave address
EXTENDEDINFO[1..4] // No significance
EXTENDEDINFO[5] // Length byte for the device diagnosis
EXTENDEDINFO[6&7] // No significance
EXTENDEDINFO[8..13] // 6 octets of DP standard diagnosis
according to the standard
EXTENDEDINFO[8] // Status_1
Bit 0: Device does not respond (no
valid IO-data)
Bit 1: Slave not ready
Bit 2: Configuration discrepancy
Bit 3: Extended diagnosis is
available
Bit 4: Unknown command
Bit 5: Invalid response
Bit 6: Parameterization incomplete
Bit 7: Parameterization from a
different master
EXTENDEDINFO[9] // Status_2
Bit 0: Ready for new start-up
sequence
Bit 1: No parameterization
Bit 2: „1“
Bit 3: Watchdog activated
Bit 4: FREEZE command active
Bit 5: SYNC command active
Bit 6: Reserved
Bit 7: Slave not incorporated in
project
EXTENDEDINFO[10] // No significance
EXTENDEDINFO[11] // With PROFIBUS-DP: master address
EXTENDEDINFO[12&13] // Own ID number
EXTENDEDINFO[14] // Length byte for the manufacturer-specific
data
EXTENDEDINFO[15..99] // Free for manufacturer-specific diagnosis.
2 bytes are available for local and remote
XI/ON modules, to hold general messages.
The messages are derived from the GSD file
for the local XI/ON and the remote XI/ON
Gateway. They are Bytes 15 and 16 of the
EXTENDEDINFO output. The next byte
(EXTENDEDINFO[17..max. 99]) contains
the error code for the modules with
diagnostic capability. This is performed in
the sequence of the modules. There is no
byte for modules without a diagnostic
capability.
EXTENDEDINFO[15] // Bit 0: Module diagnosis available
Bit 2: Parameterization incomplete
Bit 3: Configuration discrepancy
EXTENDEDINFO[16] // Bit 1: Field voltage error
(only for local XI/ON)
Bit 2: Module bus error
Bit 3: Master configuration error
Bit 4: No module detected
(only for local XI/ON)
Bit 5: Station configuration error
Bit 6: I/O assistant force mode
active
Bit 7: Module bus failure
EXTENDEDINFO[17...99] //One or more bytes for each module with
diagnostic capability
from
EXTENDEDINFO[17] //Diagnosis bytes for the modules with
diagnostic capability (

Example: power supply module
XN-BR-24VDC-D Bit 0: Module bus voltage warning
Bit 2: Field voltage missing
