This bit is set by the master when the master receives an invalid answer from
the slave. The physical contact to the slave works, but the logical does not or
was interrupted. This may occur if a PROFIBUS-FMS slave is connected to
the DP-master. The slave does not understand the DP-Telegrams and rejects
them. It is handled as "Invalid_Slave_Response".
 Not_Supported
This bit is set by the slave when a function should be performed that is not
supported. Newer releases of slave stations normally support the Sync and
Freeze Mode for I/O data. This is set in the GSD file, read by PROLINX
SyCon, and transferred to the slave in the parameter telegram. If
"Not_Supported" is reported, the GSD file declares at least one of these
commands as supported, but the slave does not. Ask the manufacturer of the
slave device for another GSD file or ask if the slave reports "Not_Supported"
on other wrong parameter data.
 Extended_Diag
This bit is set by the slave if optional extended diagnostic data are a
containment of the slave diagnostic field. A slave station normally uses
extended diagnostic data if module-specific diagnostic information, for
example, exceeded analog values or low power should be reported to the
master. Click the Extended Diagnostic button to view a Hex-dump of the
reported values.
 Configuration_Fault
During the PROFIBUS-DP startup procedure, the slave compares its internal
I/O configuration with the one configured in the master. If the slave detects
differences, it reports the "Cfg_Fault" error. This indicates that the master has
a different I/O module constellation for this slave configured, than the slave
device physically holds down. First compare visually all configured I/O
modules in the configuration data of PROLINX SyCon for this slave with its
real physical constellation. Note that the order of the module is important and
should also be compared. Some slaves need virtual I/O modules to be
configured first or empty slot modules to get an even number of modules to
run. This slave specific I/O module behavior can normally be read out in the
slave documentation. Last help to get the slave module constellation is to
read out its constellation by a PROFIBUS-DP command Compare
Configuration. Click on this button in the diagnostic field and get a Hex-
Dump of the real slave configuration data and the configured one (Real
Configuration and PROLINX SyCon Configuration). Note that the DP-
configuration data is coded in bit defined byte arrays to hold the I/O
information very compressed. The DP configuration is coded in a very
compact form. The code for the modules is shown in the slave
configuration.
 Station_Not_Ready
When or at which event the slave sets this bit is not defined in the norm
specification. The meaning "Not_Ready" can be seen as not ready to perform
the I/O data exchange. This may indicate several slave specific reasons.
Usually the bit is set in combination with one of the other fault bits.
 Station_Non_Existent
