Device-related diagnostic data, 9th. byte
Table 15
Description of the individual bits (texts in quotation marks are
diagnostic messages from the device database):-
Device-related diagnostic data, 10th. and 11th. byte
for later extensions, (not yet implemented)
Device-related diagnostic data, 12th. to 16th. byte
This diagnostic data must be interpreted depending on the
information from the 8th. and 9th. byte. Only if these bytes are
unequal to 0x00, evaluable information is given here. -These bytes
are not needed for all diagnostic bits
"I-block of slave too small"
Byte 12Always set to 0x00
Byte 13, 14
Necessary length of input data block in bytes,
calculated from the configuration data. The
maximum permissible length is specified in the
device database (GSD file). -
Byte 15, 16
Necessary length of output data block in bytes,
calculated from the configuration data. In this
diagnostic data this value is smaller than the value
specified in the device database (GSD file).
"O-data block of slave too small"
Byte 12Always set to 0x00
Byte 13, 14Necessary length of input data block in bytes,
calculated from the configuration data. In this
diagnostic data this value is smaller than the value
specified in the device database (GSD file).
Byte 15, 16Necessary length of output data block in bytes,
calculated from the configuration data. The
maximum permissible length is specified in the
device database (GSD file). -
"PRM conf greater than CFG data"
Byte 12always set to 0x00
Byte 13, 14Necessary length of input data block in bytes,
calculated from the configuration data.
Byte 15, 16Necessary length of output data block in bytes,
calculated from the configuration data.
"PRM data: Obj-Id faulty“
Byte 12Number of faulty bytes in the "User _Prm_Data". Counter
starts with 1 and counts the bytes.
Byte 13, 14Faulty byte which is unknown to the connected slave.
Byte 15, 16Always set to 0x00.
"Unknown module in CFG"
Byte 12Position of faulty module in configuration data, counted
from the start of the configuration data.-- Counter
starts with 1 and counts the bytes.
Byte 13, 14The bytes specified in the configuration data for the
first faulty module.
Byte 15, 16
Always set to 0x00.
"Acyclic: Data cannot be evaluated“
Byte 12Service index with a faulty variable index. -
Byte 13, 14Number of the acyclic service module in which the
error was found. --Counted from 1 to 4.
Byte 15, 16Faulty variable index which is unknown to the
connected slave. -
"Acyclic: Unknown service"
Byte 12Faulty service index for an acyclic service.
Byte 13, 14Number of the acyclic service module in which the
error was found. - -Count from 1 to 4.
Byte 15, 16

"No communication with
controller”
The PROFIBUS-DP
module cannot establish
a communication with
the basic device. --
A hardware defect of the
device or module may be
the reason. Check the
basic device with
another module and the
module with another
basic device. ----
