Meaning
00 hex
Illegal parameter number (access to a parameter that does not exist)
01 hex
Parameter value cannot be changed (change request for a parameter value that cannot be changed)
02 hex
Lower or upper value limit exceeded (change request with a value outside the value limits)
03 hex
Incorrect subindex (access to a parameter index that does not exist)
04 hex
No array (access with a subindex to non-indexed parameters)
05 hex
Incorrect data type (change request with a value that does not match the data type of the parameter)
06 hex
Setting not permitted, only resetting
(change request with a value not equal to 0 without permission)
07 hex
Descriptive element cannot be changed (change request to a descriptive element that cannot be changed)
09 hex
Description data not available
(access to a description that does not exist, parameter value is available)
0B hex
No master control (change request but with no master control)
0F hex
Text array does not exist
(although the parameter value is available, the request is made to a text array that
does not exist)
11 hex
Request cannot be executed due to the operating state
(access is not possible for temporary reasons that are
not specified)
14 hex
Inadmissible value
(change request with a value that is within the limits but which is illegal for other permanent
reasons, i.e. a parameter with defined individual values)
15 hex
Response too long (the length of the actual response exceeds the maximum transfer length)
16 hex
Illegal parameter address
(illegal or unsupported value for attribute, number of elements, parameter number,
subindex or a combination of these)
17 hex
Illegal format (change request for an illegal or unsupported format)
