If the response ID has the value 7 (request cannot be executed), then a fault
number
is saved in parameter value 2 (PWE2). The fault numbers are
documented in the following table.
Table 3-21
Fault numbers for the response ID "Request cannot be executed"
Fault No.
Significance
0
Inadmissible legal parameter number (PNU); if PNU is not available
1
Parameter value cannot be changed; if the parameter is a visualization parameter
2
Lower or upper limit exceeded
3 Erroneous
sub-index
4 No
array
5
Incorrect type of data
6
Setting not permitted (can only be reset)
7
Descriptive element cannot be changed; not possible
11
No operator control rights
12
Key word missing, device parameter: ‘access keyl’ and/or ‘special parameter access’ not
appropriately set
15
No text array available
17
Request cannot be executed due to operating states;
The frequency inverter state presently does not allow the request that was issued
101
Parameter number presently de-activated;
In the present frequency inverter state, the parameter has no function (e.g. closed-loop
control type)
102
Channel width too small: Only for short channels;
the parameterized length of the PKW area has been selected too large due to the
restrictions in the device. This fault message can only occur for the USS protocol on the
technology module T 100 if basic device parameters are accessed from this interface
103
Incorrect PKW number; only for G-SST 1/2 and SCB interface (USS).
The fault number is transferred in the following two cases:
¾
If the request involves all indices of an indexed parameter (request index equal to
255) or the complete parameter description is requested and a variable telegram
length was not parameterized.
¾
If, for the request issue, the parameterized number of PKW data in the telegram is
too low (e.g.: Changing from a double word and PKW number equal to 3 (words).
104
Parameter value not permissible;
This fault number is transferred if the parameter value – that is to be transferred – is not
assigned any function in the device or at the time of the change it is not able to be
transferred for internal reasons (although it lies within the limits).
105
The parameter is indexed
e.g. request: ‘PWE, change word’ for indexed parameters
106
Request not implemented
200
New minimum value
201
New maximum value
203
No BOP/AOP display,
Parameter cannot be displayed on the BOP or AOP.
204
The ‘BOP/AOP key word’ does not match the parameter access stage.
