Table 4-15 Error IDs for the ”DP slave POSMO A”
Error identifier Error cause
0 Illegal parameter number (the parameter does not exist)
1 Parameter value cannot be changed (Parameter can only be read or is write
protected)
2 Upper or lower value limit exceeded
3 Incorrect sub–index
4 No array (parameter does not have any sub–parameter)
5 Incorrect data type
9 Description data not available
17 Request cannot be executed due to operating status
18 Other error
The data type, to which the parameter is assigned, must be written into
the parameter values using the PKW mechanism.
The following apply for the format names (acc. to the recommended
PROFIBUS guideline):

Description
C4 4 Fixed–point value, 32 bit with 4 decimal places (value = number/10 000)
Example:
P11 = 75 000 ––> 7.5 mm
I4 4 32–bit integer number (32–bit integer)
I2 2 16–bit integer number (16–bit integer)
T4 4 32–bit time constant (as for unsigned 32–bit integer)
Time as a multiple of the sampling time of 10 ms
T2 2 16–bit time constant (as for unsigned 16–bit integer)
Time is entered as a multiple of the sampling time
Speed control = 1 ms, position control = 10 ms
