FC 300 Design Guide
In the following example, Read Parameter Description Elements is chosen on par. 0-01 Language,
and the requested element is index 1 Basic characteristics.
Basis characteristics (index 1):
The Basic characteristics command is split up in two parts representing basic behavior and data
type. The Basic characteristics return a 16-bit value to the master in PWE
The basic behavior indicates whether e.g. text is available or the parameter is an array
as single bit information in the high byte of PWE
The data type part indicates if a parameter is signed 16, unsigned 32 in the low byte of PWE
PWE high basic behavior:
Active parameter is only active when communicating through Profibus.
Array means that the parameter is an array.
If bit 13 is true, the parameter can only be reset, not written to.
If bit 12 is true, the parameter value is different from the factory setting.
Bit 11 indicates that text is available.
Bit 10 indicates that additional text is available. E.g. par. 0-01, Language, contains text
for index field 0, English, and for index field 1, German.
If bit 9 is true, the parameter value is read-only and cannot be changed.
If bit 8 is true, upper and lower limits of the parameter value are not relevant.
