Example:
Index:
[0] = USS on RS485
[1] = USS on RS232
Notice: USS protocol consists of PZD and PKW which can be changed by the user via parameters P2012 and P2013
respectively.
Parameter P2013 determines the number of PKW-words in a USS-telegram.
Setting P2013 to 3 or 4 determines the length of the PKW words (3 = three words and 4 = four words).
When P2013 set to 127 automatically adjusts the length of the PKW words are required.
If a fixed PKW length is selected only one parameter value can be transferred.
In the case of indexed parameter, you must use the variable PKW length if you wish to have the values of all indices
transferred in a single telegram.
In selecting the fixed PKW length, it is important to ensure the value in question can be transferred using this PKW
length.
P2013 = 3, fixes PKW length, but does not allow access to many parameter values.
A parameter fault is generated when an out-of-range value is used, the value will not be accepted but the inverter
state will not be affected.
Useful for applications where parameters are not changed, but MM3s are also used.
Broadcast mode is not possible with this setting.
P2013 = 4, fixes PKW length.
Allows access to all parameters, but indexed parameters can only be read one index at a time.
Word order for single word values are different to setting 3 or 127, see example below.
P2013 = 127, most useful setting.
PKW reply length varies depending on the amount of information needed.
Can read fault information and all indices of a parameter with a single telegram with this setting.
Example:
Set P0700 to value 5 (0700 = 2BC (hex))
