A.1.1.3
Parameter value (PWE)
The number of PWEs can vary according to the configuration. The number can be
configured in parameter p2023 (Number of PKWs).
A PKW channel width of at least 3 words is required to transfer 16-bit values. This means
that PWE1 is provided.
If 32-bit values are transferred, the PKW channel has to be expanded to 4 words.
Correspondingly, PWE1 and PWE2 are then available.
Note
Variable PKW proportions and variable telegram lengths are not currently supported. This
means that description texts, texts and complete arrays cannot be transferred.
Note
If a 16-bit value is transferred in a 32-bit channel in the PWE2, then the content of PWE1 is
0.
