8.9.6.4 SmartWire-DT write request – Write job
Only individual parameter writing is supported (i.e., array and multiple
parameter writing is not supported). The maximum parameter request frame
length is set at 16 bytes. The maximum length of a writable parameter is one
double word. All kinds of objects can be transmitted in the parameter
channel – these objects are identified by what is referred to as a PNU
(parameter number) and a subindex. The write request includes a declaration
that specifies that the job is a write job.
The valid formats (byte 10) for the DS7-SWD soft starter from PROFIdrive
profile are marked in the following table:
