Parameter channel

Structure of the parameter channel
The parameter channel consists of four words. The 1st and 2nd words transfer the
parameter number, index and the type of task (read or write). The 3rd and 4th words contain
the parameter content. The parameter contents can be 16-bit values (such as baud rate) or
32-bit values (e.g. CO parameters).
Bit 11 in the 1st word is reserved and is always assigned 0.
You can find application examples relating to the parameter channel at the end of this
section.
AK: Request and response IDs
Bits 12 ... 15 of the 1st The parameter channel words contain the request and response
identifier AK.
