1) When access is made with request identifiers for simple variables to parameters which are
implemented as arrays, the subindex is ignored or set to 0. This means that it is always the
first element of an array which is addressed.
2) Requests with non-supported request numbers (ReqID) will be answered with response
identifier 7 and fault number 22.
