Flex Array
A FlexArray is a repetition of a type with a variable length. The maximum
length of the array is defined with each FlexArray. The current length of the
FlexArray is transferred as a UInt preceeding the Array itself. The types can
be of a BasicType, a Struct or an Array again (n- dimensional).
SOPAS communication is a index based communication and can be identified with
telegram beginning of: sRI, sWI, sMI, sAI, sEI, sSI. Since the parallel usage of one port
might be confusing, the usage of separate ports is adviced.
Every response telegram starts with a separat framed string:
<STX>sSI 2 1<ETX><STX>"Answer"<ETX>

according to LSB 0 (e.g. 00 07), output however is according to MSB (e.g. 07 00).
