String Context-depend‐
ent
FlexString array of visible
characters with
preceeding cur‐
rent length
(UInt lenght)
(array of 8 bit)
Real 4
Data length is always given in Bytes!
Struct A structure is a sequence of further types. These types can be of a Basic‐
Type, Structs again or an Array.
Array An Array is a repetition of a type. The length of the array is defined with
each Array. The types can be of a BasicType, a Struct or an Array again (n-
dimensional).
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>
Description Value ASCII
Start of text <STX>
End of text <ETX>
Read sRN

If values are divided into two parts (e.g. measurement data), they are documented
according to LSB 0 (e.g. 00 07), output however is according to MSB (e.g. 07 00).
