Please note: Data are stored in the "Big-Endian"
format! This means that the byte with the highest
value bits is initially stored at the memory location
with the lowest address:
Example using "number of strokes"- see "data from
pump"
The pump stroke rate is stored as Integer32 type at the offset
addresses +17 to +20. Bytes are stored in this sequence:
Name Type Off. Byte Bits
Number of
strokes
Integer32 17 0 24 ... 31
18 1 16 ... 23
19 2 8 … 15
20 3 0 … 7
Communication takes place in cyclic data traffic.
The cyclic data frame comprises:
