ISDU fast processing

iqInterface FW Version 1.2.3.20 is required

This mode decreases a request time for ISDU Read/Write.

The difference with and without fast processing mode

Mode	Device: COM3 Min. cycle time: 1 ms On Request length: 2 bytes Process Data Length: 4 bytes
Sequence Read/Write “Application tag” 32 bytes (100 times)	Normal mode	Fast processing ON	Improvement
Sequence Read/Write “Application tag” 32 bytes (100 times)	16,5 sec	11,3 sec	32 %
Read only “Application tag” 32 bytes (100 times)	7,62 sec	6,40 sec	17 %
Write only “Application tag” 32 bytes (100 times)	8,18 sec	4,27 sec	48 %
Sequence Read/Write 1 byte integer (50 times)	4,83 sec	2,40 sec	50,32 %
Read only 1 byte integer (50 times)	4,80 sec	3,20 sec	33,33 %
Write only 1 byte integer (50 times)	4,82 sec	1,60 sec	66,77 %
