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” | Normal mode | Fast processing ON | Improvement |
16,5 sec | 11,3 sec | 32 % | |
Read only “Application tag” 32 bytes | 7,62 sec | 6,40 sec | 17 % |
Write only “Application tag” 32 bytes | 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 % |
