This function is for library's internal use only.
Supported platforms: CODESYS 2.3, CODESYS 3.5
This function generates a hash code to given event.
The hash code is used for fast comparison of events' type and status. Sorting in list view is done with the code.
The 16-bit hash code includes log view sorting order:
|
Bit 7 (2#x000 0000) |
Selection between type and mask |
|
1 |
Use bits 0..2 as mask bits (m) and bits 4..6 as order (r), for example 2#1rrr 0mmm |
|
0 |
Use bits 0..2 as type definitions (t), for example 2#0000 0ttt |
Direction
|
Bit 3 (2#0000 x000) |
Direction |
|
1 |
Direction is descending |
|
0 |
Direction is ascending |
Type definition bits (t)
|
Bits 0..2 (2#0000 0ttt) |
