Problem:
How can I improve performance during reads? |
Solution:
Performance may be poor if you are reading many "scattered" items in your OPC Client. For example,
4:1, 4:2, 4:4, 4:8, 4:26, 4:30, 4:42, etc.
There is a gap between each of them.
If you put them into groups by "filling in the gaps", you can get better performance, e.g.:
4:1 4:2 4:3 4:4 4:5 4:6 4:7 4:8
4:26 4:27 4:28 4:29 4:30
4:42
The server will be able to send three read commands to the Modbus device instead of six. |
