Efficiency questions when using Connect

Post by SMT_SOL » Mon Feb 10, 2020 7:42 am

alert DP I plan to use about 200000. Is it better to use dpQueryConnectSingle or alertConnect for efficiency?

Can you please describe your requirements in detail.
What do you want to achieve by connecting to the alerts?
How often are the alerts changed?
Do you really want to connect to all alerts?

Thank you for your kind reply

Use the alert on and off values.
I think there will be a change every 2-3 minutes.
I heard that alertconnect is fast when using alert DP.
(is that so?)
Even if the number of DPs used is large, I wonder if alertConnect is faster than Connectsingle.

What does "alert on and off values" mean in detail?
Do you want to get information for the value change?

I'm not sure what "alert DP" is in your project.
Can you describe it more accurate.
