Hello Everyone,

Could someone please explain the potential impact of a timer running every 5 seconds on gateway load?

I am currently using this timer to update the power table every 5 seconds.

How is your power table updated?

The timer itself has no impact, but what you do with it might.

Hi,

The output of the time value I bound with the button name and power table get updated using the property change script when the button name changes.

It works well, but I want to ensure that there will be any impact on running it unconditionally.

Where are you getting the data for the power table?

- If a query binding, then you should use the binding's polling option for unconditional updating. But also, you do need to make sure that the query can reliably deliver at that pace. If anything would be a problem, that would.

- Looks like a fine solution if the power table uses a computed dataset.

Keep in mind that Vision runs most such logic locally, not impacting the gateway at all. Queries **do** go through the gateway.

Hi,  
I have manually entered the specified tags into the power table. Subsequently, a button script will verify whether any alarms are active for those tags.
