Continuous

Burst Message is transmitted

continuously.

Window

In “Window” mode, the Trigger Value

must be a positive number and is the

symmetric window around the last

communicated value.

Rising

In “Rising” mode, the Burst Message

must be published when the source

value exceeds the threshold

established by the trigger value.

Falling

In “Falling” mode, the Burst Message

must be published when the source

value fall below the threshold

established by the trigger value.

On-change

In “On-change” mode, the Burst

Message must be published when the

source value on change established

by the trigger value.
