To be able to access the trend information while the device is no longer being polled we put the element to a paused state.
When an element is paused will it drop all the connections between the DMA and the device or will it only pause the communication?
The main difference between a stopped and a paused element is that in the case of a stopped element, the virtual IP address is destroyed. This means that in a paused state users can still access the element and all associated resources, while this is not possible when the element is stopped.
Your assumption that the communication between DMA and device will stop in both cases is correct.
