DCO keep losing assocation with sensors from DCE ?

[DCIM_Support]

Currently running DCE V7.5.0 and DCO 8.2.2, I have recently completed device association of hundreds of current and power sensors from DCE and DCO. DCO operation confirmed association are working by displaying Peak current and peak power reading within the PDU branch circuits. However, a couple weeks later, these reading in DCO are randomly disappearing and DCO PDU property indicated the association were lost.

Can anyone advise under what condition DCO will claim the association is lost even though DCE showed the sensor reading are all perfect within the duration?

Hi Jimmy,

That may/can happen when the associated device (DCE device) gets a new ID in scenarios like device being re-added/rediscovered in DCE, and/or if the DCE server "moved" to another host (due to hardware change or other reasons).

Kind regards

Thanks for your prompt response. This is defintely not the case for me, there is no change of device ID in DCE. the DEVICE in DCE is a PDU which has up to 48 current and power sensors within the device. But DCO only lost some current reading and all power reading is working fine. If there is is no change of DCE device ID, should this be happened?
