In CET IED online diagnostics showing as suspended

Hi,

In CET tool under my project I have added 1 IED and imported the CID file which was taken from IED using IED Scout tool.I have manually configured the Clients to the RCBs.And did the update and Relod the configuration.After this I did right click on IED and checked online diagnostics.Online diagnostics showing Connection Status as suspended and Detaled Status as Not Connected.The IED I am able to ping.

I am attaching the SCD file which is exported from CET and the online dignostics screen shot for your reference

Please let me know what will be the probable reasons for "Connetion Status= suspended'

CET version is 6.0.1

And the CET project is having the 23 IEDs in addition to this EDG IED which is not communicating.

Project Deatils:

ADCO Mender SCMS Project

Abu Dhabi(UAE)

800XA version is : 6.0.1

Thanks & Regards
