AC800 M controller Time sync with 800xA and compact solution
We have 10 controller in 800xA system PM866 and PM864.
Out of that 2 are CNCP master and rest of the 8 are synching without any issue.
We have another 4 controller in compact solution which is also configured same as other 8 controller to sync time. But these 4 controller are getting warning 'No Time Sync'.
These 4 controllers are in the network and they are communicating with all other controller in IAC.
On opening Tools/Maintenance/clock Sync Status from the compact controller I can see the time difference is 0ms with first Master and few micro seconds with second master.
But I cannot see or I cannot add theses 4 controller in time sync under tools /Maintenance/timesync.
Attached is the screenshot from 800xA.
IP ends with 203,204,205,206 are the culprits.
Any idea of these behaviour ?
