IT Asset Switch/GPS clock does not remain connected to OPC source
i have some issues with the switches it asset and i need your help: when i added the switches to the IT asset structure , after configuration i get this erros on system status viewer. 
The old switches connect to the OPc when i do subscribe data and get good data quality. The data remains the same
On new switches when i do subscribe i get good quality data in the beginning..but after 10 seconds the data goes bad. To add a news switch i add the Object Cisco 24/24 port switch to the IT server / switches . Then i add the IP on IT general property . Then i do Populate from IT device manager to populate the IT control connection properties. After that i add the Graphic element for the HMI symbol for the network pages to show the IP. Maybe i am doing something wrong..or some step is missing. Please let me know. Do i need to do something on the OPC or somewhere else?

Are you using the old or new PNSM server?
The old PNSM server have known issues with scaling a large number of SNMP assets and a reworked version was released for 6.0.3 some time ago.
The above problem (not limited to NEOS devices) has been addressed in the two below rollups:
6.0.3: System 800xA ABB PC Network and Software Monitoring 6.0.3-0 RU2 Release Notes, 2PAA117245
6.1.0: System 800xA ABB PC Network and Software Monitoring 6.1.0-0 RU1 Release Notes, 2PAA122105
These documents are, as most software published on ABB Library tagged "PREMIUM" for which ABB intranet access or an active ABB Sentinel Subscription is required. If you cannot access these links, please speak with your regional ABB sales representative.
