Hi Team,
We are using Prosys SDK-v2.2. The client is using Loytec LINX-215 device where the server is installed. While reading the history from server by using below api

AccessController.doPrivileged((PrivilegedExceptionAction)() ->
{
UaClient.historyReadRaw(node_id, start_time, end_time, UnsignedInteger.valueOf(1000), true, null, TimestampsToReturn.Source);
});
catch (Exception e)
{
e.printStackTrace();
}

we are getting exception as below

Caused by: com.prosysopc.ua.StatusException: Bad_NotReadable (0x803A0000) “The access level does not allow reading or subscribing to the Node.” StatusCode=Bad_NotReadable (0x803A0000) “The access level does not allow reading or subscribing to the Node.”
at com.prosysopc.ua.client.UaClient.checkOperationResult(Unknown Source)
at com.prosysopc.ua.client.UaClient.a(Unknown Source)
at com.prosysopc.ua.client.UaClient.historyReadRaw(Unknown Source)

Could you please advice what is the cause, because of which we are getting exception.

The same code is working fine with other Prosys server.

Thanks,
Bibhu

Hello,

Please verify that the Node you’re trying to read history from has the HistoryRead bit set to 1 in AccessLevel and UserAccessLevel Attributes. Otherwise the historyReadRaw method may not work.
