[milo-dev] 回复： 回复： Does client/server SDK of Eclipse Milo support Security/AE/HDA function
Hi,

Thanks for your help!
I checked with Keapware.
In KEPServer UA engine, only Data Access is included, no AC and HA as OPC UA spec defines.

Hi,

 

I couldn’t get history access with kepware UA working. I have same impression

that it is just not supported (yet, I hope). I switched to use unified automation

UaAnsiCServer demo for my testing, it seems to work well.

I may be wrong about this, but I don't think Kepware supports UA historical access. I think their historian only supports OPC Classic/DCOM history. You may want to check with them.

Hi,

 

I am a new comer of OPC and KEP Server.

About OPC HDA function, have encountered a new problem: "The server does not support the requested service". (Access OPC UA URL: opc.tcp://192.168.0.4:49320).

 

Does KEP Server use a different URL or port for HDA? In KEP Server (V6.0.2107.0),  the HDA function is enabled, how to access HDA server?

 

In KEPServerEX Settings, find Local Historian default port: 57012, but the LISTENING address in windows is127.0.0.1:57012.  The IP is local, Can't be connected by another PC.

 

Does anyone know the config and access method for HDA?

Hi,

 

I think that you need to use suitable derived HistoryReadDetails class, for example

ReadRawModifiedDetails. I have something like this In my (working code):

 

HistoryReadDetails hrd = new ReadRawModifiedDetails(false, begin, end, uint(0), false);

CompletableFuture<HistoryReadResponse> resp = client.historyRead(hrd, TimestampsToReturn.Server, false, readIds);

Hi, 

 

About HDA question, tesing code:

List<NodeId> nodeIds = ImmutableList.of(new NodeId(2, "ChannelTest.DeviceTest.Tag190"));
List<HistoryReadValueId> nodesToRead = new ArrayList<HistoryReadValueId>();
HistoryReadValueId valueId = new HistoryReadValueId(nodeIds.get(0), null, null, null);
nodesToRead.add(valueId);
CompletableFuture<HistoryReadResponse> historyResp = client.historyRead(new HistoryReadDetails(), TimestampsToReturn.Both, true, nodesToRead);

 But can't read history data.

Hi,

 

I want to test AE with Milo client and KEP Server,  and have some API questions.

For example, How to write the 4th parameter "_continuationPoint" of HistoryReadValueID constructor?

Does "client.historyRead" method need a monitor? The invoke will be block when reading?

 

Thanks!

Best regards, 

George Ray

The client supports everything. There's no examples for subscribing to alarms or calling history, but it's really just a matter of putting together the right request objects and invoking the service. Part 4 of the spec can help with this.

 

The server does not yet support events (so no AE). It does have stubs for implementing the history service calls (as of a few days ago), but that's up to your implementation to fulfill if you choose to support it.

if support, is there any reference example for the function？

 

Thanks!
