I have SAS ESP installed on Server. I have OPC UA Server. OPC TCP Port opened between SAS ESP Server and OPC UA Server.

I want to use OPC UA Connector as my source for the data.

It is really confusing where to do what.

Any kind of certificate required to apply on both servers ? 

Can someone guide me step by step to do the same.

Tech Support(TS) investigated this. The commas in the nodeid were causing issues parsing the nodeid.  A patch is available from TS to support a nodeid with commas in it.  Contact SAS Tech Support if you need the patch.

 The SAS ESP 5.2 User Documentation has an entire section on configuring and using the OPC-UA adaptor, found here: ESP 5.2 User Guide: OPC-UA. It sounds like you are using the OPC-UA adaptor as a Publisher of data to ESP, which is covered in the user guide. There is a section that describes all of the settings and parameters supported by the adaptor as a publisher. Are you seeing an error message? Please provide here if so to help with any sort of guidance.

1] I have updated the "opcnamespaceuri" and  "opcuanodeids"  parameters for opcua publisher connector (INPUT) as urn:Yokogawa:FASTTOOLS_UA_SERVER and s_{"0":"Value","itnm":"BALAWALA.PROCESS.HDR1_FLOW"} respectively.

 

2] Also defined output schema.

 

3] While testing continuous query we are getting error "invalid value for parameter opcuanodeids".

 

4] We have verified the same node id from UA Expert (Third Party OPC UA Server Client) and it is working fine.

 

5] The problem is the nodeid which I want to access already contains comma and underscore which are reserved for opcuanodeids parameter in SAS ESP (I think so).

 

6] Nodeids are automatically generated in OPC UA Server with which I am trying to connect. So, it can not be changed, I checked same with OPC UA Server team.

 

7] I have replaced "comma" and "underscore" with 8 bit hexadecimal ANSI encoding (%2C and %5F) in the nodeids since both the character are reserved in ESP nodeid parameter. But still it is giving invalid opcuanodeid error. (Tried this because I got some specification documents online regarding OPC Foundation).

 

For example, s_{"0":"Value"%2C"itnm":"BALAWALA.PROCESS.HDR1%5FFLOW"} is the nodeid which we are trying to map.

 

8] These nodeids with ANSI encoded characters works fine in Third Party OPC UA Server Client  (UAExpert).

 

Now I have a question is it necessary to apply certificate to establish connectivity ?

I have certificate (".der" file) provided by OPC UA Server Team. 

 

Error Screenshot is attached for your reference.

 

I want to access data from that OPC UA Server only (no other option).

 

I would appreciate any kind of help since this is the only hurdle I am facing.

 

Thanks in Advance

 Thanks Andy,

 

I had raised ticket for the same. I have got the hotfix from SAS Tech Support for the same.

This hotfix added a new parameter called "opcuanodeiddelimiter" for OPC UA Connector/Adapter in SAS ESP.

This was the special case Smiley Happy
