800xa opc client
I have a 800xa 5.1 system and I want to install a 3rd party opc client software on a separated PC to read from 800xa some data.
Am I need a licence for it or it'll works.
Is there any procedure to configure the AS (DCOM) to allow read from another domain?
Thank's in advance.
There is a licence item to purchase for third party OPC Connection to System 800xA.
Search AKS for suggestions for DCOM settings. I have attached a document explaining the need for two accounts (local+domain) when bidirectional (asynchronous) OPC is required. Do not use the 800xA service account.
I have also attached a document describing methods of subscription. For performance, use asynchronous advise based subscription, or read synchronous from cache/with active groups/items.
Always check performance recommendations for the source OPC server. Some servers have recommendations that should be adhered to, eg 800xA for Advant Master.
