Benefits
From OPC Labs Knowledge Base
Support
- We respond to every post on our Online Forums (http://www.opclabs.com/forum/index).
- As opposed to many other vendors, our technical support is public, which means that any possible issues are visible on the Web and you can find them - and an advise on how to resolve them - without having to become a customer first. If your issue involves sensitive or confidential information, we can provide support to you via email.
Costs
- no need to pay yearly to OPCF to stay closed-source. It gets cheaper to purchase the toolkit rather than paying annual OPC Foundation fees.

- Pre-installation of OPC Core Component not required
- Pre-installation of UA Certificate Generator not required
- No need to create/assign a certificate by a manual process
- You can specify namespace URIs for OPC UA nodes
- ... and not namespaces indices. This is important, because the server can can change namespace indices between sessions. Other toolkits largely ignore this, and even give you examples where the node is specified with a hard-coded namespace index. Proper way of doing this is to look up the namespace index that corresponds to namespace URI, but that complicates the user code a lot. QuickOPC does this for you.
- any node/item descriptor can specify either a node ID, or browse path, or both
- UA complex data
- NuGet
- app. deployment fully documented, and production installer that actually works (and does not install into undocumented directories etc.)
- stable product build process
- no need to pay early to OPCF to stay closed-source
- slow down UA keep-alive mechanisms when debugging
- method overloads for short code
- clear exception model
- assemblies have strong names
- our installable and all bineries are code-signed (some security environments do not allow any unsigned code; OPCF does not sign).
