I'm evaluating the available interfaces for using Intouch 8 HMI with Concept and Quantum/Momentum PLCs.
I've been primarily using the KEPSERVER EX package. It directly supports Wonderware Suitelink protocol, and can auto generate a tag database from the Concept export files. However, it cannot read unlocated variables, nor can it access structured variables (in its current release).
Has anyone else evaluated this package against OFS, or the Wonderware MBENET IO Servers?
To use OFS, I would have to use the OPCLINK IO server from Wonderware. Personally I haven't had good experiences with DCOM and OPC. Plus, I'd have two pieces of software sitting between the PLCs and HMIs.
To use Wonderware's MBENET driver, I believe I'd have to maintain yet another database of names/addresses, and it wouldn't autogenerate.
Please comment if you have experience connecting these systems, and let me know what has worked best for you. I'll also need to serve data from the IO Server to InSQL. Comment here as well.
Thanks in advance for any information.
