OPC Servers

3 posts in this topic

Does anyone have a recommendation for an OPC server to connect to an AB compact Logix?   RS Links, KepServer, and Matrikon seem like the popular ones (I assume they are expensive and paid for by license).  I only need to manage a few Tags and I want to keep the cost down.  Any suggestions?

Thanks

Hello,

We have a low cost OPC server for Logix. And a low cost HMI.

We use ClearSCADA for the HMI and Kepware for the AB and Modbus server. I came from a Wonderware / AES environment. At this point if I was given a choice I would go with what we have. It still surprises me that we poll and historize as much data as we do (100's of thousands of points) with little to no issues.

 

Kepware is cheap compared to AES. It's a one time price to buy the server and unlimited points. AES is "point based". Kepware "talks" Allen Bradley CLX very well. It pulls the tagname database from the PLC. It will also talk to the legacy AB PLC's (SLC, PLC5).
