I'm going to answer my own question for the sake of some other poor soul that may not be able to find what they need. After a lot of checking around it seems that there are pretty much two options regarding monitoring and MTConnect.
1. The first option is to get MTConnect installed and running for the machines. The only way I found to do this is contact Fagor and talk to the person that knows whats up with MTConnect. He apparently can install the adapter and agent remotely, either on the controller, or on a host PC, depending on the model of the controller. At this point, we would have MTConnect data, but would still need something for monitoring. This leads me to a questions then my second option:
Question: Does someone have experience with a free or low cost option for monitoring MTConnect data? I'm only looking for one measurement right now - OEE. As a very small shop, we aren't quite ready to drop 20-40k on a full-suite monitoring software.
2. The second option is to get a full-suite monitoring software. Some of them require MTConnect data, others can communicate with your controller using the controller's native protocol. The upside with this is that you get a whole host of capabilities including DNC, detailed reporting, ERP integration, tablets for entering downtime reason codes, etc. The downside is the cost, which despite encouraging ROI calculations, is still a chunk to bite off, especially if cashflow is an issue.
