When I do a search on your web page for a solution, I am sometimes given two modules, a 3150/3100 module, and an MVI module. What is the difference?

The 3100/3150 product line is our original module line. We now provide our modules on an upgraded hardware platform, the MVI, which provides many improvements over the 3100/3150 hardware platform. Some of the new features the MVI modules offer are:

• On board Debug port which allow the user to view communication and configuration status of the module.
• On most modules, a built-in Data Analyzer is available, which assists the user in tracking down communication problems on their industrial network.
• Ability to field upgrade the module, so that new versions of the firmware can be flashed to the module without the need to return the module to the factory.
