Does not work well….at least in 10.11.3

After downloading and trying Modbus Server (free) and learning it does not work in 10.11.3, I read the info on the Pro version and it indicates it works “10.6 or later.” So, I spent the $3.99 and have wasted a ton of time (and $3.99) trying to figure out how to create 8 input registers. There appears to be no way to (easily?) create and load 8 input registers. I can’t even create and load 8 holding registers. The server does start up and responds to inquiries. However, it’s basically worthless to me unless someone can tell me how to create the additional registers I need to simulate the device for which I’m writing an interface.

The help tool is nicely done, but is of little value, at least with regard to my needs.

I would even be happy to hack the .mbs file that holds the register settings if that information was provided.

Come on Contech—a little help, please!!!
