I remember that there was some problem with Modbus module which I thought was solved by ArcEye. (Maybe he will chime in.) But given that it was the so called "userspace" component, it would be in machinekit-cnc, not machinekit-hal. But it doesn't look like it is there.
The problem with mb2hal is that it presents itself as a non-real-time component (Modbus is generally considered as a non-RT), but as far as I know the Modbus RTU can be used in RT, the TCP because of inner working of TCP communication cannot. Given the "RT" and "userspace" components definition in Machinekit is a prehistoric vintage from LinuxCNC which outlived it's usefuness, maybe it is time to have something capable both of RT and non-RT functioning. I am planning something for which I will need the modbus communication, problem is, I plan in years. Cern.
