A dead mans grip would had been good. This is one of the few cases there I would trust software as an active signal passing a rather complex chain sequence is needed to get things moving, this have less to do with the software and more with the hardware since it's impossible to check if it might

Hi John, The mb2hal config file is standard ini format, the same as your config ini file. As you can specify the ini file it allows you to use either the config ini file or a separate file. It is not in any way compatible with hal files. Les Then if it's designed to be included into a .hal

Re: [Emc-users] Homann Designs ModIO

With how cheap realtime i/o is - I don't see the a lure of modbus. Modbus non-realtime should be plenty fast enough for spindle control unless you are doing position control of the spindle. I'm not sure about RTAI but if you are using preempt-rt mb2hal should be pretty close to real time. I

My 2 cents. For some things non-realtime i/o is fine. I have seen too many times where someone is maybe controlling a spindle and wonders why a change in direction takes so long and or isn't consistent. Once they switch over to something realtime (+/-10v or pwm) the issue goes away. With how ch

The MB2HAL module should be able to talk to it . I/O should be no problem but the display may be a bit awkward. Les On 06/02/2020 07:43, John Dammeyer wrote: The wiki for this is out of date. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ModIO

This might help but it may be out of date as well: http://linuxcnc.org/docs/2.7/html/drivers/mb2hal.html basically, at the time, a working modbus vfd driver was edited to use modio registers instead of the vfd registers. There has been other independent work done on linuxcnc so searching the
