hum,
I opened both the Serial and TCP modbus pages - they all show the value as zero (expected as I don't have modbus and have never used the pages) - I then clicked the update button on each item to  make sure they were set to zero...  I also looked thru all the other pages for an out of range value - didn't fin any.

I still get the dialog when exiting mach...   

Dave

Dave,

Also check the Mad Message, it is the menu item under plugin control that is under Mach MAD.....
the first page on that, also has modbus cfgs. that range 0-128 check them.

the range 0-128 is only for the Modbus local vars on both TCP and Serial, it is the only place that
range restriction exist.

If that doesnt fix it, then pehaps uninstall and reinstall MAD, (and mabey Mach3).

Scott -
that fixed it.
The Local MB entries were all set to 1024 for some reason - I changed them to 128=NoUSe and the dialog went away.

Thanks
Dave

Will  Mach MAD plug in (Maintenance and Diagnostics ) help with  faults which require you to Reset mach, the problem is very intermittant 

Having problems with Mach 3 with something intermittant requiring a reset, will Mach Mad indicate what caused the need to reset Mach3 i.e. if a limit switch caused the problem do you see a latched Led for instance. Does the above make sense.

Denis

Will this plugin allow me to modify Mach3 2010 Screen set?
