Mach4 modbus plugin problems
« on: September 11, 2017, 01:07:34 PM »
I'm having an issue with the Mach4 Modbus plugin. When I go to set up a new modbus serial connection, it is not giving me any options for the serial port. The "port" dropdown is completely blank. I know there are two serial ports in the computer as they show up in the Serial plugin config. I tried it on a different computer and the ports show up correctly. I am using version 3481.

Anyone gave any thoughts?

Thanks
Keith

Hi Keith,
haven't had any problem here with an earlier build.

I'm trying to replicate what your are doing:
1) Configure/Plugins/Modbus
2) Click Add NEW Modbus Connection icon top left
3) Name, Description and Type <Next>
4) Enter Serial Com properties, check 485 <Next>
5) Confirm <Finish> or <Cancel>


I have these three screenshots of 3),4),5)    Do they match what you see?

Thanks for your help. I can get as far as the second screen shot but that is where the Port menu is not populated. I have attached a screen shot. I thought at first that for some reason the plugin did not like the built in serial ports on the computer so I tried an external USB serial port with the same result. The computer itself does detect the serial ports as I can use them using Teraterm. The "Serial" plugin in Mach4 also sees them as well. It is just the Modbus plugin that is having the issue.

Just as an update I have found and fixed the problem. In my windows 7 setup there were several services that were turned off, one of which was causing the problem. I'm not sure which one was the issue but when I set them all back to the default state the problem went away.
