I have a cubloc cb290 on my mill for more I/O.To learn all this plc stuff I bought the cubloc study board and cb280.
It is sitting on my desk with the lights turning off and on nicely.I have written several "brains" that work fine on the cb280
and I think I get the whole thing.So I set up the cb 290 on my mill same way.It worked for about 1/2 hour, or at leasdt the
time out error never came up so I assume that I had com between Mach and the plc.Now all I get is time out errors.I ran a small looping progm on the plc to test and it seems to work fine.
Any ideas on how to get Mach and the plc to get along.
I have tried usb/serial cable that works on my cb280 and a pci serial card that also works with the 280.
The 280 is connected to a differant computer.I have the latest version of mach.

I don't know much about the cubloc controls on the computer your having troubles be sure to use the modbus serial plugin is much easer and watch the refresh rate in the setup with the use of usb converters you may have to decrees the refresh times

On the Cb290 I read there is two rs232 channels 0 is 12v voltage and channel 1 is TTL and 12V use the TTL channel
