Can you run Plasmac offline

Is it possible to open Plasmac without Ethernet (Mesa 7i76e) connected?  I would like to be able to open Plasmac without being down in the shed with the machine.

It just crashes with a big messy warning that somewhere in there says 'network unreachable'.  Actually that is a gripe for me!  If my machine is not powered up rather than just a nice message 'cannot communicate', it just dumps a big mess on the screen that you have to scroll through too see what is going on.  Seems like a pretty common error that could justify a nice descriptive warning.  Or even wait for the machine to bee turned on, then carry on.  Just saying...
 

You should create some "simulating" configuration that doesn't include any external hardware. After this you can work with this simulation environment

Short answer no. You cannot open a gui if the mesa device is not found.
There is a QTplasmac simulation available in your control panel.

Thanks everybody for your replies.  I will use one of those options to set it up so I can open PlasmaC without being at the machine.

The workflow I used was to map a file share to the machine and save my cut file direct from the postprocessor (sheetcam) into the nc_files folder
then visit the machine and hit the load latest button(check the docs on this.)
I was not keen on starting a cut without being at the machine
