Currently doing some retrofits of KMX machines, this customer still wants carts with the HMI mounted on the cart. After the setup is complete they unplug it and store it.
Any offsets required are dialed in on the operator console.
The operators have no need to see a screen as the machine has large capacity bar feeders and run forever on a job.
Of course the new cart has tcp/ip connections.
Also,am working with a customer on retrofitting three spinning machines which will load via robot, same thing no hmi at the machine except for setup.
