Have a customer with their older truck/bus touchless wash. We've been able to keep it going, until now. There is a touchscreen interface that has proprietary software in it that enables it to talk to the plc. The company that made the touchscreen does not support that version anymore, and Speciality went belly up several years ago. As much as I would like to sell them a new machine (Istobal makes a kick butt unit) I would like to see if we can keep this going a little longer. Anyone know where I can get the software?
