I have an old machine that has a control that the grinder company developed Swiss Axesta/ Grossenbacher cnc control components. It is a late 90's machine but the technology behind it seems like early 90's. As far as I can tell it is very simple. It is an Intel microprocessor based control and all data is stored on Eproms. The question is should I back the Eproms up like I would a hard drive? Are they likely to fail? Am I likely to screw them up trying to read them?
As far as I can see there is no way to see or get data out through the operator console on control unless there is a secret maintenance mode. I have or can get all the boards for the control but if somehow I lost the actual programming/ ladder/ parameters that drive it the machine would likely be a boat anchor.
The machine has a Siemens PLC and a uses Siemens Simodrives which are readily available, just the custom control part of the machine seems sketchy.
