ABSTRACT:
An analog signal which occurs in a computer controlled machine tool is converted to digital form at the machine tool site and is stored in a memory portion of the machine tool computer. The digitized analog signal is subsequently read out of the memory and is transmitted to a remote diagnostic unit via a conventional digital transmission link. The digitized analog signal received by the diagnostic unit is stored in a memory portion of the diagnostic computer and is subsequently read out and converted back to analog form for display on an oscilloscope in the diagnostic unit to aid in the diagnosis of existing or incipient faults in the machine tool.
