ABSTRACT:
A symbol definition system for a programmable machine controller (PMC) for defining symbols (signal names) in a sequence program of the PMC. Since the function of the signals between the PMC and a numerical control apparatus is fixed, a first group of symbols is supplied to a program creation unit as system data, and therefore, when a sequence program is created, the first group of symbols need not be defined. Further, the first group of symbols is transferred to the PMC together with the sequence program and used for editing and maintenance.
