BETRIEBSSYSTEM FÜR DIE STEUERUNG MIT NUMERISCHEN DATEN

摘要

Each CNC (10,20) comprises a CNC control section (11,21) a switch circuit (12,22) for input/output signals, a RAM (13,23) connected to the switch circuit (12,22) for storing the input/output signals, and a PMC (programmable machine controller) (16,26) connected to the RAM (13,23), and a serial transfer control circuit (15,25) which are connected to the RAMs (13, 23) and transfer the input/output signals with other CNCs. The PMC (16) is designed so that it can receive the input/output signals of other CNC (20) by the serial transfer control circuit (15) or can transmit them. The CNCs (10,20) can receive or send their input and output signals through the transfer control circuits (15,25). @(15pp Dwg.No.1/2)@.
