摘要：The circuit contains two random-access memories or storages into which thereis alternately written-in data received from a process computer. The data, in addition tothe related addresses, is read-out at two intermediate storages or memories whichdeliver, by means of a digital-to- analog converter which can be set by a channel selectionswitch to the correlated analog channel, analog control-and-regulation signals for amachine tool. Two reversing switches which can be alternately opposingly switchedenable writing into the one random-access memory, whereas the other random-accessmemory is read. A further reversing switch switches to the related channel address- andchannel data intermediate storage. The circuit has 20 to 64 differential analog outputchannels with maximum signal voltages of .+-.10 volts. The resolution of the analog signalamounts to 16-bits, resulting in quasi- continuous analog output voltage signals (voltagesteps or stages in the signal of minimum 0.3 mV), which can be reliably used in theregulation circuits of a machine tool.
