摘要：A data processing and transmission system (1) for a numerical control unit (2)adapted to control a machine tool (3), comprises at least one input channel (4) adaptedto a transit of operational signals from or to devices present in the machine tool,electronic circuits configured to process the operational signals to make available on anoutput interface (5) control signals for the numerical control unit, a multipolar cable (8)having a first and a second end, each provided with a multipolar connector (9), a masterunit having the output interface, a main processor, a memory and at least one socket (7A)configured to be coupled to one of the multipolar connectors, one or more slave units(6), each provided with at least one external port (6A) defining the input channel, amemory, a secondary processor, and provided also with a first socket (6B) and a secondsocket (6C), configured to be coupled at least to a first or a second connector of themultipolar connectors in order to interconnect the slave unit at least with the masterunit. The master unit has a clock and each slave unit has its own clock. The main processordivides a data transmission time interval into a plurality of time slots an uniquely assignsto each slave unit a corresponding time slot of said plurality of time slots. The secondary
processor of each slave unit is set to transmit data through the multipolar cable onlywithin the respective time slot. Each slave unit can be connected to another slave unit todefine a modular structure.
