ABSTRACT:
A modular, numerical control includes at least two modules, each including a microprocessor unit and being connected to each other via serial data-transmission channels for the transmission of information in the form of data packets. In at least one module, a data-packet generating unit is provided for generating data packets and for transmitting data packets to at least one further module. In so doing, the data-packet generating unit operates independently of the function of the microprocessor unit. Moreover, in at least one module, a data-packet processing unit is provided by which data packets are able to be processed and/or are able to be transmitted to at least one further module, independently of the function of the microprocessor unit. The data packets include the status of at least one safety signal.
