FIELD: engineering of controlling equipment for building structure of data processing devices which represent programmable logical controllers. ^ SUBSTANCE: data processing device contains processor for processing data, modules for input and output of data (not shown on the drawing), coupled by means of a bus with connection processors with possible usage of serial communications channel, connected to processor. Also, composition of input-output modules includes controlling processor programmed by user, which, except functions of input, output and primary signal processing performs various controlling functions autonomously and asynchronously in relation to processor or in parallel with it. In another variant of data processing device, a user-programmed controlling processor is included in each input-output module, and two connection processors which are connected to the controlling processor and the aforementioned bus. ^ EFFECT: increased reliability and reduced time of information processing in information processing device (in the controller itself), by means of, but not limited to, decentralization of various input-output and data processing functions. ^ 2 cl, 1 dwg |
