摘要
Digital data processing system for fail-safe automation to the embodiment as a function - and flowsheets shown programs, wherein each lapse of flat step, a constant execution time frame is available, with two channels, each with two computers, wherein in each channel respectively the first computer (function - and outlet planar processor) for the processing of data flows and step sequences and the second computer (function block processor) for processing function block is used to call, wherein the at the high-level languages function - and flowsheets, and oriented only direct and direct addressing be used in the instruction set of the first computer (function - and outlet planar processor) of six unconditional and two conditional data transfer instructions, which permit no other possibilities of the program branch occurs, as the embodiment of the current step assigned code to be repeated or to the beginning of the code segment of a step of jumping on the other, whereby in the second computer (function block processor) of the code in a single type as correct proven function blocks for the production of unalterable read-only memories (rom) is deposited, and wherein the in each case two computer for the exchange of data..
