Abstract
The invention provides a circuit apparatus having a circuit core module (100), a controller processor unit (102) for driving and addressing the circuit core module (100) and a data transmission unit (103a) for transmitting data between the circuit core module (100) and at least one external circuit module (110), provision being made of at least one further data transmission unit (103b-103n) that is of redundant design with respect to the data processing unit (103a), a data stream being changed over between the circuit core module (100) and the data transmission units (103a-103n) of multiply redundant design by means of a first changeover unit (201) and a data stream being changed over between the data transmission units (103a-103n) of multiply redundant design and the at least one external circuit module (110) by means of a second changeover unit (202).
