Abstract
An input/output unit for data acquisition in a field bus system includes a microcontroller that has at least one integrated synchronous serial bus interface and a control device for direct memory access. A signal source for a digital signal is connectable to a digital data input master input, slave output (MISO) of the at least one synchronous serial bus interface. The first synchronous serial interface reads in the digital signal present at the data input MISO at a first clock rate that corresponds to a data transmission rate of the at least one synchronous serial bus interface. The control device for direct memory access forwards the read-in data words to a buffer memory, and periodically fetches the read-in data words from the buffer memory and forwards the read-in data words to a second synchronous serial bus interface or to another bus interface.
