Abstract
An automation system includes a control device, a system bus, a first field device, and a second field device. The control device includes a system bus interface for communication with the field devices by the system bus, and each field device includes a data interface for communication by the system bus. Each field device includes a monitoring input for receiving a monitoring signal and a monitoring output for outputting a monitoring signal. The monitoring input of the first field device is coupled to the monitoring output of the second field device by the system bus, and the monitoring input of the second field device is coupled to the monitoring output of the first field device by the system bus.
Claims17
An automation system, comprising:
- a system bus;
- a first field device;
- a second field device;
- and
- a control device including a system bus interface adapted to communicate with the field devices via the system bus;
- wherein each field device includes a data interface adapted to communicate via the system bus;
- wherein field device includes a monitoring input adapted to receive a monitoring signal and a monitoring output adapted to output a monitoring signal;
- wherein the monitoring input of the first field device is coupled to the monitoring output of the second field device by the system bus;
- wherein the monitoring input of the second field device is coupled to the monitoring output of the first field device by the system bus;
- and
- wherein each field device includes a configuration unit adapted to switch the field device to a parallel operating mode or to a slave operating mode in dependence on configuration data, a field device in the parallel operating mode adapted to output a monitoring signal by the monitoring output and to receive a monitoring signal by the monitoring input, a field device in the slave operating mode adapted to output a monitoring signal by the data interface and to receive a monitoring signal by the data interface.
