| titleOfInvention | Method and circuit arrangement for the transmission of data signals between control devices connected to one another via a loop system |
| abstract | ABSTRACT OF THE DISCLOSURE A method for transmitting data between a number of control devices which are connected to each other by at least one clock-controlled loop, which is operated directionally dependent, is disclosed which causes a transmit authorization signal to be sent via the loop from control device to control device which places each control device, upon receipt thereof, in a transmit authorization status. A control device receiving the transmit authorization signal emits data signals to be transmitted via the loop, together with a receiver address identifying a selected other control device intended to receive the data signals, before forwarding the transmit authorization signal to another control device. The control device which has transmitted the data signal is then switched to an acknowledgment signal reception status. If the intended other control device receives the data signals correctly, the receiving control device sends an acknowledgment signal to the transmitting control device. The transmitting control device is maintained in the acknowledg-ment signal reception status for a maximum time, which is defined by the renewed arrival of a further transmit authorization signal. If the transmitting control device receives the acknowledgment signal within the maximum time, that control device is then switched to a status enabling renewed emission of further data signals. If no acknowledgment signal is received within the maximum time, the transmitting control device is switched to an error status for either reporting the error or initiating steps to correct the error. This prevents a control device which has not received an acknowledgment signal from being out of the data transmission loop for an undefined period of time until the error is noticed by some other means. |
