    摘要： A synchronous data transmission device for transmitting data (D, D') between two communications partners (K1, K2), one functioning as a transmitter and one as a receiver, is described. The device is capable of transmitting information regarding an occurring transmitter-side event (E
    s , Es') to the receiver as quickly as possible, and comprises: an event monitor (11, 11'), which monitors the occurrence of at least one predetermined event (E) on the transmitter side and, upon the occurrence of one of these events (E), displays the occurring event as a transmitter-side occurring event (Es, Es') during the occurrence thereof; a clock generator (13, 13') with an adjustable clock frequency, which is connected to the event monitor (11, 11') and generates a transmission clock signal (clk, clk') with a transmission clock rate (fs, fs') that is equal during the occurrence of one of the events (E, E') to an event-specific transmission clock rate (fE1, fE2, fΕ1') assigned to the occurring event (Es, Es'), and is equal to a base clock rate (f0) different from all event-specific clock rates (fE1, fE2, fΕ1') during an event-free period of time; a transmission device (9), which transmits data signals (DS, DS'), which correspond to the data (D, D') to be transmitted, from the transmitter to the receiver at the transmission clock rate (fs, fs') and transmits the transmission clock signal (clk, clk') from the transmitter to the receiver; and a receiver-side event recognition device (21, 21'), which is connected to the transmission device (9) and recognises a transmitter-side occurrence of one of the events (E, E') on the basis of the transmission clock rate (fs, fs') of the transmission clock signal (clk, clk'), and determines and outputs the event (Es, Es') upon the occurrence thereof.

    摘要： The invention relates to a method for operating a field device (T1, T2) of process automation technology, wherein data are exchanged by means of at least one protocol between the field device (F1, F2) and a control program (P1, P2, P3, P4), wherein the protocol has base commands via which base commands base functions (F1, F2, F3, F4) of the field device are called up, each field device (T1, T2) compatible with the protocol having said base functions (F1, F2, F3, F4), wherein only base commands of the protocol are used to transfer data between the control program (P1, P2, P3, P4) and the field device (T1, T2).
