Safety-related data transmitting method for e.g. Ethernet network, involves comparing block diagrams produced in transmitter with graphic block diagrams transmitted from receiver to transmitter

摘要

The method involves transmitting safety-relevant data (7, 9, 13) from a transmitter (1) to a receiver (10) over a transmitter-side arranged interface (6). A machine control program representable in block diagrams is produced by the transmitter, in which the program is transmitted to the receiver by a transmitter-side arranged compiler (4). The receiver receives the combined software program. The block diagrams produced in the transmitter is compared with graphic block diagrams transmitted from the receiver to the transmitter. An independent claim is also included for a device for transmitting safety-related data over an uncertain network.
