Method for sending EtherCAT telegrams from an EtherCAT master to a number of EtherCAT slaves and EtherCAT masters

摘要

Method for sending EtherCAT telegrams from an EtherCAT master (10) to a number of EtherCAT slaves (20), - the EtherCAT master (10) having a Media Access Control (MAC) unit (11) for media access control has a carrier sense (CRS) connection (12),- the MAC unit (11) not initiating any transmission of EtherCAT telegrams when a signal at the CRS connection (12) has a blocking level and the MAC unit ( 11) at an enable level of the signal at the CRS connection (12) initiates a transmission of EtherCAT telegrams, if there are EtherCAT telegrams to be transmitted, the method having the steps:- Generating a clock signal (TS) at the CRS connection (12), wherein the clock signal (TS) alternately has the inhibit level and the enable level.
