Abstract
The invention relates to an EtherCAT fieldbus system, a master and a slave for the system and a method. The slave is configured to be coupled to the EtherCAT fieldbus. A first configurable memory of the slave stores a first activation list indicating for consecutive bytes of data of an EtherCAT datagram a corresponding fieldbus memory management information or synchronization management information.
Claims18
A slave configured to be coupled to an Ethernet for Control Automation Technology (EtherCAT) bus comprising:
- a configurable memory storing a first activation list indicating for consecutive bytes of data of an EtherCAT datagram a corresponding fieldbus memory management information or synchronization management information.
A fieldbus system comprising:
- an Ethernet for Control Automation Technology (EtherCAT) bus;
- a master coupled to said EtherCat bus;
- a slave coupled to said EtherCat bus, said slave including a configurable memory storing a first activation list indicating for consecutive bytes of data of an EtherCAT datagram a corresponding fieldbus memory management information or synchronization management information.
A method of operating a fieldbus system comprising a master and a slave being coupled through an Ethernet for Control Automation Technology (EtherCAT) bus, the method comprising:
- configuring a first portion of a configurable memory of the slave so as to store a first activation list indicating for consecutive bytes of data of an EtherCAT datagram a corresponding fieldbus memory management information or synchronization management information.
