State of the EtherCAT***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs State Machine: INIT = Initialization of the terminal or BOOTSTRAP = Function for firmware updates of the terminal |
|||
blinking |
State of the EtherCAT State Machine: PREOP = Setting for mailbox communication and variant standard settings |
|||
single flash |
State of the EtherCAT State Machine: SAFEOP = Channel checking of the Sync Manager and the Distributed Clocks. Outputs stay in safe operation mode. |
|||
on |
State of the EtherCAT State Machine: OP = Normal operation mode, mailbox- and process data communication possible |
