LEDs for EtherCAT State Machine/PLC Diagnosis

LEDs		Display	Status	Description
Run	Green	Off	Init	State of the EtherCATEtherCAT 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 MachineThe complete assembly of all connected parts or devices, of which at least one is movable: INIT = Initialization
		Blinking	Pre-operational	State of the EtherCAT State Machine: PREOP = Pre-Operational
		Single Flash	Safe operational	State of the EtherCAT State Machine: SAFEOP = Safe-Operational
		On	Operational	State of the EtherCAT State Machine: OP = Operational
		Flashes	Bootstrap	State of the EtherCAT State Machine: BOOT = Bootstrap (Update of the coupler firmware)
Error	Red	Off	—	No errors
Error	Red	Blinking	Err-Operational No Communication	PLC"Programmable Logic Controller" A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events error / Lost frames
