STATE LED

Near the EtherCAT Connector A there is a STATE LED that can be in one of the following situations:

State	Slave Condition	Communication
Off	Init	After switch-on the EtherCAT slave is in the Init state. No SDOor PDO communication is possible.
Blinking	Pre-Operational	In Pre-Operational state SDO communication is possible, but not PDOcommunication.
Single Flash	Safe-Operational	In Safe-Operational state SDOand PDO communication is possible, although the slave keeps its outputs (RPDO) in a safe state, while the input (TPDO) data are updated cyclically.
On	Operational	In the Operational state the slave copies the output data of the masters to its outputs (RPDO). PDO PDO and SDO communication is possible.
