Get state of EtherCAT network
The EtherCAT Get State block returns the state of the EtherCAT® network.
State— State received from the EtherCAT network
|1||Initialization – The system finds slave devices and initializes the communication controller.|
|2||Preoperational — The system uses the communication controller to exchange system-specific initialization data. In this state, the network cannot transmit or receive signal data.|
|4||Safe operational — The network is running and ready for full operation. The master sends input data to the slave device. The slave device output remains in a safe state.|
|8||Operational — The network is in full operation. The master sends input data to the slave device. The slave device responds with output data.|
