StateValueDescription
INIT1Initialization — The system finds terminal devices and initializes the communication controller.
PREOP2Preoperational — The system uses the communication controller to exchange system-specific initialization data. In this state, the network cannot transmit or receive signal data.
SAFEOP4Safe operational — The network is running and ready for full operation. The supervisor sends input data to the terminal device. The terminal device output remains in a safe state.
OP8Operational — The network is in full operation. The supervisor sends input data to the terminal device. The terminal device responds with output data.

Parameters

To associate a block with an EtherCAT network, enter the Network Device Index value from the EtherCAT Init block representing that network into the Network Device Index for the block.

Programmatic Use

Block Parameter: device_id

Select an EtherCAT subordinate device from the list of available subordinate devices provided by the ENI configuration file. The configuration file is selected by the EtherCAT Init block.

Programmatic Use

Block Parameter: device_name

Enter the base sample time or a multiple of the base sample time. -1 means that the sample time is inherited.
