StateValueDescription
INIT1Initialization – The system finds slave 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 master sends input data to the slave device. The slave device output remains in a safe state.
OP8Operational — The network is in full operation. The master sends input data to the slave device. The slave device responds with output data.

Output

This port transmits the value of the previous setting of the New State port.

If no error occurs, this port transmits 0. Otherwise, it transmits a nonzero value.

Parameters

To associate a block with an EtherCAT network, copy the Device index value from the EtherCAT Init block representing that network into the Device index for the block.

Enter the number of seconds to wait for the EtherCAT network state to transition.

Set the timeout to 0 to return immediately.

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