Description

The EtherCAT Get State block returns the state of the EtherCAT^® network.

Examples

Output

State — State received from the EtherCAT network

1 | 2 | 4 | 8

State	Value	Description
INIT	1	Initialization — The system finds terminal devices and initializes the communication controller.
PREOP	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.
SAFEOP	4	Safe 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.
OP	8	Operational — The network is in full operation. The supervisor sends input data to the terminal device. The terminal device responds with output data.

Parameters

Network Device Index — EtherCAT network identifier

0 (default) | 0-11

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

Sample time — Sample time of block

-1 (default) | numeric

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

Programmatic Use

Block Parameter: sample_time
