Description

The EtherCAT Set Device State block sets the state of a device on the EtherCAT^® network to the value passed through the New State port.

Examples

EtherCAT Protocol with Beckhoff Analog IO Subordinate Devices EL3062 and EL4002

Communicate with EtherCAT devices using the Beckhoff® analog I/O terminals EL3062 and EL4002.

Ports

Input

New State — State transmitted to 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.

Enable — Enables block to send state request

0 | 1

The port takes a Boolean value. When true (1), the block sends a new state request. When false (0), the block does nothing.

Output

Prev State — Previous state of the selected device

1 | 2 | 4 | 8

This port returns the value of the previous state of the device. That value might not be the same as the previous state of this block.

Error — Report an EtherCAT state error

0 | integer

If no error occurs, this port returns 0. Otherwise, it returns a nonzero value. For more information, see EtherCAT Error Codes.

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

SubDevice Name — Name of EtherCAT subordinate device

character vector

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

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
