Description

See also: EtherCAT States And Its Identifier

The Xentara EtherCAT Device object represents the physical EtherCAT slaves such as EK1100. Each device includes an EtherCAT Slave Controller ESC, which includes a state machine. Certain functionality and features are available depending on the state of the device. Children of the Xentara EtherCAT device object can be Module objects or Entry objects. That is, either the device will have the data (Entry) or it will act as a coupler for various modules, which will then have the data (Entry). It is also possible to have data inside the device as well as modules.

ESI and ENI Files

See also: Device Information Application

A device description document in XML format called the EtherCAT Slave Information file (ESI) is provided for every EtherCAT device. The ESI file provides details on the settings and functionality of the device. It provides all the information about Entry data objects. ESI files are used by the EtherCAT configuration tool to compile network information (ENI) in offline mode (e.g. process data structures, initialization commands).

Accessing Device

In addition to the standard members of Xentara I/O Component, Device have the following attributes:

Attributes

position	The position of the device in the topology.
slotIndexIncrement	The increment value for the module's indexes connected to the device.

The devices also provide access to the bus's attributes.
