Tab 'EtherCAT Slave - Startup Parameters'

Object: EtherCAT Slave

The SDOs (Service Data Objects) or IDNs that transmit specified parameters to the device at the system start are defined for the current slave in this tab.

The object directory with the required data objects is described in the EtherCAT-ML description file or in an EDS file which is referenced in the XML file.

Requirement: The device supports CAN over EtherCAT or Servodrive over EtherCAT.

Note

Some modules that are inserted below a slave have their own start parameters. These parameters are then also shown in this list but cannot be edited here. The parameters are changed in the editor of the corresponding module.

SDO table

List of the SDOs or IDNs

The order (from top to bottom) in the SDO table specifies the order in which the SDOs are transferred to the module.

Line

Line number

Idn

Bit Length

Bit length of the SDO

Abort on Error

: The transfer is interrupted in the case of an error with error status.

Jump to Line on Error

: In case of error the transfer is resumed with the SDO at the specified Line.

Next Line

: The transfer is resumed with the SDO at the next line.

Comment

Input field for comment

Move Up

Moves the selected line upwards by one line

Move Down

Moves the selected line downwards by one line

Add

Opens the dialog Select an entry from the object directory. In this dialog you can change the parameters of the SDO before the SDO is added to the configuration.

By specifying new index/subindex entries, a new object can be added to the SDO that is not yet described in the EDS file. This is useful if only an incomplete object directory or none at all is present.

Delete

Removes the selected entry.

Change

Opens the dialog Select Item from Object Directory in order to change the parameters of the selected SDOs or IDNs in the table

Servodrive over EtherCAT

Select Item from Object Directory

List of the available object directory entries as defined in the XML file.

Column Idn

Column Base value

Basic value of the IDN,

Editable, (open with double click)

Input fields

IDN

  • S

  • P

PSet

By specifying new PSeT/Offset entries, a new object can be added to the IDN that is not yet described in the XML file. This is useful if only an incomplete object directory or none at all is present.

Offset

By specifying new PSet/Offset entries, a new object can be added to the IDN that is not yet described in the XML file. This is useful if only an incomplete object directory or none at all is present.

Bit length

Drop-down list for the selection of the bit length

Value

Drop-down list for the selection of the value

Channel

This drop-down list is automatically displayed if the object has several sub-objects.

As list

Parameters are loaded as a list. The first four bytes indicate the length.

: The length is calculated automatically.

CAN over EtherCAT

Select an Entry from the Object Directory

List of the available object directory entries as defined in the EDS file.

Column Flags

Display of access flags: RW (read/write), RO (read only), WO (write only)

Column Base value

Editable (open with double click)

Input fields

Name

Input field for displaying and changing the name

Index: 16#

By specifying new index/subindex entries, a new object can be added to the SDO that is not yet described in the EDS file.

Subindex: 16#

Bit length

Value range of the object

Value

The size of each value can be maximum one byte (0-255). It can also be a hexadecimal in IEC syntax (for example, 16#ad).

If the Byte array option is enabled, then the values have to be specified as a comma-separated list (for example, 1,2,3,4).

Full access

The complete object is written with one access and all subindexes are set at the same time. The time needed for the transfer is reduced because not every subindex has to be transferred individually.

Byte array

Values can be specified as a comma-separated byte array.
