Tab: EtherCAT Slave – Start Parameters

On the tab, the SDOs (service data objects) for 'CAN over EtherCAT' (CoE) or the IDNs (identification numbers) for 'Servodrive over EtherCAT' (SoE) are defined for the current slave. These parameters are determined for the device when the system is started.

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

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

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

List of SDOs or IDNs

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

Line

Line number

Index:Subindex

For CoE only

IDN

For SoE only

Identification number

Name

Bit length

Bit length of the SDO or IDN

Abort on Error

standard icon: In case of error, the transfer is aborted with an error status.

Jump to Line on Error

standard icon: In case of error, the transfer is resumed with the SDO or IDN at the specified Line.

Next Line

standard icon: The transfer is resumed with the SDO or IDN at the next line.

Comment

Input field for comments

Move Up

Moves the selected line upwards by one line

Move Down

Moves the selected line downwards by one line

Add

Opens the Select Item from Object Directory dialog adding SDOs or IDNs.

Delete

Removes the selected entry.

Modify

Opens the Select Item from Object Directory dialog for changing the parameters of the selected SDO or IDN

Dialog: Select Item from Object Directory

The dialog lists all available object directory entries as defined in the XML file. The parameters of the objects can be modified in this dialog. New objects can also be created. This is useful when none or only an incomplete object directory exists.

Table 30. CAN over EtherCAT

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

Column Index:Subindex

Identifies the entry in the object directory

Column Name

Column Flags

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

Column Base Value

Editable (double-click to open)

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

Each value may be max. 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

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



Table 31. Servodrive over EtherCAT

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

Column IDN

Identification number

Column Base Value

Base value of the IDN.

Double-click to modify.

Input fields

IDN

Identification number: Composed from the subsequent parameters

  • S: Standard data

  • P: Product-specific data

  • PSet: Parameter set

  • Offset

Bit length

List box for selecting the bit length

Value

List box for selecting the value

Channel

If the object has multiple subobjects, then this list box is displayed automatically.

As list

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

standard icon: The length is calculated automatically.
