'EEPROM' tab (EtherCAT Slave Online Functions)

This topic contains the following sections:

The following information refers to a specific, typical device type. Your screen may differ.

This help topic describes the 'EEPROM' editor of the EtherCAT 'Online Functions'. In the 'Online Functions' editor, select the EtherCAT slave station to be evaluated in the tree on the left and click the 'EEPROM' tab on top of the editor on the right.

This editor tab is only available for EtherCAT slaves but not for the master.

The non-volatile EEPROM memory stores the EtherCAT Slave Information (ESI). The 'EEPROM' tab displays the parameter values currently stored in the EEPROM and it provides the possibility to modify the values.

Further Info
For detailed descriptions of the parameter values, please refer to the respective Technical Manual of the slave device.

Column Description

Index Word address in the EEPROM.
The EEPROM is divided into several areas. For example, the address range 0x0000 to 0x0007 holds the ESC configuration which is automatically read by the ESC after power-on or reset.

Name Descriptive and comprehensive parameter name.

Value Value of the parameter. The value type and range depends on the data type (see next row).
If a value is editable (indicated by the flag RW), you can modify it as described below this table.

Type Data type of the parameter.

Flag Specification whether the parameter value can only be read (Flag = RO) or also written (edited, Flag = RW).

Modifying an EEPROM value directly on the device

If a value is editable (which is indicated by Flag = RW), you can modify it as follows:

Select the object to be edited.
Enter the desired value (in decimal or hexadecimal format) into the field below the grid and select the input format with the buttons provided.
Click 'Apply'.

The new value is entered into the grid row. The network configuration is updated, i.e., the value is transmitted to the master and processed accordingly.
