EtherCAT

Master

EtherCAT Terminals can be configured and parameterized via the EtherCAT / Master Device Manager page.

EtherCAT Master

The current state of the EtherCAT Master on the EK coupler is displayed here. Normally the EtherCAT master should be in OP.

Network Statistics

The EtherCAT statistics are output here.

EtherCAT Slaves

Display of the EtherCAT slaves and their states. The Restore State indicates whether a Restore File has been created for the terminals.

Configuration & Restore File

The Restore File is required in order to be able to parameterize EtherCAT Terminals again. If EtherCAT Terminals are replaced and have been parameterized, this parameterization is usually lost when the EtherCAT Terminals are replaced. The Restore File reloads the parameters to the corresponding new terminal when the coupler is started. The Restore File must be created if you want or need to change the default mapping of the terminals.

• Restore State
• EMPTY
  means there is no restore file for the terminal
• VALID
  a valid Restore File has been created
• MAPPING
  The terminal mapping has been changed, but is not yet stored in the Restore File.

EtherCAT Slaves Mappings

In some EtherCAT Terminals the process image can be changed; it must be stored in the EtherCAT master. The terminals that can be changed are displayed under “EtherCAT Slaves Mappings”, the corresponding mapping must be set and stored in the Restore File. A restart of the coupler is required so that the coupler can activate the mapping (note: this changes the process image).

Parameterization of the EtherCAT Terminals

To parameterize an EtherCAT Terminal, select the corresponding terminal in the Device Manager. The terminal objects are then displayed and can be edited if necessary. The settings are then stored in the terminal. Note that any modifications are lost if the terminal is replaced. In this case, use the restore file (see above), as your changes are also stored in the Restore File.

The screenshot "Configuration via Device Manager - Parameterizing the EtherCAT objects" shows the parameterization of the EtherCAT Terminal. The thermocouple type of an EL3318 is changed to another type by the selecting object 8000:19.
