“Connection” Tab

On this tab, you can display, create and manage EtherNet/IP-specific connections. The connections defined here are available for selection in the fieldbus configurator for the master.

There are two methods for integrating slaves into e!COCKPIT. The settings you make here depend on the method used:

  1. Integration via an EDS File
    By default, devices are integrated into the product catalog via an EDS file and instantiated in the network view. The information from the EDS file is automatically displayed in the data point configurator. On the “Connection” tab, all connections specified in the EDS file are automatically created with their predefined parameters and can be configured and parameterized further.
    A connection from the EDS file is not created in the following cases:
    • The connection contains unsupported data points or configuration parameters
    • The connection does not support “transport class 1”
    • In the “connection parameters,” “safety” is set as the “real time transfer format”
    • Proxy communication is specified for the connection
    • A “SYMBOL_ANSI” symbol is specified as the path for the connection
  2. Integration via a Generic Adapter
    The generic adapter “Generic_EtherNet/IP_Adapter” is available in the product catalog and can be used as a substitute for a device for which no EDS file, and thus no specified configuration, is available. Therefore, for generic adapters, connections with data points and configuration data, as well as user parameters, can be created manually. The configuration must be performed according to the product manual of the device. All settings options of the data point configurator are available for this purpose. However, manual configuration should be the exception, because every manufacturer usually offers an EDS file for its devices.

Parameter

Description

Connection Name

Name of the connection

Application Type

Indicates the application type per the EtherNet/IP standard:
“Exclusive Owner,” “Listen Only,” “Read Only” or “Redundant Owner.”

Input Size (T → O)*

Byte size of the data that the slave sends to the master via the input assembly instance

Output Size (O → T)*

Byte size of the data that the slave receives from the master via the output assembly instance

Configuration Size (Target)

Byte size of the target configuration

Path

The path specifies the addressed assembly instances.

Comments

Input field for comments

* Note: Note that the input/output data sizes are limited:
• max. 505 bytes with the real-time transfer format setting “32 bit header“
• max. 509 bytes for all other real-time transfer format settings
(for the real-time transfer format, see Editing a Connection in the fieldbus configurator)

The following functions are available in the context menu (right-click on a row) and via buttons for creating a new connection or editing a connection:
