Setting Up EtherNet/IP Network (Scenarios)
When setting up a network, various settings are necessary in order to connect devices to each other and exchange data. The steps necessary for configuration depend on the application, and, thus on the devices used and their roles as master or slave.
The following applications will be considered:
- Connect Controller (master) to WAGO Device (slave)
- Connecting Controller (Master) to Controller (Slave)
- Connecting Controller (Master) to Third-Party Device (Slave)
- Connect Controller (master) to Third-Party Device (slave) without EDS file
The procedure described below for the individual applications represent the general process for performing the configuration.
The order may vary. Depending on the communicating device selected, individual steps may be largely or entirely omitted.
- Select Devices
For devices to be used in e!COCKPIT, they must be known within e!COCKPIT, i.e. they must be available in the product catalog. The installation of e!COCKPIT automatically makes WAGO devices available in the product catalog. Third-party devices are added to the product catalog by importing a device description file. If no device description file is available, so-called “generic devices” are available in the product catalog for configuration. - Place Devices in the Communication View
Devices are scanned or dragged from the product catalog into the communication view. - Configure the I/O Modules Used in the Device Detail View
If the device has I/O modules, they can be added automatically through a scan and displayed in the Device Detail view. Alternatively, I/O modules can also be placed in the Device Detail view directly from the product catalog even without an online connection.
Note: Third-party devices cannot be scanned. - Connect Devices
Devices are connected on the communication layer through connectors. If unique assignment of the “master” and “slave” roles is possible, this is performed automatically on the basis of the device. The arrow on the connection line points from the master to the slave. - Make the Device Settings on the “Settings” Panel
The device settings on the “Settings” panel are displayed in a context-sensitive way for the specific selected device and its communication interfaces and can be modified as needed. - Configure Slave
Connections and slave data points can be created and configured in the data point configurator. These are published and can be used by the master (see also Slave Settings in the Data Point Configurator). - Configure Connection between Master and Slave
In the fieldbus configurator, you can determine the communication relation for the master and slave. This determines which connections should be established between master and slave. Furthermore, slave data points are mapped to program variables (see also Master and Connection Settings in the Fieldbus Configurator). - Access Data Points
Slave data points that have been created can be accessed from the master’s application.
