Documentation Help Center. This example requires a dedicated network card that is installed and available on the target computer. Use the dedicated card for the EtherCAT communication. The dedicated card is in addition to the card used for the Ethernet link between the development and target computers.
This model drives a pulse wave signal and transmits the signal and its inverse as Boolean values to the EL terminal, and receives the input signal transmitted by the EL terminal. Copy the example configuration file from the example folder to the current folder. Then, open the model. To get these values, in the Command Window, type tg. This file describes the network to the master. An overview of the process for creating the configuration file in the EtherCAT configurator is:.
Connect the network consisting of terminals EK, EL, and EL in this example to the computer where the EtherCAT configurator is installed and scan the network to discover the connected devices. Define at least one cyclic task, select a task execution rate, and associate the selected variables to the task. Export the configuration file into an XML file. Each EtherCAT configuration file is specific to the exact network setup from which it was created for example, the network discovered in step 1 of the configuration file creation process.
The configuration file defines a set of transmit and receive variables. For this example, four receive variables are defined for the four input channels of Terminal EL Only the first two channels of Terminal EL are used in this example. These two variables are 'Term 3 EL Channel 1. Input' and 'Term 3 EL Channel 2. In the same way, four transmit variables are defined for the four output channels of terminal EL, but only the first two channels are tested in this example.
These two variables are 'Term 2 EL Output' and 'Term 2 EL Take a snapshot of the target computer video display. Plotted are the signals transmitted to terminal EL and received from terminal As expected, the transmitted and received signals displayed on the two scopes are identical. Scope 1 displays the outputs of the Ethercat Init block. See the documentation of this block for the meaning of the displayed values. Scope 3 displays the signals received at the two inputs ports of Terminal EL A modified version of this example exists on your system.
