Tab: EtherCAT Slave – Process Data

The tab displays the process data for the inputs and outputs of the slave. The data is predefined from the device description file.

Table 24. Select the Outputs

The table shows the outputs of the slave defined by Start address, Type, and Index.

If outputs of the device are enabled here (for writing), then these outputs can be assigned to project variables in the EtherCAT I/O Mapping dialog.

Table 25. Select the Inputs

The table shows the inputs of the slave defined by Name, Type, and Index.

If inputs of the device are enabled here (for reading), then these inputs can be assigned to project variables in the EtherCAT I/O Mapping dialog.

Table 26. List box with predefined PDO assignments

If vendor-specific tags (non-standardized tags) are defined in the ESI file of the EtherCAT Slave, then alternative Sync Manager assignments are available. You can toggle between these PDO assignments. To do this, select the desired predefined PDO assignment from the list box.
