Tab: EtherCAT Slave – Expert Mode Process Data

The tab provides a more detailed view of the process data that is also displayed in the “Process Data” dialog. In addition, PDO assignment and PDO configuration can be downloaded on this tab.

Requirement: Expert settings are enabled for the slave.

Table 463: Sync Manager
List of Sync Managers with data size and PDO type.

Table 464: PDO assignment (16#1C12)
List of PDOs assigned to the selected “Sync-Manager”.
When a check box is selected, the corresponding PDOs are enabled and I/O channels are created. This is similar to the simplified PDO configuration view.

Table 465: PDO list
List of PDOs assigned to the selected “Sync-Manager”.
Entries can be added, edited, or deleted using the corresponding commands (“Add”, “Delete”, “Edit”) in the command bar or context menu.

Table 466: Edit PDO list
“Name”
“Index”
“Direction”	“TxPDO (input)”: : The PDO is transmitted from the master to the slave. “RxPDO (output)”: : The PDO is transmitted from the slave to the master.
“Flags”	“Required”: The PDO is required and cannot be disabled in the “PDO assignment”. “Windows contents”: The contents of the PDO are fixed and cannot be modified. It is then not possible to add entries in “PDO contents”. “Virtual PDO”: Reserved for future use.
“Exclude PDOs”	It is possible to define an exclusion list. When a PDO is enabled in the “PDO assignment”, others are disabled and cannot be enabled.
“Sync unit”	ID of the Sync Manager to which the PDO is to be assigned.

Table 467: PDO Contents
Displays the contents of the PDOs selected in the “PDO list”. Entries can be added, edited, or deleted using the corresponding commands (“Add”, “Delete”, “Edit”) in the command bar or context menu. The PDO order can be changed using “Move Up” and “Move Down”.

Table 468: Download
“PDO assignment”	: Specific CoE commands for initializing the `‎0x1cxx‎` objects are generated and written to the slave.
“PDO configuration”	: The CoE commands for `‎0x16xx‎` or `‎0x1axx‎` are generated, and then the PDO mapping is downloaded to the slave. Normally, the default values originate from the ESI file and the device has to support this functionality. For example, if a device has a fixed configuration, then these commands are regarded as flawed.
“Load PDO info from the device”	The current PDO configuration is read from the slave and entered into the configuration. The lists in the upper and lower right are then deleted and filled with the read data. This is especially useful when the ESI file is incomplete and the configuration is available only on the slave.
