For FW versions 1.16.00.001 or earlier, the maximum total number of bytes in the RX direction is 20 bytes. This is the sum of the number of bytes in all 4 RXPDOs.touchprobe/latch filter distances). Instead of consuming Process Data Object (PDO) mappings to achieve this, which would unnecessarily consume available EtherCAT cycle time, these settings/parameters can be modified by the AC500 PLC using Service Data Object (SDO) access instead. I have a RT ETS PC running a EtherCAT master, I connected third party hardware and reading the PDO data works great at 1kHz. But now I want to read the SDO but it doesn't work.

The input and output data of the EtherCAT slave are represented as CANopen process data objects (PDO). If the EtherCAT slave supports it, this dialog allows the user to select a PDO via the PDO list and to vary the content of the individual PDO in the "PDO Content" list view.The EtherCAT process data configuration allows very flexible PDO description. PDO configuration can be either fixed, selectable or configurable. When using MDP objects, inputs (obj0x6000 – 0x6FFF) and outputs (obj0x7000 – 0x7FFF) are mapped to PDO Mapping objects (obj0x1600 – 0x16FF for RxPDO Mapping and In CoE, SDO are delivered and returned using a Data Link type called “MailBox” or “MailBox protocol”. There can be multiple messages in one MailBox. The EtherCAT message, with the MailBox, is sent separate from the Process data message or PDO. You will need to capture a trace with SDO activity in it.

After step 10, you should see the stack sources and XML being generated in the folder you select. Step 12, 13 and 14 should be applied in "protocols\ethercat_slave\ecat_appl\EcatStack\tiescappl.c" file.The CoE protocol includes process data objects (PDO) and service data objects (SDO). Nearly all existing CANopen stacks can be used without modification because the SDO protocol is implemented directly. PDO stacks are transferred by the faster, deterministic EtherCAT hardware, but are no longer subject to the 8-bit limitation of CANopen.2 Jun 2020 ...
