In order to reduce process data size, TwinCAT overlaps the
RxPDO and TxPDO for each module, then uses the LRW command to
effect the transfer. So, I believe what you're seeing is normal.<br>

Subject: [etherlab-users] Domain offset overlap

Hi all,
I have written some code to parse the generated XML file from "ethercat xml" and use that to configure the ethercat stack. The problem I am having is the output from ecrt_slave_config_ret_pdo_entry produces overlapped offsets. I also tried using ecrt_slave_config_reg_pdo_entry_pos with the same results. This is a very simple test rig that has one each of DO, DI, AO, and AI slices - all beckhoff. I have attached a file which includes the generated XML file, the code in question, and the log output. Does anyone know what I am doing wrong?
Best regards,
Steven Hartmann</pre>
