What happens?
The following error message appears:
PDO upload failed! Some data could not be read.
When does this behaviour occur?
The error message appears when clicking the <Load PDO Info from the Device> button on the 'Expert Process Data' tab of an EtherCAT slave.
The button is active if the 'Enable Expert Settings' checkbox is activated on the 'General' tab of the EtherCAT slave and an online connection is established after that (menu command 'Online>Login').
Which products are affected?

Short-term measures:
Do not click the <Load PDO Info from the Device> button. Manually enter the PDO Configuration and the PDO Assignment on the 'Expert Process Data' tab.
Evaluation/recommendations:
Clicking the <Load PDO Info from the Device> button leads to an error message. The button is only active in the Expert Settings mode. An applicative solution is described under 'Short-term measures'.
