No, but this does not make sense in most cases, because you'll have to
know exactly, which PDO entries you want to use, anyway. The master
usually is the one, that defines the bus configuration and the mapping.

Anyway, the next EtherCAT master release 1.4.0 will support you with
this task by supplying tools to create a valid configuration based on
the existing slaves and their current mapping.

Best regards,
Florian Pose
