No, the master just writes the control byte to the slave.

Maybe the slave does not accept the Pdo configuration. Could you please
supply the following files:

- the vendor-supplied slave description XML file,
- a master-generated slave description XML file ('ethercat xml
  -p<your-slave>'),
- if possible, the generated C-code (<your-model>-etl-rtw/<your-model>.c),
- the output of 'ethercat config -v -p<your-slave>
- the output of 'ethercat pdos -p<your-slave>'
- and the output of 'ethercat slaves -v -p<your-slave>'

Then we can analyze the problem. Concerning the sync manager error in
Simulink, this is probably a bug in the ec_slave2 s-function, that we'll
have to fix.

Yes, 0x22 means that the master shall read from the sync manager memory
and the user event shall be active.
