Configuration Error in a Sync Manager

Configuration errors in one of the Sync Managers can occur during status change
from INIT to PREOP or from PREOP to SAFEOP. These lead to a denial of the
requested status change by the corresponding AL status code.
Additional information about AL status codes!
A list of the AL status codes and their meanings can be found in the appendix,
"AL Status Codes" chapter.
The settings of Sync Managers 0 and 1 (mailbox) are checked during status
change from INIT to PREOP.
The master extracts the settings either from the SII (slave's EEPROM) or from
the optional XML file with the device description of the EtherCAT
