Process SYNC telegram

If synchronous PDO's have been created in an frequency inverter, their processing is
synchronized with the SYNC telegram. The SYNC telegram is generated by the system
bus master and is a telegram without data.
The identifier is 128 according to the Predefined Connection Set.
If a PC or PLC is used as a master, the identifier of the SYNC telegrams can be
adapted by parameterization on the frequency inverter. The identifier of the SYNC
telegram must be set identically in all subscribers on the system bus.
Attention: The identifier range 129 ... 191 may not be used as the emergency tele-
grams can be found there.
