7.4.4 Supported transmission modes
The various transmission types can be selected for every process data project (PDO)
in the network management (NMT).
The following transmission types are supported for Rx-PDOs:
Rx PDO transmission mode
Transmission
type
Mode Description
0 – 240 Synchronous The received data are transmitted to the inverter as soon as the next synchronization mes-
sage is received.
254, 255 Asynchronous The received data are transmitted to the inverter without delay.
The following transmission types are supported for Tx PDOs:
Tx PDO transmission mode
Transmission
type
Mode Description
0 Acyclic synchronous Tx PDO is only transmitted if the process data have changed and a SYNC object was re-
ceived.
1 – 240 Cyclic synchronous Tx PDOs are transmitted synchronously and cyclically. The transmission type indicates the
number of the SYNC object required for triggering transmission of the Tx PDO.
254 Asynchronous Tx PDOs are only transmitted when the corresponding Rx PDO has been received.
255 Asynchronous Tx PDOs are always transmitted as soon as the PDO data has changed.
7.4.5 Default allocation plan of process data objects (PDO)
The following table shows the default mapping of the PDOs:

INFORMATION
Tx (transmit) and Rx (receive) are depicted from perspective of the slave.
Note: Modified default settings are lost after power off and on again. This means the
settings are restored to default values after power off.
