- Transmission types 1 - 240 are synchronous transmissions with regard to the SYNC messages. A value
between 1 and 240 means that the PDO is synchronously and cyclically transferred. The transmission type
indicates the numbers of SYNC which are necessary to trigger PDO transmissions.
- Transmission type 253 means that the PDO is only transmitted on remote transmission request.
- Transmission type 255 is event trigger: The PDO will be transmitted when the first object (must be 16-bit)
mapped in PDO has changed.
PDO transmission modes:
- Synchronous: the message is transmitted in synchronisation with the SYNC message. A synchronous
message must be transmitted within a pre-defined time-window immediately after the SYNC message.
- Asynchronous: the message is sent independently of the SYNC message.
Triggering modes:
- Event _Driven:
Message transmission by reception of SYNC.
Message transmission by specific event.
- Remotely requested: the transmission of an asynchronous PDO is initiated at reception of a remote request
by any other device.
