PGN input modules
Set the PGN parameters according to your requirements. The meaning of the
PGN parameters can be found in the section PGN parameters (Page 19).
Figure 9-4 PGN input module with a data length of 16 bytes
The received data is available at the input address of the module.
PGN output modules
Set the PGN parameters according to your requirements.
For PGN modules with a data length of 8 bytes, the transmission occurs as a standard
message within a CAN data frame. PGN modules from 16 bytes data length are fragmented
and transmitted via a transport protocol. If the data length exceeds 16 bytes, also select a
suitable transport protocol for the transmission.
Figure 9-5 PGN output module with a data length of 16 bytes
The PGN data to be sent must be assigned to the output address of the module. Only the
pure user data of the PGN message is sent via the CAN network.
Note
A value for the send cycle is only valid if you ha
ve set the "cyclic" send event.
The meaning of the individual PGN parameters can be found in the section PGN parameters
(Page 19).
