I understand about SDO's, have sent them to a module (Maxon Epos motor control). I have used them to read/write register entries from the Object dictionairy successfulley. Have used this site as reference as well;
However, I do not completely understand about PDO's. What I'd like to know, is how I can make the CAN Node automaticly send a PDO containing a certain value obtained from one of the specified address in for example the 1st Mapped Object in TxPDO 1 ?
When I look in the Node's Object dictionairy, I can see that the Pdo transmission type is set to 0xFF, which is 255, and according to this site:
Do I need to send something first in order to let the Node send automaticly some of its input values when they change?
