<strong>CAN</strong>open-Software<br />
Apart from basic descriptions of the <strong>CAN</strong>open, this chapter contains the most significant information<br />
about the implemented functions.<br />
A complete <strong>CAN</strong>open description is too extensive for the purpose of this manual.<br />
Further information can therefore be taken from the CAL/<strong>CAN</strong>open documentation ‘CiA Draft<br />
Standard 301, V 4.02’ and ‘CiA Draft Standard Proposal 401, V 2.1’.<br />

PDOs (Process Data Objects)<br />
PDOs are used to transmit process data.<br />
In the ‘Transmit’-PDO (TxPDO) the <strong>CAN</strong>-<strong>CBX</strong>-<strong>AI420</strong> module transmits data to the <strong>CAN</strong>open<br />
network.<br />
SDOs (Service Data Objects)<br />
SDOs are used to transmit module internal configuration- and parameter data. In opposition to<br />
the PDOs SDO-messages are confirmed. A write or read request on a data object is always<br />
answered by a response telegram with an error index.<br />
