the sequence in which the system manager displays the PDOs. For instance the PDO communication parame-
ter of the third listed TxPDO are always written to index 0x1802 - independent of the name of the PDO in the
system manager. So if only PDO1 and PDO3 are to be used, PDO2 has to be entered as well - in this case
without variables assigned. PDOs without variables are not sent and are not expected by the card.
Context menu:
The menu alongside is obtained by right clicking on the general CANopen node. Here you can insert further Tx
PDOs and/or Rx PDOs.
”SDOs” tab
SDO inputs sent to the node at StartUp are displayed/managed on this page. Inputs with an object index in
straight brackets are automatically created on the basis of the updated terminal configuration. Other inputs can
be managed using ”Add”, ”Insert”, ”Delete” and ”Edit”.
”ADS” tab
In order to be able to read and write SDO objects during the running time (e.g. from the PLC), the node (Bus
Coupler) can be allocated an ADS port (CIFx0-CAN). The FC510x provides an ADS port at all times for every
node since the diagnostic information is transported via ADS. These ports can be used to read and write SDO
objects using ADS read requests and/or write requests.
The ADS IndexGroup contains the CANopen object index and the ADS IndexOffset contains the CANopen
SubIndex.
