Defining a receive data OD
The steps for defining and assigning the receive data ODs are analogous to those for transmit
data ODs:
1.
Create receive data object directory
2.
Define receive OD index and subindex
Adapting I/O addresses
If necessary, you must adapt the I/O addresses assigned automatically by the TIA Portal. This
is possible, for example, in the "Device overview" window. Here you can also find the I/O
addresses used by the slots. In particular, the addresses assigned to slot 1, that is the
"CANopen Slave" module, are important because the control and status information is
exchanged with the S7 program via these addresses. It is important for startup of the PN/CAN
LINK that the control information transmitted here from the S7 program is set correctly.
Checking data consistency
You can check the consistency of the assignments as well as the data types used with a
compilation.
Exporting the EDS file
Set the number of desired process data objects.
Export the EDS file of the PN/CAN LINK. Click the "Export EDS file" button
①
to open the
corresponding file selection dialog.
Note
Define only as many process data objects (PDOs) as you actually need for transmissions. A
large number of unnecessary PDOs can significantly slow down the processes in the TIA
project when importing an EDS file into the CANopen Manager.
