9.2 Configuring CANopen Slave
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
Export the EDS file of the PN/CAN LINK. Click the "Export EDS file" button
corresponding file selection dialog.
Figure 9-13
Allowing PN/CAN LINK to transition to "Operational" via the S7 user program
To enable the PN/CAN LINK to transition to "Operational" state and thus the transmission of
data between the S7 controller and the PN/CAN LINK, you must set the control bit to "1"
using the S7 user program. This control bit is cyclically transmitted from the S7 controller to
the PN/CAN LINK as part of the IO data. However, the actual state transition must be
triggered by the current NMT master.
