9.2 Configuring CANopen Slave

Setting PN/CAN LINK to "Operational" with the S7 user program
To enable 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.
Note
In "CANopen Manager" mode, bit 2 must also be set to "1" in the control information
transmitted from the S7-CPU to the PN/CAN LINK. You can find additional information on
the effect of the control bit under Control and status information (Page 28).

Overview

Configuring using HSP in the TIA Portal (PN/CAN LINK is NMT slave)
The PN/CAN LINK is configured in the TIA Portal. The configuration for "CANopen Slave"
operating mode mainly consists of the following steps:
1. Import PN/CAN LINK HSP into the TIA Portal.
2. Drag PN/CAN LINK from the HW catalog to the project.
3. Set the PROFINET-specific parameters.
4. Set the "CANopen Slave" operating mode.
5. Set bus-specific parameters for the "CANopen Slave" module: Node ID and transmission
rate
6. Create OD entries for the process data to be exchanged between the S7 controller and
the CANopen network.
7. Check and compile the configuration.
8. Export the EDS file.
