CANopen Device Node IDs
On the Parameters tab, you can set the maximum node ID of the last module on the
island bus. Standard CANopen devices follow the last segment of STB I/O modules.
CANopen modules are addressed by counting backwards from the value you enter
here. The ideal node ID sequence is sequential.
For example, if you have an island with five STB I/O modules and three CANopen
devices, a maximum node ID of at least 8 (5 + 3) is required. This will result in node
IDs of 1 through 5 for STB I/O modules and 6 through 8 for standard CANopen
devices. Using the default ID of 32 (the maximum number of modules the island can
support) will result in node IDs of 1 through 5 for STB I/O modules and 30 through
32 for standard CANopen devices. Those unnecessarily high addresses are not
desirable if any of your standard CANopen devices have a limited address range.
Assigning the Max. Node ID (CANopen Devices)
To enter the highest node ID used by a CANopen device on the island bus:
Step Action Comment
1 In the module editor window, select the
Parameters tab.
Configurable parameters are on this tab.
2 In the box next to Max. node ID on the
CANopen extension, enter a node ID.
This node ID represents the last
CANopen module on the island bus.
