DeviceNet / CANopen

9.7.4 Other implementation notes

Bus expansion is maximized by dividing into two sub-segments:
• Without DT: 1x max. bus length
• With DT: 2x max. bus length + optical path
With DeviceNet, make certain that participants with large quantities of data or long response times are
as high as possible in the scan list.
If the master of a DeviceNet network regularly begins a new scanning process even though not all
slave responses have been received, proceed as follows:
1. Make certain that participants with large quantities of data or long response times are as high
as possible in the scan list. If not, the order should be rearranged.
2. Increase interscan delays until all responses are received within a single scanning cycle.
