4.3 Network topology

Control Techniques recommend implementing daisy chaining on EtherCAT networks

(see Figure 4-1). Other Ethernet network topologies can be used but care must be taken

to ensure that the system still operates within the constraints specified by the designer.

4.4 Minimum node-to-node cable length

There is no minimum length of cable recommended in the Ethernet standards. To avoid

possible problems it is recommended that you allow sufficient cable length to ensure

good bend radii on cables and avoid unnecessary strain on connectors.
