Network Topology

Concerning the usage of CP-Link 3 please note the following:

▪

It is recommended to use a separate network for CP-Link 3.

▪

The PCs used in the network have to be connected together using tree structure, i.e. clients are connected to the host PC either directly or via one or several switches. Ring structures, bus structures or serial structures (daisy chaining) are not possible.

▪

The maximum length of the network cable between two PCs or switches is 100 m.

▪

If a host PC uses the USB Bus Couplers built into the clients via RT-Ethernet, it might be necessary to use a separate network for RT Ethernet (see also Using the CPx8xx USB Bus Coupler).
