Constructing Networks with Repeater Units Section 3-4

Units/Support Boards or Repeater Units) at both ends of each network segment created by installing Repeaters must also be turned ON.

To construct a 62-node configuration in a wired network, all network nodes must consist of one of the following models:

CS1W-CLK21-V1, CJ1W-CLK21-V1, 3G8F7-CLK21-V1

The following Wired Network 62 Node Enable Bit in the DM Parameter Area software switch on each node must be turned ON to enable using 62 nodes maximum:

4.Repeater Units can be connected in a network in advance if new nodes are to be added to the network after the system has been constructed. When it becomes necessary to add a node, cabling can be accomplished easily by simply wiring a T-Branch to the Repeater Unit. This method also allows nodes to be added without stopping communications over the existing net- work.

3-4-1 Segments

Repeater Units divide a wired Controller Link network into segments. Seg- ments are comprised of nodes connected in a multi-drop configuration using wire cables. The specifications of the network within a segment are identical to the wired Controller Link network itself. The specifications within a single segment are shown in the following table.
