Installing Connectors

Connect all the nodes in a ring using GI Optical Fiber Cables.
Refer to the following diagram when making the connections.
Connect the upper node SL2 receive connector to next lower node SL1 send
connector and connect the upper node SL2 send connector to next lower
node SL1 receive connector.
Receive Send
The connector with the triangle facing up is the receive con-
nector, and with the triangle facing down is the send con-
nector. The color of the triangle indicates the upper node
Board and next lower node Board; Be sure to connect
triangles of the same color.
There is an ID mark on one end of each pair of Optical Fiber Cables. Use this
mark to identify the code.
Incorrect connections may result in a broken wire being incorrectly detected,
and may cause unexpected operation.
The nodes can be connected in any order, but connect the nodes in the order
of node addresses (i.e., node 1, node 2... node 62) as much as possible to
reduce the effect on the communications time if a wire breaks.
Refer to 2-1-1 Devices Required for Connection for details on available Opti-
cal Fiber Cables. Refer to page 38 Installing Connectors for details on con-
necting the Optical Fiber Cables to the Controller Link Board.
1. Always use the specified Optical Fiber Cables.
2. The code for the Optical Fiber Cables can be identified from cable marks
and color, but OMRON recommends adding tags to prevent incorrect con-
nection during installation.
3. The maximum distance between the nodes depends on the type of GI ca-
ble (core diameter), as described below.
62.5/125 μm: 2 km maximum distance between nodes
50/125 μm: 1 km maximum distance between nodes
A special connector is used to connect the Optical Fiber Cable to the Control-
ler Link Support Board.
Connect the nodes in order beginning with the highest node in the network
and continuing on to lower nodes. When connecting a ring, also connect the
end node in the ring to the start node.
• Always turn OFF the computer and backup power supply before connect-
ing Optical Fiber Cables or the backup power supply connector.
