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 Optical
Fiber Cables. Refer to 2-2-3 Installing Connectors for details on connecting the
Optical Fiber Cables to the Controller Link Board.
Note 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 cable
(core diameter), as described below.
62.5/125
µ
m: 2 km maximum distance between nodes
50/125
µ
m: 1 km maximum distance between nodes
2-3-3 Installing Connectors
A special connector is used to connect the Optical Fiber Cable to the Controller
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 connecting
Optical Fiber Cables or the backup power supply connector.
•
Special tools are required to attach Optical Fiber Cables to the connectors.
The cable may disconnect from the connector if the proper tools and methods
are not used during cable assembly.
Connection Procedure
1, 2, 3... 1. Secure the Optical Fiber Cable tension member.
