Optical Ring System (GI Cable) Wiring

GI Optical Fiber Cable Wiring
Optical Ring System in
Token Bus Mode
All of the nodes in the Optical Controller Link Network are connected in a line
(daisy-chain configuration) with H-PCF Optical Fiber Cable.
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.
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.
Also be sure to cover the unused connectors on the highest and lowest nodes
in the network with the provided Optical Connector Covers.
Refer to
2-1-1 Devices Required for Connection
for details on available Opti-
cal Fiber Cables. Refer to
for details on connect-
ing 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 ca-
ble (core diameter), as follows:
62.5/125
μ
m: 2 km maximum distance between nodes
50/125
μ
m:
1 km maximum distance between nodes
