Optical Fiber Cable Connections for H-PCF Cable
Optical Bus and Optical
Ring Systems (Token-bus
Mode)
All of the nodes in the network are connected in a line (daisy-chain configura-
tion) with H-PCF Optical Fiber Cable.
The nodes can be connected in any order, but be sure to begin with the upper
connector (SL1) of the highest node in the network and connect to the lower
connector (SL2) in the next lower node, as shown in the following diagram.
Although there is no fixed order in which the nodes must be connected, in
order to minimize the effect on communications time in the event of a discon-
nection, it is recommended that they be connected in order of node address
(node 1
→
node 2...
→
node 62 whenever possible).
Also be sure to cover the unused connectors on the highest and lowest nodes
in the network with Optical Connector Covers.
See 1-2-6 Devices Required for Connection for details on available H-PCF
Optical Fiber Cables.
Note
1.
Always use the specified Optical Fiber Cables.
2.
The maximum distance between nodes depends on how the cable is con-
nected. For details, refer to the applicable Optical Fiber Cable (H-PCF)
manual.
3.
In token-bus mode (daisy-chain connection), the maximum number of
nodes in an Optical Bus System (i.e., Controller Link Unit model numbers
ending in CLK11) with nodes is 32 (node addresses 1 to 32).
4.
Duplex operation of Communications Units is not possible in token-bus
mode.
5.
Online replacement is possible in CS1D Systems but if token-bus mode is
used there is a possibility of the network splitting.
Optical Ring System
(Token-ring Mode) without
Duplex Operation
All of the nodes in the network are connected in a ring with H-PCF Optical
Fiber Cable.
The nodes can be connected in any order, but be sure to begin with the upper
connector (SL1) of the highest node in the network and connect to the lower
connector (SL2) in the next lower node, as shown in the following diagram.
Although there is no fixed order in which the nodes must be connected, in
order to minimize the effect on communications time in the event of a discon-
nection, it is recommended that they be connected in order of node address
(node 1
→
node 2...
→
node 62 whenever possible).
