Overview Section 1-1
Transmission Path
Duplication In the token-ring mode in an Optical Ring System (H-PCF cable or GI cable),
data transmission will be unaffected even by a cable or connector break at
one location in the ring connection. With the fiber-optic cable wired in a ring
shape, a break at one point will simply cause the transmission to be routed in
the other path.
Disconnect Detection and
Notification Even with transmission path duplication, the network will be broken if discon-
nections occur in two or more places. In the token-ring mode in an Optical
Ring System (H-PCF cable or GI cable), the location of a disconnection can
be detected and can be identified by means of the status display for all nodes.
This function can be used to prevent system crashes in advance, by perform-
ing maintenance when a disconnection occurs at one place.
Node Connection
Configuration Data
Reading In the token-ring mode in an Optical Ring System (H-PCF cable or GI cable),
connection data can be read for all of the nodes configured in the network.
The information that can be read includes the order in which the nodes are
connected and which of two optical connectors is connected to which node.
Special support software (Controller Link Support Software, Ver. 2.00 or later)
is required in order to read the node connection configuration data.
Duplex Units By mounting the CS1W-CLK12-V1 or CS1W-CLK52-V1 to a CS1D PLC, Con-
troller Link Units can be used in duplex operation. If an error occurs at the
active Controller Link Unit, the standby Controller Link Unit will take over oper-
ation, and communications operation will continue. Also, Controller Link Units
with errors can be replaced without turning OFF the power (i.e., online
replacement).
1-1-2 Features
The Controller Link Network has the following features to meet the various
requirements of FA sites.
Data Links
Flexible and efficient data links can be created for large capacities of data as
listed below.
Data links can be automatically set, or they can be set by the user to freely
change the sizes of the data areas used. A data link can also be created so
that one node receives only part of the data sent from another node. This
function enables users to receive only the required data, thereby increasing
data link efficiency.
