Overview
Section 1-1
Flexible Inter-network Connections
The Controller Link Network can connect to other networks (Ethernet, SYS-
MAC NET, SYSMAC LINK, and another Controller Link network) via CVM1,
CV-series, or CS-series PLCs. By installing a Communications Unit for the
Ethernet, SYSMAC NET or SYSMAC LINK on the same CS-series or CV
series-PLC as a Controller Link Unit, a message service can be created with
nodes in interconnected networks through the CVM1 or CV-series PLC. Up to
three network levels are possible.
Note CS-series PLC cannot be installed on SYSMAC NET and SYSMAC LINK net-
works.
The programming and monitoring of other PLCs on the network can be con-
ducted from Programming Devices connected to the PLC’s CPU Unit. Inter-
network connections are possible in this case also and can cover up to three
network levels.
Improved Error Handling
An error log enables quick handling of errors by recording the time the error
occurred and error details. The current Controller Link Unit and Support
Board status are also available, as are the data link and network status.
When an error occurs in the polling node that controls the Controller Link Net-
work, another node automatically becomes the polling node. This prevents an
error at a single node from influencing other nodes on the network, achieving
a highly reliable system.
In the token-ring mode in an Optical Ring System (H-PCF or GI cable), data
transmission will be unaffected even by a cable or connector break at one
location in the ring connection. Also, with the disconnect detection and notifi-
cation function, the location of a disconnection can be checked, making it pos-
sible to prevent system crashes in advance by facilitating inspection and
maintenance.
Greater Reliability with Duplex Communications Units System
By mounting the CS1W-CLK12-V1 or CS1W-CLK52-V1 to a CS1D PLC (see
note 1), Controller Link Units can be used in duplex operation. The settings for
duplex operation can be performed easily.
If an error occurs at the active Controller Link Unit, the standby Controller Link
Unit will take over operation, and communications operation will continue.
Note
1.
Controller Link Units can be used in duplex operation only in CS1D Sys-
tems with CS1D CPU Units mounted to Duplex Backplanes. (Duplex oper-
ation is possible for either duplex or simplex systems.) For details on the
CS1D, refer to the CS-series Duplex System Operation Manual (W405).
Duplex settings for Controller Link Units can be performed with CX-Pro-
grammer Ver. 3.0 or later.
2.
Active/standby switchover will take place when the following errors occur
at the active Controller Link Unit.
• EEPROM error
• Error in the communications controller’s transmitter
• Hardware error in the communications controller
• Watchdog timer error
Using token-ring mode allows transmission path duplication. This means that
communications are not affected if there is a cable or connector disconnection
at one point in the network. Also, the location of a disconnection can be iden-
tified by the disconnect detection and notification function (supported by exist-
ing models), allowing maintenance to be performed quickly and system
failures to be prevented.
