Flexible Internetwork Connections
The Controller Link Network can be connected to another network (Ethernet,
SYSMAC NET Link, SYSMAC LINK, or another Controller Link network)
through a CS-series or CV-series PC. By installing Ethernet, SYSMAC NET
Link, or SYSMAC LINK, or Controller Link Communications Units on the same
CS1-series PC or CV-series PC, a message service can be created with
nodes in the interconnected networks through that PC. Up to three network
levels are possible.
Improved Error Handling (RAS Functions)
Error Log and Data Link
Status Display
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.
Polling Node Backup
Function
When an error occurs in the polling node that controls the Controller Link Net-
work, another node automatically becomes the polling node with the help of
the Polling node backup function. This prevents an error at a single node from
influencing other nodes on the network, achieving a highly reliable system.
Node Bypass Function
In an Optical or Optical Ring Controller Link Network, data communications
can be continued by bypassing the node, even when a node in the communi-
cations line malfunctions or the PC or computer power supply is turned OFF.
This prevents the whole network system from being affected by a node mal-
function or power interruption.
To use the bypass node function, backup power must be supplied to the Con-
troller Link Unit/Support Board.
